I’ll Make It Up To You (Imagine Dragons Cover)

Great to finally spend a Friday night making music after what seems like forever. This is a song from the album “Evolve” by Imagine Dragons. As always I have added a few layers including harmonies. First time I am recording using the SM7B. Also used my Mininova on this one. Can you spot it?

Sites vs Zones in XenApp/XenDesktop 7.x – Design Considerations When Choosing Between The Two

Introduction

Zones, a key design element that administrators and architects have learned to love in XenApp 6.5 was reintroduced in Xenapp and XenDesktop 7.7 FMA architecture. Prior to 7.7, building multiple sites was generally recommended when spanning multiple data centers or regions but now customers  now have the option of leveraging Zones. While Zones is a potential option, it might not always be the right option based on your situation. In this post, my goal is to review basic concepts around Sites and Zones and dig into design considerations to help choose between the two.

Primer on Sites and Zones

Sites

A site is what you define when you deploy XenApp or XenDesktop under the FMA architecture. It acts as a logical boundary with all objects defined being part of that site. It is also an administrative boundary. Each site has one or more delivery controllers and requires its own site configuration database. A site always have one primary zone defined by default. Sites can span multiple data centers and regions but there are a number of factors that need to be taken into consideration and we will review these a little later.

Zones

Zones are defined within a site to keep applications and desktops close to the user location while also simplifying administration by leveraging a single instance of Studio, Director and configuration database regardless of the number of zones. With zones, users in remote regions can get to their resources without having to traverse the WAN.

There are two types of zones – Primary zones and Satellite zones. Primary zones typically have two or more controllers and have the site configuration database locally whereas satellite zones can have a single controller or more. While similar, zones in the new FMA architecture in 7.x is not the same as XenApp 6.5. For instance, the concept of a zone data collector no longer exists.

With the introduction of Zone preference in conjunction with Optimal Gateway Routing, users can be homed to a specific zone when accessing their apps and desktops based on predefined conditions and rules. This greatly improves the user experience. Disaster recovery can also be handled intelligently.

For detailed information on Zones and Zone preference I would recommend you review the official documentation. Carl Stalhood has a very good blog on this topic as well.

There is also a great overview of Zone Preference in the XenDesktop 7.11 Master Class starting at the 58 minute mark.

When to use Sites

While zones simplifies overall administrative overheard and potentially infrastructure requirements, leveraging sites is a more prudent choice in certain scenarios. Lets look into these:

Latency

Latency will impact user performance. Latency and concurrent user requests should be taken into consideration and tested before deciding to use zones. See the chart above for different scenarios tested. There are two great blogs, one by Chris Gilbert and another by William Charnell on how latency affects brokering performance from satellite zones in XA/XD 7.7 where they collect metrics under various latency conditions. Definitely worth a read. However these metrics have improved significantly in 7.11 and above. In fact, 250 ms latency, XenApp and XenDesktop 7.11 outperforms the 7.7 code at 90 ms. With 7.11 or later, users experience quicker brokering of resources, even with latency between a broker and the SQL server. The official citrix documentation covers latency and the impact on zones, registration storm impact and how this can be tuned in great detail.

Fault Domains

When we talk about large deployments with greater than 5000 users, it is best practice to break the environment down into smaller PODs. This helps split the enviroment into multiple fault domains such that when any of the pods are affected, only a small set of users are impacted if any. Even when all users connect in to a single datacenter, it is still beneficial to break the infrastructure down to multiple sites and PODs. Here are the slides from a great session at Synergy 2015 that covered the benefits of a POD based architecture. This blog is also worth a read.

Administrative Boundaries/Regulatory Compliance

For environments that require complete administrative isolation between different regions or business units, going with separate sites is recommended. While Role Based Access Control is available, it does not meet the needs of every customer. In addition I have worked with customers that have gone with multiple sites so as to isolate environments to meet compliance requirements such as PCI or regulated environments where upgrades are not as frequent.

While multiple sites requires additional infrastructure, the resources from the various PODs can be aggregated from a user access perspective. Monitoring and troubleshooting can also be simplified as Director can manage multiple sites. A number of the tasks can also be automated by leveraging script. Image management can be greatly simplified by leveraging PVS.

When to use Zones

When designing a XenApp/XenDesktop infrastructure for an environment with multiple datacenters with latency being a non factor (within acceptable limits), zones can certainly be an option. The number of users per satellite zone can play a factor when making that determination as discussed earlier. Fault tolerance should also be taken into account as all the zones share one common site configuration database and connectivity issues could impact all the users. The resources that users connect to can be controlled based on zone preference and failover. 

