Breakout Sessions That You Dont Want To Miss This Year At Citrix Synergy!

For the past couple of years, I have tried to filter through all the breakout sessions and compile my top picks. The purpose is to help my customers build their agendas, especially if this is the first time they are attending and are not familiar with the speakers. This year I have broken it down by the top 10 overall, my top 15 technical sessions, top 10 sessions for management level attendees and other picks that just missed the top 10.

General Tips For First Time Attendees

  • Do not miss the keynotes!
  • Networking with peers from the industry is one of the best aspects of attending Synergy. Make sure you take the time to reach out to others while attending sessions. Also spend as much time as possible at the expo and meet the various vendors.
  • Do not decide on attending a session just based on the title. Always check the speakers and agenda as well.
  • Provide your feedback on the sessions you attend. This will help Citrix improve future breakout sessions.
  • Do not hesitate to ask questions to the speakers either during the session or after the session. The breakout sessions are a golden opportunity to get some face time with some of the brightest minds and you should take full advantage!
  • If you are new to the products or have not played with the latest and greatest versions, make sure you stop by the Solutions Sandbox and get your hands dirty.
  • Follow Synergy on twitter. You will receive great insights on the sessions, keynotes etc. An unfiltered perspective I might add.

Driving Digital Transformation – Kirill Tatarinov, Citrix CEO

“Citrix is an enabler of digital transformation, helping customers in all industries to unlock their business potential. It has been terrific to hear resounding support for this mission in my many conversations with our customers and people around the world.”

Shelton Public Schools Saves Two Million Dollars Using Citrix Technology

“One of the most influential trends in education today is differentiated learning, whereby educators provide students with different pathways to learning in the same classroom. Shelton Public Schools, a K-12 school district in Western Connecticut, has addressed this trend by using Citrix technology to support the Google Chromebox computers that mount on the back of a monitor and retail for less than $200 – a fraction of the nearly $500 per device Shelton Public Schools would have had to spend on desktop computers for its classroom learning centers. ”

Citrix Radically Simplifies the Secure Delivery of Browser-based Apps

Citrix Secure Browser product family provides a quick, simple way for any IT organization – even those that have never used a Citrix product – to securely deliver web and SaaS applications to any modern browser. In minutes, an administrator can set up any web application to be securely delivered to any device, even internally hosted web apps, without intrusively installing anything on an employee’s device.”

Hospital CTO finds virtualization and security in Citrix

“As associate vice president and chief technology officer of Children’s Hospital Los Angeles, Sean Updegrove works to make sure his physicians get their patients’ health data safely, quickly and conveniently whether they’re on hospital rounds, at home or in the clinic. For this task, he chose Citrix technology for virtualization and security of the physician portals and workflows that transport data from Children’s Cerner Corp. EHR to clinicians as they move around the hospital.”

Biggest EMM Trends of 2015

” Serving as the “invisible middleman,” enterprise mobility management (EMM) gives IT and employees the tools and confidence they need to just say yes to workforce mobility. With empowering employees to work and collaborate the way they prefer as a baseline (hearkening back to today’s trend for organizations to adopt BYOD policies to let people use their own PCs and mobile devices for work), Citrix recently polled customers that deployed EMM in the cloud using XenMobile last year.”

iOS 9.3 – What’s In It For the Enterprise?

XenMobile provided same-day platform support for the release of iOS 9.3. With every new iOS release I’m always curious to see what’s in it for the enterprise and 9.3 doesn’t disappoint.

Citrix Unleashes Industry-First Integrated Platform for SD-WAN

Software Defined WAN (SD-WAN) offers the reliability, visibility, control and flexibility businesses need today to address the demands placed by new bandwidth intensive applications on their wide area networks—and in 2016 there is strong momentum toward mainstream adoption. Citrix unveiled a complete solution for enterprises on this path: CloudBridge Enterprise Edition, a single platform with fully integrated WAN virtualization, WAN Optimization, enterprise-grade security, and end-to-end visibility.”

The Fastest PoC in the Cloud – XenApp in the Azure Marketplace

“I am pleased to announce that you can now try XenApp 7.8 in the Microsoft Azure Marketplace. This offering is the latest addition to our already existing portfolio in the Azure Marketplace, which includes NetScaler VPX (BYOL) and ShareFile StorageZones Controller.”

Citrix Appdisks How To Guide – Administration Basics and Gotchas 

AppDisk, an application layering solution was part of XenApp/XenDesktop 7.8 released in late February this year. This post is not meant to cover the basics of application layering or image management as a whole. My goal in this post is to cover the administrative aspects of application layering using Citrix AppDisks.

Remote PC Access for XenDesktop: Not Flashy, Just Fantastic

“With over 1,500+ customers and 500,000 systems actively enrolled and using Remote PC Access, it is gaining visibility everywhere as a valuable standard in deploying XenDesktop. And who wouldn’t adopt it? Combining the power of HDX, energy cost savings with Wake on LAN (WOL) and security provided by NetScaler, its simple deployment model appeals to every vertical and every customer size.”