Using a combination of Sites and Zones is also an option. For instance if a customer environment is spread across the globe but also has multiple datacenters within each region, they could use Sites for each region and the leverage Zones for the datacenters within each region assuming low latency between the datacenters. This would help reduce the overall complexity and administrative overheard when compared to deploying a site per datacenter.

From The Field

Here is some feedback from Jason Samuel, one of our CTP‘s based on his experience.

“Most of my customers completed their migrations from 6.5 to 7.x when either zones weren’t available in FMA yet or was still new.  They went with a site per data center.  My bigger customers embraced localized pods within each datacenter itself.  This is often self contained pods built on HCI as the backend.  Application and image management is controlled through PowerShell scripts to help with administration of multiple sites.  Since these customers have been using this model for a few years now and it is a mature process for them, they continue with this approach.  My customers that are doing greenfield 7.x deployments are the ones that really consider zones vs. doing individual sites.”

Ryan Mcclure, Senior Architect at Citrix Systems had this to say: 

“So armed with this data and information, what should you do? Stick to multiple sites? Design with zones wherever possible? Some scenarios just beg for zones, while others are obvious use cases for sites/pods, but more commonly, both are technically viable and it is a matter of weighing the pros and cons. If your workload is mission critical and your deployment lives in one or two datacenters, multiple sites are probably a good option for you. They provide additional fault tolerance, shrink failure domains and increase flexibility during upgrades. If, on the other hand, you have a number of semi-well connected locations where application back-ends reside, one site per location may prove prohibitive from an administrative perspective. These sorts of deployments are where zones should really be considered. The combination of sites and zones also shouldn’t be overlooked. The geographic distribution cited above is one example, but sites and zones can also be combined to strike a balance between manageability and availability. Rather than all VDAs in a zone mapping to a single primary site, multiple primary sites can be deployed.

When the decision isn’t obvious, our most successful customers ask the same question:

“What are other customers in similar situations doing?”

The strategy around sites and zones definitely isn’t one size fits all, but up until now, most of our large enterprise customers have gravitated towards separate sites. Many do so based on their desire to shrink failure domains and minimize risk wherever possible. You may have even heard recommendations to skip zones because sites have been available longer in the FMA world. At the time, this recommendation may have made sense, but the IT space is as dynamic as ever and leading practices need to be updated with the times. Over the last few months, this trend around steering clear of zones has started to shift, and more customers are taking a hard look at how zones can help simplify environment management. In most scenarios, zones shouldn’t be viewed as a total replacement for sites, but if your deployment can be simplified and/or management streamlined by implementing zones where the make sense, now is the time to give them a good look.”

Final Thoughts

Zones in XenApp/XenDesktop 7.9+ is a welcome addition and offers greater flexibility when planning out deployments. However, it is not necessarily the solution for every use case as discussed above. Latency, number of users/location, concurrent logins etc need to be carefully considered before deciding whether to go with multiple sites or leverage zones instead.

Is Samsung Chromebook Plus The Perfect Chromebook?

Over the past couple of years I’ve been collecting a lot of chromebooks. As of the 13th of Feb, I now own 6, mostly Acer and Samsung devices. As much as I love the concept of a low cost, ultra portable and secure thin client with excellent battery life & then leveraging Citrix for my enterprise apps, it always felt like there was something missing. Some of the common complaints were display resolution, build quality, lack of offline access and lack of a good touch screen model under $500.

Needless to say I was extremely intrigued when Samsung announced the 12 inch Chromebook Plus and the price point. I pre-ordered the device and got mine earlier this week. My experience so far has been terrific. Lets look into why I feel this device is close to perfect.

Design

The Samsung Chromebook Pro is a  12.3-inch laptop that also converts into a tablet. It is powered by an OP1 Hexa-core (Dual A72, Quad A53) ARM processor with 4GB of RAM and 32GB of storage. It comes with two USB Type-C ports and a microSD slot. It has various display modes, very similar to the Lenovo Yoga. It has a full metal design that weighs just 2.4 pounds. It comes with a stylus that pops out of the right side of the system, letting you take notes with Google Keep and other apps and smart enough to recognize characters, allowing you to search through your handwritten notes afterwords.

Display Resolution

Resolution has been one of my biggest gripes with chromebooks so far. And boy does this device address that issue. The Chromebook pro comes with a quad HD (2400 x 1600) pixel screen made with Gorilla Glass 3. with a 3:2 aspect ratio. The high resolution means my Citrix VDI instance looks absolutely spectacular on this device. Lots of real estate too!