Session Recording in XenApp & XenDesktop 7.8 Ensures Compliance & Productivity

“Session Recording, available in XenApp and XenDesktop Platinum Editions, allows administrators to record on-screen user session activity and play it back at a later time as required. It has been available for server-based desktops and published applications for some time, and now, VDI desktops are supported as well. Policy control and notification options provide flexibility to meet environment requirements and regulations.”

Configuring XenMobile Unified Gateway

“Where remote users needed to access their SaaS and Enterprise apps along with XenApp/XenDesktop published apps via their web browser, they used to launch the NetScaler Gateway’s URL. Post authentication if the AppController was integrated with StoreFront, they get access to apps published by AppController and StoreFront. Unified Gateway is integrated into NetScaler 11.0 release. When configured, Unified Gateway provides consolidation via one URL to access multiple secured services.”

Updated Guidance on PVS Ports and Threads

“Recently, I had a chance to talk with our PVS Sr. Architect Jeff Pinter-Parsons who led me to believe that we need to reevaluate the details surrounding this leading practice. Per our discussion, PVS is actually not using a standard threading model where each client gets it own port/thread much like a TFTP server does. Instead PVS has a listener for each port that receives a request and dumps it on a port specific thread pool. The threads in the pool process each request, one per thread. If there are more threads than cores, the leftover threads simply block. Adding more threads than CPU logical core is not going to help on performance.”

StoreFront Message Customization

“This is a newer version of a customization I wrote about last year. This version will work with StoreFront 3.0 and up. (Previous version StoreFront 3.0 Message Customization)”

Delete Local User Profile Folders on StoreFront Servers

“As many of you might be aware, the Citrix StoreFront authentication service provides an option for users to change their passwords when they expire. By default, this option is disabled when the authentication service is created, which prevents users from changing their passwords even if the passwords have expired. If you decide to enable this option in Citrix Receiver for Web, keep in mind that StoreFront creates a local user profile to check whether a user’s password is about to expire. Hence, sufficient disk space is required on the local disk of the StoreFront servers.”

Machine Learning with Octoblu and Microsoft Azure

Octoblu enables companies to create IoT services with secure realtime exchange of data. The services are built on open communications and management platform that supports a variety of protocols for physical devices to communicate seamlessly with each other, people, legacy applications, and cloud services. Through public, private, or hybrid clouds users can connect, design, process, and analyze the flow of information. All services have been designed to operate over a robust security and right management architecture.”

Citrix Appdisks How To Guide – Administration Basics and Gotchas

AppDisk, an application layering solution was part of XenApp/XenDesktop 7.8 released in late February this year. This post is not meant to cover the basics of application layering or image management as a whole. You can refer to my blog for a quick overview. My goal in this post is to cover the administrative aspects of application layering using Citrix AppDisks. With that said, lets dig right in!

Creating an AppDisk

There are couple of approaches to creating an AppDisk. The first method is to manually create it at the hypervisor level and then import it within studio. The second approach is to create and assign the AppDisk right from within Studio. You can read more about both approaches here.

To create an AppDisk from within Studio:

Click on the AppDisks node within Studio and then select “Create AppDisk” from the Actions menu.

3-29-2016 11-55-07 PM

On the next screen, select the size of the disk. There are predefined options of 3, 20 or 100 GB or you could pick a custom size. This is also where you would import an existing AppDisk that you have created manually. Keep in mind that on a 3GB AppDisk a good chunk of the space is already used up and you would most likely get less than 1 GB for any new applications you are looking to install into that layer. 

3-29-2016 11-55-53 PM

Next, you select the machine catalog you would use for the VM used to install applications into this AppDisk. Only the compatible options will be made available. For instance in the screenshot below, the only two options available are the NonPersistentVDI catalog and the Win 7 Pool. Reasons are provided as to why the remaining machine catalogs are not made available. Also worth noting that AppDisks can only be assigned random pool catalogs. The machine catalog should have at least one available VM for the AppDisk creation to work.

3-29-2016 11-58-49 PM

Next, give the AppDisk a name and the AppDisk creation process initiates. In my lab, I have seen anywhere from 10 minutes for a 3GB disk and under 20 minutes for a 20GB AppDisk (SATA storage). Creation of these disks on SSD storage was about 30% faster.

Once the AppDisk is created, you can install the required applications.

3-30-2016 11-33-18 AM

Installing Applications within an AppDisk

Within Studio, click on the newly created AppDisk. It should say “Ready to Install Applications”. Under the details section for the AppDisk, the preparation machine information is provided. Within the hypervisor management console, login to the preparation machine and install the required applications.

3-30-2016 11-33-48 AM

 

Once you have installed the applications, within studio, highlight the AppDisk and under the Actions pane, select “Seal AppDisk”. This starts the sealing process and once that is completed, you can run AppDNA compatibility analysis for that AppDisk.

3-30-2016 11-46-40 AM

 

 

3-30-2016 11-47-42 AM

 

Keep in mind that AppDisk Layering cannot be used for applications that have file system drivers and services.  AppDisk does not include application isolation. App-V or Turbo.net provides that functionality. 