Battery Time

Based on my testing so far, the battery time of the Chromebook Plus is on par every other chromebook I own. I’m getting approximately 9-10 hrs. Keep in mind that the resolution for this device is also one of the best. So that the battery time extremely impressive.

Android Apps!

This to me is a GAME CHANGER!! As you know, Google announced support for Android apps on chromebooks last yr. The challenge was that just a handful of devices were actually supported, and even among the ones where it was supported there was only one that had a touch screen. Personally I believe Android app support is pointless if there is no touch screen. Thankfully the Chromebook plus does have one! The combination of android app support, great resolution and touch screen makes it the perfect device. I now have a number of key productivity apps, many of which I can use offline. Some of my favorites so far are Citrix Secure Mail, Secure Web, Sharefile (Enterprise File Share and Sync), Slack and Skype for Business to name a few.

Touch Screen

The touch screen is extremely responsive. No lags whatsoever. Works great in tablet mode. Also great when using Android apps. All chromebooks moving forward need to be touch enabled IMHO. You cannot effectively use Android apps without touch!

Stylus!

The Chromebook Plus comes with a pressure sensitive stylus that is on par with others like the Surfacebook. Is it perfect? No. But its quite good. I can totally see myself using this device to do a white board or sketch a design while I am at customers. Very handy!!

Final Thoughts

Today was my first day out on the road with just the chromebook pro. I honestly did not miss my XPS 13. I accessed my Citrix VDI instance the entire time and the experience has never been this good on any of the other chromebooks I own. I also used a number of android apps including Skype for Business, Sharefile, Secure Web and others. The combination of VDI, chrome browser and native mobile apps is quite amazing. I used the the system for around 5 hrs and did not run into any issues during that time.

At $449, this device is a steal! If you are looking for a chromebook today, this should be in the list of favs! If I were to change one thing, I would add more memory to this device. Android apps can eat up memory fast!

Kudos to Samsung for a job well done!

Citrix acquires Unidesk: Here’s why customers should care!

Application layering has been a hot topic in the End User Computing space, specially the last 24 months or so. Layering allows you to decouple applications or groups of applications form the underlying operating system thereby enabling you to manage them indepedently. There are quite a few players in this space including AppVolumes by VMware and FlexApp by Liquidware Labs and Citrix’s AppDisk to name a few. But there is no arguing that Unidesk has been around the longest and has the most mature and comprehensive solution.

With today’s announcement from Citrix around the acquisition of Unidesk, customers have even more flexibility in terms of how applications and workspaces are delivered to their end users whether the workloads are running on premises or in the cloud.

Before we get into the key benefits of Unidesk and why this acquisition adds tremendous value, its important to understand some of the challenges that Citrix customers face. A good place to start is this survey that Unidesk conducted.

The Problem At Hand

1. Image Management – Today both PVS and MCS customers have to maintain multiple images. Larger environments sometimes manage and maintain over 10 images on a day to day basis. One of the reasons for this is business units needing one off applications leading to various silos. The administrative overheard involved in maintaining the images sometimes leads to needing dedicated resources who solely focus on image updates, testing and deployment.

2. Pooled desktops and assigning layers at runtime – Most Citrix customers are forced to use persistent desktops for certain use cases today due to users needing different sets of applications. If there was a way to decouple applications from the OS and deliver applications at login dynamically based on user privileges, then the same pool of desktops can be used for multiple use cases thereby reducing infrastructure costs and operating costs.

3. As customers move workloads to the cloud, there are new challenges that surface when it comes to image management. These need to be addressed in order to reduce cost, improve performance and thereby increase cloud adoption.

4. Not every application can be delivered via XenApp. Some applications need to be installed locally. App-V has been an alternate technology that a number of customers use but many still like to have the ability to install these locally.

5. While AppDisk provided layering, there were various limitations including the inability to attach layers at run time and the inability to use layers with persistent desktops. Appdisk also lacks true version management and rollback.

How the Unidesk acquisition helps address these issues

1. Unidesk already has a large number of Citrix customers and tight integration with both XenApp andXenDesktop. They are a proven technology at scale, a preferred MS partner for application and image management, and well regarded in the partner community.

2. Unidesk has connectors for PVS and MCS thereby simplifying application delivery and eliminating the need to manage and maintain multiple images.

3. Unidesk provides flexibility in terms of how the layers are delivered either at pre-boot or  and dynamically delivering apps into running session hosts without reboot. Unidesk has a feature called Elastic Layering that allows for layers to be attached at run time. So in a XenApp environment for instance, since applications are attached at run time, different users groups can be assigned different applications while connecting to the same server. This eliminates the need for silos.

4. Application compatibility is no longer a concern as Unidesk supports layering applications that have drivers and system service dependency and even apps that run while users are logged out.

5. Unidesk supports layering for persistent desktops in addition to XenApp and pooled desktops thereby addressing every use case. Also persistent layers can be assigned to users even while using XenApp. This allows administrators to provide users a more cost effective VDI option to their end users with persistence based off of XenApp.

6. Full Lifecycle Management of layers across your environment with version control, rollback etc.

7. Unidesk’s approach to layering is fundamentally different. A layer is assigned per application. Administrators the have the ability to create a profile so to speak consisting of the various layers for a user group. These layers are then combined into a single vhd that is then attached at boot or at run time depending on the assignment. When compared to other layering solutions since the number of vhd’s mounted is minimized, performance is greatly improved and login times reduced.

7. Cloud adoption has increased steadily over the past couple of years and customers are more inclined than ever to start moving workloads to public clouds, especially MS Azure. The Azure connector from Unidesk simplifies image management in the cloud. Layered Images can be assigned to different Azure collections. In addition all image collections can be updated by patching the OS and app layers only once. The Unidesk applicance can also run in Azure and is available via the Azure Marketplace. When you combine Citrix Cloud with Unidesk, there is definitely a better story now to be told around deploying and managing VDI workloads in Azure.

Final Thoughts

The Unidesk acquisition along with our recent acquisition of Norkskale helps customers further reduce infrastructure costs while increasing operational efficiencies and guaranteeing the most optimal end user experience. For customers running VDI in cloud or considering the move, Unidesk is a great new addition and will simplify image management. Citrix’s position as the industry leader in End User Computing is further solidified.

 

 

How to enable Local Host Cache in XenApp/XenDesktop 7.12

Local Host Cache (LHC), which was a key feature of the IMA architecture in XenApp 6.5 and earlier was reintroduced for the first time in the FMA based XenApp/XenDesktop 7.12 release.   You can learn more about LHC in detail in my previous blog on the topic.

Prior to 7.12, users were able to access resources (with some caveats) while experiencing site database loss using a feature known as Connection Leasing. When upgrading to 7.12 from an earlier release with Connection Leasing enabled, LHC is disabled by default.

To enable LHC run the following powershell command on the upgraded broker.

Set-BrokerSite -LocalHostCacheEnabled $true -ConnectionLeasingEnabled $false

The above command, enables Local Host Cache and disables Connection Leasing.

The Get-Brokersite cmdlet provides the current state of Local Host Cache (whether its enabled or disabled)

To disable Local Host Cache and enable Connection Leasing, run the following command:

Set-BrokerSite -LocalHostCacheEnabled $false -ConnectionLeasingEnabled $true

XenApp/XenDesktop 7.12 Local Host Cache Explained

With the release of XenApp and XenDesktop 7.12 Citrix brought back one of the most requested features from the XenApp 6.x days – The Local Host Cache (LHC). For those of you new to this term, it essentially provided a way for users to connect to their XA/XD published resources while the SQL based database is down but keeping a local cache on the XenApp servers themselves. LHC now replaces Connection Leasing in 7.x as the primary mechanism to allow connection brokering operations when database connectivity to the site database is disrupted. In this post, my goal is to dig into the architecture of Local Host Cache in 7.12 and how it works.

Architecture:

lhc-architecture

 

The above diagram from Citrix Documentation shows the architectural components that make up the Local Host Cache. The feature is disabled out of the box when XA/XD 7.12 is installed. If you are upgrading from a previous version LHC will be disabled under certain conditions. See the table below for further details.

screenshot-2017-01-01-at-1-10-18-am

With LHC, users can connect to Apps and Desktops that they have previously not connected to. This was not possible with Connection Leasing where users could only connect to resources that they had previously connected to.

Every broker now has three new services. The primary broker service, the secondary broker service and the configuration sync service.

LHC sychronization during normal operation and central database connectivity is not affected

  • During normal operations, the primary broker service communicates with the site database while the secondary broker service remains idle. The CSS makes sure the local db on each of the controllers is synchronized periodially.
  • Primary broker service accepts connection requests from Storefront, then communicates with Site DB and provides users access to VDAs registered with the controller and that they request access to.
  • Every 2 minutes, a check is made to see if there have been any changes to the primary broker config.
  • If a change is detected, then the primary broker uses the Citrix Config Synchronizer Service (CSS) to copy configuration to a secondary broker. This is not an incremental copy but a full copy from the primary broker to the secondary broker.
  • Secondary broker then imports the configuration to a local SQL Server Express database on the controller.
  • Once the config is copied the CSS service confirms that the config on the secondary broker matches the config on the primary broker.
  • Local DB on the secondary broker is recreated each time a config change is detected on the primary broker (checked in 2 minute intervals)
  • Secondary broker runs as a Windows service called Citrix High Availability Service