Configuring AppDNA and Analyzing an AppDisk for Compatibility Issues

The main differentiator between AppDisk and the other layering technologies out there is the integration with AppDNA for Delivery group compatibility analysis. For instance, once we create an AppDisk we can test compatibility against multiple XenApp Images or a pooled Windows 10 delivery group as examples. This gives the administrator the assurance that the AppDisk is going to work with that delivery group without having to go through extensive regression testing. When you have multiple AppDisks assigned to a delivery group, the AppDNA compatibility analysis also makes sure that all the AppDisks play well together and reorders the AppDIsk assignment if need be based on the analysis. AppDNA integration is a XenApp/XenDesktop Platinum Only feature. 

Before you can run any compatibility analysis, AppDNA needs to be configured within Studio. Click on the AppDNA section under configuration and specify the AppDNA connection settings. Make sure the connection test passes.

3-30-2016 12-00-12 PM

Getting back to where we were in the AppDisk creation, we had just started the sealing process. Once this process is complete, the AppDNA compatibility analysis will automatically kick in if AppDNA connection settings are configured. The compatibility analysis is done against the machine catalog that the preparation machine belongs to. When you assign an AppDisk to a delivery group, compatibility analysis is carried out automatically against that delivery group. If there are multiple AppDisks assigned, then the AppDisks will be reordered if needed based on the analysis. There is an option to “Auto Order” the AppDisks when you assign an AppDisk to a delivery group. 

3-30-2016 11-53-32 AM

 

3-30-2016 12-00-00 PM

To view the report, click on “View Report” next to the AppDisk that you just sealed.

3-30-2016 12-01-10 PM

You can also view the reports from within the AppDNA console under the reports section. Here you have various views including the Application Issues, Application Actions, Issue View and Action View.

3-30-2016 12-58-45 PM

Assigning an AppDisk to a Delivery Group/Groups

To assign an application to a delivery group, click on Delivery Groups within Studio, highlight the Delivery Group that you want to assign the AppDisk to. Under the Actions pane, select “Manage AppDisks”.

3-30-2016 1-01-58 PM

The next screen shows you the currently assigned AppDisks and gives you the ability to add AppDisks. Once you assign your AppDisk, select Auto Order.

3-30-2016 1-02-12 PM

 

 

3-30-2016 1-02-28 PM

 

3-30-2016 1-02-48 PM

 

 

 

You can then select the rollout strategy. You can either reboot all the machines within that Delivery Group immediately or you can assign the AppDisk at the next machine reboot. You can then review the configuration and then click Finish. This initiates an AppDNA compability analysis if you have XenApp or XenDesktop Platinum entitlement and have configured your AppDNA server within Studio.

You can assign an AppDisk created with one OS to delivery groups running other OS’s as well so long as the application is compatible with the target OS. Within my lab, I tested assigning two AppDisks created with a Win2k12 preparation VM to a Win 7 random pool.

To assign an AppDisk to a delivery group, that delivery group needs to using the same storage. To assign an AppDisk to a delivery group on different storage, you would have to create a new VM at the hypervisor level tied to the target storage, clone and associate the AppDisk to the new VM and the reimport it within Studio. I am hoping this process will be simplified in upcoming releases of the product.

3-30-2016 1-03-01 PM

 

3-30-2016 1-03-09 PM

Updating an AppDisk

Currently there is no version management built into AppDisk. This means that each time you need to make an update, you are essentially cloning the existing AppDisk, making changes to it and then reassigning the new AppDisk to the Delivery Groups. It is also worth noting that you CANNOT resize an AppDisk when creating a new version.  

To update an AppDisk, click on the AppDisk node within Studio, highlight the AppDisk you would like to update and select “Create New Version” from the Action pane.

On the next screen, select the Pooled Random machine catalog that you would like to use for the preparation VM. Again a VM needs to be available within that Machine Catalog to perform the update.

You then name the AppDisk with version information and click “Create New Version”. This kicks off the AppDisk creation process as detailed earlier. AppDNA compatibility analysis will be carried out against the preparation VM machine catalog once the new version of the AppDisk is created.

Once the new version is ready, you can assign the AppDisk to the required delivery groups and unassign the old version. This will once again kick off the AppDNA compatibility analysis.

3-30-2016 1-21-46 PM

Resizing an AppDisk

There are no options to resize an AppDisk from within studio today. You would have to resize at the hypervisor level and then reimport and reassign the AppDisk. I am hoping that this is addressed in the near future.

Deleting an AppDisk

To delete an AppDisk within Studio, click on AppDisks, highlight the AppDisk you would like to delete and select “Delete AppDisk” from the Action pane.

3-30-2016 1-39-02 PM

 

Final Thoughts

As I described in my previous blog on Image Management, AppDisk takes us one step further in simplifying Image Management. However App Layering is not a one size fits all solution and should be used in conjunction with other solutions like application isolation and the likes. I am quite impressed with AppDisks for a v1 product. The performance has been very good considering I conducted most of my testing in my lab using SATA storage. However, I do hope that certain administrative tasks (like AppDisk resizing and versioning) improve in the near future.

Citrix released XenApp and XenDesktop 7.8 on 02/25 and with it came numerous feature enhancements. In this post, I want to focus on two of these features as it addresses a major challenge most Citrix administrators have to deal with today.