What happens when there is an outage and database connectivity is lost

  • During an outage, the primary broker can no longer connect to the site database and stops accepting connections.
  • Primary broker instructs secondary broker to start listening for and processing connection requests. An election process ensues to determine which controller takes over the secondary broker role. There can only be one secondary broker accepting connections during a site db outage.
  • When the VDAs start communicating with the secondary broker, a re-registration process is triggered and the secondary broker gets current session information about the VDA.
  • During the outage period, the primary broker continues to monitor the connection to the site database and when connectivity is restored, it instructs the secondary broker to stop listening for connections and the primary broker resumes brokering connections thereby restoring normal operations.
  • When a VDA communicates with the primary broker after it has taken over brokering, a re-registration is triggered.
  • The secondary broker removes all VDA registration info during the outage and continues checking for config updates on the principal broker every 2 minutes and updating its LHC when changes are detected.
  • If an outage occurs during an LHC sychronization, the current import is discarded and the last successful imported config is used.
  • It is important to note that during an outage, only one active secondary broker is available. So from a scalability perspective this could be a limitation. The secondary broker as mentioned earlier is chosen based on an election mechanism.

Local Host Cache and Citrix Cloud

  • If you are currently leveraging Citrix Cloud for your XA/XD control plane, the LHC functionality ensures that connectivity loss to the control plane does not impact users from accessing their resources.
  • LHC synchronization occurs the same way as it would in an on premises XA/XD deployment and the config changes are synchronized from the Citrix cloud via the Cloud connector.
  • To provide fault tolerance when connectivity to the Citrix cloud is lost altogether due to a WAN link failure, Citrix Storefront and potentially Netscaler would need to be on premises.

Local Host Cache Restrictions

  • You cannot run Studio and Powershell Cmdlets when LHC is active and site database connectivity is down.
  • Site configuration changes cannot be made when the connectivity to the central database is unavailable. This is very similar to the IMA based LHC implementation in XenApp 6.x
  • New machines cannot be provisioned as hypervisor interaction is not possible when LHC is operational.
  • Users cannot be assigned new resources during the site database connectivity outage.
  • Machines with a “Shut down after use” configuration will be placed in maintenance mode when LHC is operational

Troubleshooting

The two main tools to troubleshoot LHC are the Windows Event Logs and CDF traces.

  • The Config Sync Service logs events in the Windows Event logs in relation to LHC synchronization. If no config changes occur during the 2 minute intervals, no events are logged. If CSS receives a config change, the event is logged with event id 503. If the update to the secondary broker is successful, the event is logged with event id 504. If the update fails, the event is logged with event id 505
  • When the secondary broker takes over during an outage, event log entries are made indicating that the Citrix High Availability Service has started handling brokering. Once services are restored, you would see logs indicating that the Citrix High Availability service has stopped brokering. There will also be events related to secondary broker election. Event IDs include 3502, 3503,3504 and 3505. When Citrix Cloud is in play, XA/XD proxy log events are present. CDF traces can also be used for advanced troubleshooting.

Enabling Local Host Cache After Upgrading

Local Host Cache is not enabled by default when upgrading from an earlier version of XenApp and XenDesktop 7.x. I have written a blog on how to enable LHC after an upgrade.

Unified, Focused: Worx Apps Are Changing to XenMobile Apps

In Q4 of this year, we will be consolidating the number of XenMobile sub-brands by replacing “Worx” with “Secure.” Worx apps will undergo a name change only. The apps will look the same and function the same. This change in naming will not require users to re-enroll their devices or update the XenMobile Server. During the regular application update process, end-users will receive the newly named app, but all application data and workflows will remain exactly as they were before.

Citrix SCOM Management Pack for ShareFile is Here!

Citrix XenServer Supports Microsoft Plans for Enhanced Virtualization Security

Today, Microsoft announced their intent to extend their Server Virtualization Validation Program (SVVP) with an Additional Qualification for third party hypervisors, such as Citrix XenServer, to support some Windows Server 2016 virtualization-based security features (VBS), notably Credential Guard (CG) and Device Guard (DG). Windows Server VMs running on SVVP validated platforms will be able to leverage the new VBS capabilities to strengthen the isolation of a number of security-sensitive components and deliver enhanced security for Windows applications and desktops.

Citrix wins virtual desktop interface shootout

Virtual Desktop Interface is becoming easier to do, with potentially killer graphics, reasonable port virtualization, fine-grained administrative control, and with potential hosts other than Windows.

While Citrix XenDesktop/XenApp remains the one to beat, two other VDI platforms we tested, Ericom Connect Enterprise and Parallels Remote Application Server, can provide for the publishing of diverse applications to desktops, while following “the rules” regarding resource accessibility and security.

In testing, we found Citrix leads the pack in terms of overall flexibility, although its vast feature sets can increase support burdens. If price-be-damned and you really want the venerable Full Meal Deal, it’s Citrix XenDesktop/XenApp Enterprise. We found it has almost everything you could ask for in a VDI product.

Is your security awareness training program working?

Employees at Axe Investment, the fictional firm of biollionaire Bobby Axelrod in Showtimes new series, Billions, were downright angry when they learned that surprise SEC raid was only a test. Axelrod, though, found the mock raid fruitful as it revealed the internal weak links of his organization.

These are metrics that enterprises should be using to evaluate the success of their security awareness programs. In order for awareness training to work, it has to keep everyone in the enterprise, well, aware.

Minimize Windows 10 migration headaches by freeing data from devices

Operating system migrations require detailed planning, as every part of the end-user computing “stack” – hardware, applications, data, and user profiles — needs to be assessed before proceeding. From an organizational productivity standpoint, maintaining the availability of the data people need to do their jobs is a top concern.

How to support Microsoft’s Skype for Business tool on virtual desktops

Microsoft was sluggish in providing a comprehensive enterprise unified communications (UC) product organizations could integrate into a virtual desktop deployment. Virtualization was always an afterthought with Microsoft’s Lync messaging platform, the predecessor to the Skype for Business tool before the company acquired Skype in 2011.

Now, the partnership between Citrix and Microsoft has spawned the HDX RealTime Optimization Pack 2.0, which puts the virtual desktop on par with its physical counterpart when it comes to UC support.

The reality is, in an enterprise environment, IoT will be much more complex than the individual smart device/smart thing relationship. It gets back to Tim O’Reilly’s point about systems. When we started talking IoT initiatives nearly two years ago, we found most people were not excited to talk about IoT as it related to a new sensor, device or gadget. Instead, they were intrigued when you talked about the potential for IoT to help solve complex business problems. As organizations become increasingly digital in all aspects of their business, new challenges in managing the connections, devices and applications that make up their digital business arise. This is especially relevant as enterprise applications evolve to be a collection of services and interactions spread across the cloud, on-premises systems and devices/sensors/things.

Why Citrix Is Better than VMware in Desktop Virtualization

Offerings that have to interoperate are always better between companies that cooperate than companies that don’t. And firms at war with each other seldom are successful with joint efforts. Often joint efforts between firms that actually want to work together fail due simply to cultural difference.

What gives Citrix the sustainable advantage is not only the fact it has a tighter relationship with Microsoft, but—because it appears to realize that it has to do most of the heavy lifting to maintain the relationship, there is none of the typical finger-pointing between the firms. Citrix owns the solution and responsibility and thus if Microsoft becomes distracted it is prepared to fill the gaps.

Yes, The Cloud Can Be A Security Win

There are so many different kinds of clouds — public, private, hybrid, internal — that many businesses and customers have difficulty deciding which is the right one for them. Furthermore, many businesses may use a few different variations of cloud environments — a private cloud for their own intranet, a hybrid cloud to keep some data on premises and some off premises to meet compliance regulations, and a public cloud for low-risk data.

These different types of environments make it difficult for IT and security teams to monitor every cloud on every device, or to monitor access requests for each different type of cloud environment. If you don’t control the cloud or where your data and apps reside, don’t manage them, or don’t know what you have in the cloud, your risk starts to sprawl and you don’t even know what’s happened when there’s a breach — or where to start to remediate. Follow these guidelines to make sure you avoid the cloud’s possible pitfalls.

Skype for Business from the Azure Cloud!

Times have changed! Today, calling from a cloud has a whole new meaning, with Skype for Business Online and Citrix XenApp and XenDesktop for Azure. Co-developed by Microsoft and Citrix, this unique solution brings not only telephony, but a full repertoire of Unified Communications features to the Azure cloud.

Introduction to Isolation Groups in XenDesktop

By design, App-V applications are isolated from each other and each AppV application is run within its own separate virtual environment—they do not share any data with other AppV applications. While this application isolation is welcome, as it promotes application compatibility by preventing any cross-application conflict, there is a need, at times, to overcome this restriction in certain strategic scenarios.