The Problem

It is safe to say that every enterprise customer that I work with uses Provisioning Services for XenApp and Pooled VDI for all the management, storage and performance benefits. However, a majority of these customers end up having to manage multiple images (sometimes >10). In most cases, applications are locally installed, in a few cases, App-V is used in conjunction with locally installed apps and in rare occassions, SCCM/LANDESK and similar ESD tools are used. For Pooled desktops, its a combination of locally installed apps and apps delivered via XenApp for the most part. On some occassions third party tools are also used. The net result is that multiple dedicated resources spend most of their time updating these images and managing application updates.

So what does XA/XD 7.8 offer to solve this problem?

AppDisk

I constantly have discussions with my customers around how to solve the problem of image management, and it usually boils down to separating the applications from the operating system as far as possible. XA/XD 7.8 introduces AppDisk, which provides the ability to manage your applications independently of the base image. AppDisk falls under application layering, which has been around for a while now. You can add any number of applications to an AppDisk and the AppDisk can then be tied to multiple machines at the same time running different operating systems. So if you are an Enterprise customer that has multiple XenApp silos today due to different business units requiring different applications for instance and have multiple PVS images that you manage for this purpose, you could potentially cut down to one image for each OS and then use AppDisk to layer the applications thereby making management of the images a lot easier. Not only that, application updates become a lot easier and the maintenance windows will reduce significantly. Also if you wanted to replicate your applications across multiple datacenters, it is as easy as copying these appdisks over.

Integration of AppDisk with AppDNA

There are a number of vendors today that offer layering solutions, including some that partner with Citrix. What truly differentiates AppDisk is our integration with AppDNA. When there are multiple layers tied to a delivery group for instance, AppDNA lets the administrator know how a change in one layer could potentially impact compatibility between layers and can reorder the layers if needed. Similarly, AppDNA can also inform the administrator if an AppLayer is incompatible with a specific OS. So if I were to tie the same AppDisk to multiple delivery groups delivering different operating systems, thanks to AppDNA, you can quickly determine if that AppDisk is compatbile with the target OS. This is truly a differentiator and removes a lot of the guess work and manual labor involved in compatibility analysis.

With all that said, layering is not a one size fits all solution for application deployment. There are various challenges. When you use mutiple Appdisks for instance, it is important to understand the dependencies between layers to make sure the layers can working with each other and there are no conflicts. In large environments, there could be hundreds of layers, each layer having a large number of applications. So management could get complex in those cases. Also, AppDisk is not supported on dedicated desktops today. Also important to note that PvD and Appdisk cannot be used together today

App-V Packages

Another key feature in XenApp/XenDesktop 7.8 is the ability to publish App-V packages that are stored in a network share without needing the App-V infrastructure. The process is no different from publishing a natively installed application. You may ask why even go down this path when you could address most use cases directly with AppDisk. There are a couple of reasons. First, AppDisk does not provide application isolation. So, if you require application isolation, perhaps to run multiple versions of the same application for instance, you would need to use a technology like App-V. Secondly, if you already have your desktop teams leveraging App-V to sequence packages, it makes sense to deploy the same packages within your Citrix environment instead of reinventing the wheel.

Final thoughts

Its human nature to be enamored by the latest shiny toy. But in the case of application management, there is no one size fits all solution. But with the XA/XD 7.8 release, there are various options available for packaging and delivering applications thanks to the tools Citrix added. Does that mean the tools we provide will address 100% of the use cases out there? Probably not. We have a number of partners who add further value through their solutions. Fine examples are Liquidware Labs, FSLogix and Unidesk.

I believe that a lot of enterprise deployments, will continue to deploy core applications natively in the base image, either locally installed or using App-V and the likes. However, AppDisk with AppDNA is a great solution to manage business unit specific applications that were silo’d in the past and increased the infrastructure and operational overhead substantially. To conclude, I would highly recommend that you try XenApp/XenDesktop 7.8 in a lab environment and get familiar with AppDisk and App-V package deployment.

 

Step by step guide on configuring the Rasperry Pi to deliver Citrix Apps and Desktops to your End Users!

Why The Raspberry Pi?

In working with my customers over the years, end point management is something most struggle with to this day. Some choose to still provide their end users with fat clients, having to figure out how to manage the operating system and applications while making sure the device is secure. This tends to be a daunting challenge both from an operational and financial perspective. Others choose to leverage thin clients when possible but struggle in deciding what the right device is from a price and functionality pespective. A lot of times, they spend upwards of $500 on these thin clients, which still run a Windows Embedded OS that still needs to be managed and in some ways defeats the purpose of a thin client. While this is not true in every case, I would say that the end point management dillema is one of the biggest factors in virtualization initiatives stalling at my enterprise customers.

Over the past couple of weeks, I have been taking a closer look at the Rapsberry Pi. For those of you not familiar with the Raspberry Pi, I would highly recommend you check this out. While the use cases for the Pi are immense, what peaked my curiosity were recent blogs by Martin Rowan and Trond Eirik Haavarstein around how they leveraged the Pi as a thin client replacement for Citrix workloads.