What Does Windows Server 2016 Day 1 Support Really Mean?

Citrix will support Windows Server 2016 on Day One! But what does that really mean? Does that mean that if I got my hands on the released bits of Windows Server 2016 on X Day of X Month (remember, I can’t tell you the actual release date) that I could then install XenApp and XenDesktop 7.11 on it and start using it? Immediately? Well, in a word, yes. Yes, it does. It’s really that simple. So, you see, there is no need to take the old approach to a new server OS and wait years to start working on it. You can truly start deploying and testing your own apps on Day 1 with XenApp and Windows Server 2016.

XenApp 7.11: Scalability & Economics on Microsoft Azure

Deploying Citrix XenApp 7.11 workloads from the Microsoft Azure cloud can give your IT organization a strategic advantage since it enables the delivery of desktops and applications in an agile way – you pay only for what you use. In fact, the price point for deploying a XenApp farm on Microsoft Azure can be as low as $6.89 per month per user.

nFactor authentication – MFA on steroids

The latest version of NetScaler has deeper integration with nFactor and can now be used with NetScaler Gateway and Unified Gateway. With nFactor you can configure an unlimited number of authentication factors. You are no longer limited to just two factors and you can get creative on how to chain them. Configuration will depend on the security policy and many times, user adoption and training are considerations to look at.

StoreFront Aggregation Groups Revisited

Over the past 12-18 months, we have seen a dramatic shift with the number of deployments using Web Interface versus StoreFront to the point that StoreFront is the de facto standard in new environment builds and migrations that we are seeing within Citrix Consulting. The majority of these deployments are also leveraging advanced multi-site settings in some way: either Optimal Gateway Routing to enable the use of HDX Insight for internal (non-Gateway users), user farm mapping to assign different groups of users to different farm sets, or aggregating resources from multiple farms/sites to collapse duplicate applications and/or desktops behind a single icon.

Getting Started with the Citrix HDX Pi – A step by step walkthrough

1463594298798

A few months back, I wrote a blog on how to configure the Raspberry Pi thin client to access Citrix workloads. If you are completely new to the HDX Pi and want to learn more about the benefits, this is a good place to start. Since then Citrix announced the HDX Pi and I have received requests from members of the community to blog on configuring the HDX Pi. So here it is!

What you need:

  • One or more HDX Pi’s ( Microcenter edition)
  • ThinLInx Managment Software

Configuration

The HDX Pi comes pre licensed for the ThinLinx Management Software (TMS). So you can go to the ThinLinx website and download TMS and install on a windows PC. Once installed, run TMS.

Connect the HDX Pi to the network in addition to the obvious (keyboard, mouse, display). Once the Pi boots up, you will see the client within TMS.

8-5-2016 4-24-44 PM

You can now update a number of parameters and push files to the device within TMS

  • Change the name
  • Change protocol to HDX if you prefer
  • Push SSL certs if needed (If you are using private certs on Storefront for instance)
  • Change network parameters (if you dont want to use DHCP for instance or use a custom DNS server)
  • Change display parameters.

8-5-2016 4-25-33 PM

 

 

8-5-2016 4-26-23 PM

TMS is also how you would push new firmware to the device.

Once you are done with the configuration changes, reboot the device. Once rebooted, you should see the updated parameters within TMS.

8-5-2016 4-26-43 PM

 

Once rebooted, you will have to specify the URL that you want the Pi to connect to. This is your Netscaler Gateway URL.

After you enter the URL, you will be prompted for credentials.

Once authenticated by the Netscaler, you get prompted to pick the Store after which you see your applications and desktops.

Some Caveats to keep in mind

One catch with TMS today is that the URL does not persist unless you save it at the Pi itself. To do this, while at the storefront screen, use the Ctrl+Alt+C key combination and hit “Save Settings”. Now reboot. The HDX Pi will now authenticate and take you right to your apps once rebooted.

The TMS server will only discover devices on the same subnet. So make sure that your TMS server and Pi are on the same subnet will configuring the devices or else discovery will fail.

Viewsonic version of the HDX Pi is also available. However the configuration procedure is a little different and will be covered in a future blog post.

Once the configuration URL is saved, as mentioned earlier the device will boot straight into storefront using credentials provided initially. In order to configure a new store, you can clear config and reset to default on the device or you can factory reset the device via TMS.

Keyboard Shortcuts:

  • ctrl alt r twice to factory reset
  • alt f4 to exit HDX screen
  • ctrl alt v – volume
  • ctrl alt c – config screen
  • ctrl alt t – terminal

To learn more about performance check my previous blog. I look forward to your feedback!