Now before we go further, its important to understand why this was interest to me. First off, the device can be made highly secure by running stripped down Linux OS. Secondly, a Raspberry Pi 2 costs roughly $35. Tack on a case and adequate storage, the device is still under $50. So if there was a way to effectively deliver Citrix workloads leveraging this device, this would be the cheapest thin client out there! Not to mention a simple support and maintenance strategy, GET A NEW ONE! :)

How Does One Get Started?

I decided to get myself a Raspberry Pi 2 and give it a test run. I ordered the Vilros Raspberry Pi 2 Complete Starter Kit off of Amazon for around $55 (its around $70 now but price fluctuates). I would highly recommend going for a starter kit, either the one I got or the even more popular Canakit as these include everything you’ll need including wi fi adapter, case, hdmi cable, heat sinks, storage, power adapter etc. I also ordered a couple of additional micro SD cards. I wanted to have different OS builds on each of the cards, making it easy for me to showcase different solutions by just switching the micro SD cards on the Pi.

I looked at ThinLinx, Raspian Jessie and the Raspberry Pi Thin Client Project as potential options, but decided to start with ThinLinx and Raspbian Jessie. Before you get started, I highly recommend you read the this blog by Eric on Running Citrix workloads on ThinLinx and this blog by Martin Rowan on configuring and optimizing Citrix Receiver on Raspbian Jessie.

Approach 1: ThinLinx

Lets start with the ThinLinx build. ThinLinx OS (TLXOS) helps make effective thin clients out of old PC’s, Intel Compute Stick, Intel NUC and Raspberry Pi. TLXOS supports various protocols including Citrix HDX, RemoteFX 8.1, RDP. Intel showcased their NUC devices running ThinLinx at Citrix Summit this year. Check out the video. In addition Rachel Berry wrote an excellent blog about how Citrix leveraged Intel NUCs running ThinLinx for our Demos and Labs at Citrix Synergy 2015.

The process is as follows:

  • Go to this website and download the TLXOS Installer for Raspberry Pi.
  • Connect your micro SD card to your PC and run the TLXOS installer. This will format your micro SD card and copy the TLXOS image on the card.
  • From the same website mentioned above, download the ThinLinx Management Software (TMS) and install the software on a windows test machine. This is fairly lightweight software and can run on a VM as well.
  • Insert the micro SD card with TLXOS into the Raspberry PI and start it up.
  • Run the TMS app on your PC, which will detect the PI running TLXOS. You can configure the PI running through the management software.
  • In my case, I used TMS to make sure Citrix HDX is selected under the “Protocol” section. You could also choose “Web” and run in Kiosk mode if you’d like user to connect in that manner. You can also speficy a name for the device, upgrade software on the device, push SSL certs (required if your backend resources are running internal certs) etc.
  • On the PI, specify the Native Receiver URL. You will then be prompted for your credentials. Once thats set, you are good to go! You should see your apps and desktops, which you can then launch.

Video showcasing Citrix on a Raspberry Pi 2 running TLXOS

My Thoughts on the ThinLinx Option.

ThinLinx adds about $10 to the cost of the solution, bringing it to $69 in my case. However that is still a lot cheaper than your main stream thin clients. In addition, you get complete management capabilities which is absolutely necessary in an Enterprise environment. TLXOS was extremely easy to get going and the functionality was superb both for regular compute and for multimedia. The Citrix HDX protocol on TLXOS supports H264 decode upto 30 fps at 1080p resolution. There was no tinkering to get receiver to work. It just worked! I did notice some artifacts with the mouse cursor (as you might notice in the video) but not all the time. Overall I was very pleased with the simplicity of the solution and the overall performance of Citrix Workloads on TLXOS.

Approach 2: Raspbian Jessie

Raspbian OS is based off of Debian Linux. Jessie is the current version. There are two versions available for the PI – a full desktop image and a minimal image. I went with the full image for my tests. The Raspbian Jessie solution that I tested was unmanaged, unlike ThinLinx. So I had to install the OS, install receiver, tweak parameters to optimize performance etc. Nonetheless, the end result was a great performing thin client. I followed Martin Rowan’s blog for the various tweaks. I will try and outline them once again but wanted to call out that the tweaks were from his blog. So here are the steps:

  • Download the Raspbian Jessie full desktop image from this link.
  • Download Win32DiskImager and install on your system
  • Extract the Raspbian Jessie Image from the zip file
  • Connect your micro SD card to your PC
  • Run Win32DiskImager and use the extracted image as your source and the micro SD as your destination. This will format and copy the Raspian Jessie image on the SD card.
  • At this point, remove the SD card from your PC and plug it into the Pi and boot the Pi.
  • Run the following optimization commands in Raspbian Jessie. Once again, read Martin’s blog for more details.
    • Expand Filesystem
      • Run sudo raspi-config and select option “1 Expand Filesystem“. Reboot the Pi.
    • Run sudo raspi-config and select option “4 Wait for Network at Boot“, then select the option for “Slow Wait for network connection before completing boot“.
  • Install Citrix Receiver for ARM
    • Download Citrix Receiver for ARM (ARMHF) from the following link (under Debian packages)
    • Also download the USB Support package (ARMHF)
    • Install the Receiver: sudo gdebi icaclient_13.2.0.322243_armhf.deb
    • Install the USB Support package: sudo gdebi ctxusb_2.5.322243_armhf.deb
    • Further Optimizations (Optional)
      • Increase Frame Buffer – Section 2.1 in Martin’s blog
      • Switch to using libjpeg62-turbo – Section 2.2 in Martin’s blog
      • Disable H264 Graphics – Section 2.3 in Martin’s blog
      • Disable Mulimedia (HDX Mediastream redirection) – Section 2.4 on Martin’s blog.
      • Overclock your Pi – Run raspi-config to overclock your Pi and get some additional juice.
    • Start Receiver and specify URL to connect to your Citrix Storefront server. At this point you will be prompted for credentials.
    • Now you will have access to your desktops and apps.
  • I did run into an issue with Audio being routed over HDMI and not the headphone jack. To switch this back to the headphone jack, follow the instructions here

Thoughts on Raspbian Jessie

My experience so far with Raspbian Jessie has been good. A little more tweaking and hacking as compared to ThinLinx, which worked out of the box. You get to install the latest receiver though. General performance for productivity apps was great and on par with ThinLinx. The boot was a lot faster than ThinLinx (<10 seconds).

Final thoughts based on testing so far

Is the Rasperry Pi a good solution for all use cases at the moment? Probably not. Does it fit a majority of the use cases? I would say so based on the testing so far. There are definitely some gaps, like having a power button perhaps (hopefully in Raspberry Pi 3), multi montor support to name a couple. Another major requirement for most organizations out there is Unified Communications, and in most cases, its Skype For Business. Citrix has excelled in supporting Lync and now Skype for Business in a virtualized environment while offering a native-like user experience with out of band peer to peer communication as far as voice and video traffic goes. Watch this video which compares the native vs optimized user experience side by side. One of the pieces that makes this possible is the Real Time Media Engine (RTME) which is installed on the client. Today, there is no RTME client for the ARM processor. You can still support Sype but all the processing will occur on the backend servers. I am sure an ARM based RTME client is on the list of good to have’s for Citrix and its probably just a matter of time, especially with the rapid popularity of ARM based devices like the Pi and Intel Compute Sticks. Hoping my friend and fellow citrite Scott Lane will work some magic to make this happen :) Read this blog by Chris Fleck on why he believes the Raspberry Pi could totally disrupt the PC industry. I tend to agree with Chris.

Whats Next?

I will soon be testing the Raspberry Pi Thin Client Project, specifically the 1.99 release which has Citrix Receiver 13.3 bundled in. I hope to have a follow up blog on this. On the fun side, I plan to build an Arcade Machine for my kids based on the Pi and perhaps even a media center, although I really love my Roku :) Check out some of the fun projects out there based on the Pi. As always I look forward to everyone’s feedback and do comment if you have ideas on future blog topics.

More soon..

Citrix Unveils Free Cloud-based Service to Migrate VMware Horizon View Customers to Citrix XenApp and XenDesktop

For VMware customers under pressure to improve their app and desktop  experience, gain greater infrastructure flexibility and simplify end user computing management, Citrix is introducing a free cloud-based service to migrate VMware Horizon View virtual app and desktop deployments to XenApp and XenDesktop. Powered by the new Citrix Lifecycle Management Service – now available from Citrix Workspace Cloud – the new service enables administrators to do an in-place migration in less than 15 minutes by easily exporting application and desktop settings from Horizon View into the Citrix app and desktop delivery solution. The creation of the migration service addresses numerous requests Citrix has received to salvage failed, stalled and small VMware VDI deployments.

Citrix Delivers Cloud Simplicity without Sacrificing IT Control

At Synergy, Citrix previewed Citrix Workspace Cloud, showing the first cloud platform that will enable IT to cope with the increasing pressure to provide IT resources on demand to their user community. Citrix Workspace Cloud enables business productivity by providing IT with the fastest and easiest way to manage and securely deliver apps and data from their choice of cloud or hybrid infrastructure. After enabling thousands of channel partners and customers to test-drive the product, and after providing early access to trial customers, Citrix is making Workspace Cloud generally available with service packages available for production deployments.

Citrix Lifecycle Management: A step by step walk through of an automated deployment on ANY cloud! 

Citrix Lifecycle Management (CLM) provides customers and partners alike an orchestration and automation engine that they can use to build an end to end infrastructure that meets industry and their own best practices on ANY cloud.It also helps you manage and monitor the environment as well as conduct operational tasks and upgrades.

What is truly great about this solution is that CLM is not limited to deploying Citrix infrastructure. It can be used to deploy Microsoft infrastructure (AD, SQL etc), partner solutions (Atlantis USX, LoginVSI, Xangati etc) in addition to Citrix infrastructure (XenApp/XenDesktop/Netscaler/Storefront etc). There are various blueprints that are already pre populated and the list will continue to grow. In addition customers and partners can create their own blueprints based on their own best practice. Because blueprints are leveraged, deployments are easily reproducible and error free. For instance, a senior architect could develop a complex blueprint and then once complete, hand off to a junior resource who could very easily deploy the same blueprint anywhere he pleases with consistent results. From a partner perspective, this makes deployment of solutions extremely simple and consulting engagements and proof of concepts should end up being much more successful and predictable.