 

LUMA SURROUND WIFI SYSTEM – MY INITIAL THOUGHTS

20160725_150333

Back in February, I noticed Luma on Kickstarter. What made it compelling to me was the concept of a mesh network, which could in theory remove all deadspots around the house and guarantee excellent network throughput everywhere.

20160728_093516

 

 

 

As most engineers out there, I have a large number of wireless devices throughout the house and consistent throughput has always been a concern. In addition Luma promised some interesting security features including the ability to link users to devices on the network and then apply parental controls on a per user basis. The product also promised to proactively monitor the security posture of connected devices (done through a cloud based service). So for these reasons I pre ordered a 3 pack and received my devices earlier this week. I finally hooked up the devices and wanted to share my initial thoughts.

20160725_151749

SETUP

Setting up the Luma is a breeze! You literally hook up one of the devices to your modem or router, download an app via Google Play or the Apple Store and it walks you through the entire setup step by step.  I have my Linkys 1900ac and Luma running in parallel, both hooked up to my modem. I use the Luma primarily for media streaming devices. One of the access points did not successfully configure the first time during setup and i had to go through the process again. The process was extremely simple and intuitive nonetheless. Luma is geared to those who have zero knowledge about networking. Even my mom would be able to get through the configuration process successfully.

The tool recommends ideal locations to place the access points but following the recommendations, I noticed that the throughput was not optimal. I eventually ended up placing the access points as close to each other as possible on the three floors and that seemed to give the best throughput.

Screenshot_20160728-093204

THE GOOD

  • As discussed above, the setup is extremely intuitive and simple
  • The product will appeal to most consumers who are not tech savvy due to the simplicity of the setup and exceptional network coverage.
  • Linking devices to users and applying parental controls on a per user basis is an awesome feature that appeals to parents like myself.
  • You can completely eliminate deadspots throughout your house while maintaining consistent throughout everywhere
  • Network security scans that monitor the security posture of all your connected devices is a nice feature. However it is cloud based.
  • The iOS and Android apps are very well designed, although they are pretty limited in features as of now.

THE NOT SO GOOD

  • Zero configuration options from a network perspective besides setting up a WiFi network. Not even the most basic settings.
    • No DHCP configuration options (scope, reservations, lease time etc)
    • No port forwarding
    • No advanced firewall options
    • No QoS settings
  • Cannot configure multiple Wireless Networks (beyond the guest network). Cannot separate 2.5 and 5 Ghz networks
  • Requires you to setup a cloud based account and uses cloud based network scanning solution that cannot be turned off. This is a major concern for some.
  • From what I can tell, the Luma acts as a forward proxy and also handles DNS resolution which is NOT CONFIGURABLE. I can see why this is necesary to filter traffic and apply parental controls. However I noticed a significant delay in DNS resolution (up to a 5 second delays) when trying to resolve URLs. This is extremely unappealing and a major show stopper for me. I also assume that this data is also flowing through their cloud service which is concerning.
  • While handling streaming video, so far I am noticing periodic network drops and freezing which I never noticed with my Linksys 1900ac. I will need to investigate further.
  • The throughput offered by the first wired Luma that you setup is almost three times higher than the rest. I am getting 300 Mbps on the main Luma and only about a 100 on the other two Lumas. I had read some reviews that claim the same flaw. With that said, 100 Mbps is not bad 🙂
  • A bunch of features that were promised on Kickstarter have not made it into the initial release. However, the support team tells me that they are extremely aggressive about updates and are updating the mobile app twice a month and releasing firmware updates pretty aggressively. So I’m pretty certain that they’ll catch up.

THOUGHTS OVERALL

In addition to Luma, there are a few other products out there that offer a similar solution, Eero being the most popular. The real differentiator with Luma (at least in theory) were the advanced parental controls and the fact that the devices itself are much more beefy with quad core processors and such. While I am honestly a little disappointed with my initial experience, especially with regards to all the missing advanced network features, I am cautiously optimistic that these will be rolled into the product soon. So here are my initial thoughts:

  • If you are not tech savvy and want a really simple solution that just works, provides you consistent coverage everywhere and you dont care about advanced network features, then LUMA IS FOR YOU!
  • If cloud hosted services are a concern, then Luma is not for you.
  • If you already own a Linksys 1900ac or a similar advanced router, I would honestly hold back for now and wait to see how the product evolves. Too many gaps as of now.
  • If your main reason for looking at the solution was parental controls, it might be a fit however not all the features have been rolled out. You could look at Circle from Disney to complement your existing wireless solution. You could also take a closer look at Eero.

I will update this post as I have more information to share!