Citrix Named a Leader in the Magic Quadrant for Enterprise File Synchronization and Sharing Market

Citrix Offers Digital Badges to Distinguish Certified Citrix Professionals

Citrix Education continues to be a leader in the IT certification space, bringing to market new and innovative ways to measure relevant and in-demand skills, while connecting talents with opportunities and businesses with the talents they need. Our track record dates back to 2003 when we debuted one of the most innovative hands-on certification exams: the CCIA 612 lab exam. Today, we take another step forward by offering our certification holders with a new, in-demand and highly valuable service for free.

We are pleased to announce the official launch of the Citrix certification digital badging initiative, a project we piloted with success earlier this year.

Delivering Cloud Workspaces: Choice Matters

Today, we must demand of our software vendors that they support true, multi-platform hybrid clouds. And conversely, we must question why an ISV like VMware would claim all you need is “one cloud” Why? Citrix believes customers and partners want to support any application, available on any device, delivered from any cloud or even any infrastructure. After all, the ability to support multiple cloud  fulfills on the promise of hybrid cloud and multicloud computing. And at Citrix, this degree of choice and flexibility is core to our philosophy.

Starting with NetScaler 10.5 Build 51.1017.e+, you can now can create and bind Content Switching Policies directly to NetScaler Gateway VServers. Connections destined for the Gateway are terminated and processed as normal, but before any actions are invoked on the session, the policy engine checks to see if any Content Switching policies are bound which may apply. If the conditions defined in the policy are satisfied, connections are sent to the target Load Balancing VServers defined in the applicable Content Switching Policy action.

How to Enable/Disable HDX Session Idle & Disconnect Timers on Linux VDA

The Linux VDA supports idle timers for controlling how long a HDX session can remain idle before being disconnected, and disconnect timers for controlling how long a session can remain disconnected before being terminated. When an idle timer expires for a session, due to no user interaction with that session, the user will receive a warning dialog informing them that they are going to be disconnected in five minutes.These timers are not enabled by default, implying sessions can remain in the idle or disconnected state indefinitely. We’re going to talk about how to enable, configure and disable idle/disconnect timers on the Linux VDA.

Radically Simplify Management of Citrix Workloads and Enterprise Application Lifecycles

IT administrators are realizing that application deployments are getting more complex and error-prone than ever before. Additionally, the deployment of Citrix workloads and enterprise applications is only the first step in the lifecycle of applications. Once the workloads are deployed, IT administrators must continuously monitor the health of the workloads to ensure they are running at optimum performance, can scale efficiently to meet changing demands and are always available to end users even in case of application component or environment failures. What if there were an integrated application service lifecycle management solution that empowers IT to streamline design, deployment and management of a broad array of application workloads across hypervisor or cloud environments, all through a single integrated console? Now there is! We are excited to announce the General Availability of Citrix Lifecycle Management!

Citrix Lifecycle Management: A step by step walk through of an automated deployment on ANY cloud!

1

Citrix released Citrix Workspace Cloud (CWC) earlier this week. Most people I talk to agree that CWC is one of the most innovative solutions in the industry right now. You can read more about my thoughts on CWC here.

In this post, I want to focus on one of the components of CWC namely Citrix Lifecycle Management (CLM). CLM provides customers and partners alike an orchestration and automation engine that they can use to build an end to end infrastructure that meets industry and their own best practices on ANY cloud.It also helps you manage and monitor the environment as well as conduct operational tasks and upgrades.

What is truly great about this solution is that CLM is not limited to deploying Citrix infrastructure. It can be used to deploy Microsoft infrastructure (AD, SQL etc), partner solutions (Atlantis USX, LoginVSI, Xangati etc) in addition to Citrix infrastructure (XenApp/XenDesktop/Netscaler/Storefront etc). There are various blueprints that are already pre populated and the list will continue to grow. In addition customers and partners can create their own blueprints based on their own best practice. Because blueprints are leveraged, deployments are easily reproducible and error free. For instance, a senior architect could develop a complex blueprint and then once complete, hand off to a junior resource who could very easily deploy the same blueprint anywhere he pleases with consistent results. From a partner perspective, this makes deployment of solutions extremely simple and consulting engagements and proof of concepts should end up being much more successful and predictable.

In the next part of the blog, I would like to walk through an on premises deployment of an on premises XenDesktop POC that I built leveraging CLM.

Once you log into CLM. The first thing you want to do is to go ahead and define your resource zones. Today CLM supports the resource zones listed below. In my case, I leveraged an on premises XenServer 6.5 host.

Resource Zones

The next step in the process is to install the CLM connector on Windows Server 2012 R2 server. This is similar to a CWC deployment. The connector is what facilitates communication between the CLM orchestration engine and your resource zone. Once the connector is installed, you define the connection details for your host and you are all set. As you can see from the screenshots below, I defined two resource zones in my lab, both XenServers.

Screen Shot 2015-08-25 at 9.35.06 AM

Now that we have our resource zones, the next step is to go through the blueprint catalog and pick the one we want to deploy. As mentioned earlier, there is a pretty good list of blueprints already available and this list will continue to grow over time. Once you know the blueprint you’d like to use, you click the “+” symbol to add the blueprint to your library.

 

blueprint catalog For the purposes of my test, I used the XenApp and XenDesktop Proof of Concept Blueprint and added it to my library. The blueprints that I choose will show up under the “Design and Deploy” tab. Within “Design and Deploy” you now click on “Actions” next to the selected blueprint and choose “Deploy”. Note that you have the ability to edit, clone or share the blueprint if you want to. This will allow you to customize the blueprint as you please.

Design and Deploy

Once you hit “Deploy”, you are provided a description of the blueprint along with the various infrastructure components. After reviewing the details, click “Start Deployment Setup” and give the deployment a name. You can also choose an existing deployment profile if you’ve gone through this process before.

Deployment Overview

Deployment Name
As part of the template I chose, I have some additional options like providing a KMS Server address, configure a Netscaler, create a server VDI instance etc. I have stuck to the defaults for the test. I also specified the resource zone that I would like the solution to be deployed on.

Deployment-2

Next, you’ll see a pre deployment checklist based on the resource zone you selected. Review this carefully!! One of the key pieces to having this work properly is to make sure you have a Windows Server 2012 R2 template ready on your XS host. Below are some things to keep in mind:

  • Make sure the image is sysprepped with the /generalize /shutdown /unattend options. Use the unattend file to provide login credentials among other things. A sample unattend file can be found here.
  • Make sure RDP access is enabled in the template
  • Make sure the Windows Firewall allows outbound connections on port 443
  • Install the latest XenServer tools and reboot the machine as many times as needed to ensure the process is complete.

Pre Deployment checklist

On the next screen, hit edit on each of the VMs and define the various parameters. Some of the key things you need to make sure include selecting the right VM template, NIC and providing the correct credentials. I have included screenshots for one of the VMs below.

vm1

vm2

vm3

vm4

vm5

 

After going through the configuration for each of the VM’s hit “Next” and provide additional configuration parameters in relation to the domain, XenDesktop and computer names. You can also import a config file to fill these parameters. Once complete, give the deployment profile a name and description.

Additional Parametes

profile name

On the next screen, review the configuration and hit “Deploy”. This starts the deployment process. If you look at your hypervisor host you will notice that VM’s being to get created.

Final Deploy Screen

Next click on the “Manage” tab and click on your current deployment to check the progress of the deployment. You will obtain a detailed breakdown of each step of the process.

Deployment progress

Deployment progress2You will also be notified via email as each VM is successfully created and also when the whole deployment is complete.

email1

 

email2

The entire process in my case took about 2 hours on really old hardware. I will be redoing this test in the coming weeks on much faster SSD drives to see how much time I can shave off.

In addition to allowing you to deploy solutions, CLM also has inbuilt monitoring and alerting. You get a snapshot of how the VMs are performing and you can also set thresholds for the alerts.

Monitoring

CLM also allows you to define operational tasks such as installing updates, running certain scripts etc right from within the CLM engine. These tasks can also be scheduled.

OPerations

You can also define rules for dynamically tearing down, scaling up and also failover/fallback rules with the CLM engine. In the future I plan to play around with these a little more.

Scale and Redundancy

Final Thoughts

I am truly excited about the potential this platform holds and the value it brings to customers and partners. CLM helps automate the deployment, manage and monitor the environment and tear down whether you want to deploy just within your datacenter, a public cloud, private cloud or a hybrid cloud. In other words it helps through the entire lifecycle of a deployment. The simplicity of the platform along with the blueprints ensures that you dont need to have expert level skills on any of the solutions to deploy the blueprints. I would encourage everyone to try it out. I am sure if you do, you will end up being just as impressed as I am today!

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Geo Maps for HDX Insight (NS Insight Center 11) – Overview and Configuration

NS Insight Center 11 was released earlier this month, and with this release Geo Maps is now available for HDX Insight. It was earlier available for Web Insight only. For those of you not familiar with HDX Insight, it is a tool from Citrix that provides end to end visibility from an end user experience perspective for ICA connections that are proxied through the Netscaler. So for instance, if a user reported a slow Citrix session, HDX Insight would help you determine if it is a client side issue (workstation/ISP etc), server issue, application issue, network issue etc. It also provides breakdown on how the bandwidth consumption within the ICA channel (printing/usb/screescrapes). More information on HDX Insight can be found here.

2015-07-28_15-42-17

With the 11.x release of NS Insight center, a new feature called Geo Maps has been added to HDX Insight. Geo maps as the name suggests provides a pictoral representation of all the locations from where users are connecting from. By click on any location, you get a summary of the end user experience metrics for that region. This helps you identify performance issues isolated to a specific region quite easily. In addition you can also quickly determine if users are connecting from regions that you dont expect and thereby potentially mitigate a security threat. Geo Maps is an extremely neat addition to HDX Insight and a feature that will greatly benefit customers, specially customers with employees spread across the globe!
