Zoom A/V Offloading for Citrix Virtual Desktops Part 1

Introduction
Zoom developed a VDI optimisation solution that enables and allows for Audio and Video (A/V) processing similar to that of Microsoft Teams today and Skype for Business originally deploying and leveraging a client and backend service software components. Zoom refers to the backend as a “Zoom Client for VDI” and then the endpoint runs the “Zoom Media Plugin” processes and handles the A/V data traffic.

Zoom Pre-requisites & System Requirements
1.Prepare your UAT provisioned Citrix Virtual Desktop image to install the “Zoom Client for VDI” downloadable at – https://zoom.us/download/vdi/ZoomInstallerVDI.msi which is also referred to as the “Zoom Installer VDI” and or “Host Installer”.
2. Prepare an endpoint running a supported OS to run the “Zoom Media Plugin” Windows, iGel, eLux, HP ThinPro OS and Ubuntu. In this example we’ll focus on installing the “Citrix HDX Media Plugin” for Zoom which you can download at – https://zoom.us/download/vdi/ZoomCitrixHDXMediaPlugin.msi. The full list of available Zoom Media Plugins for Citrix is available at – https://support.zoom.us/hc/en-us/articles/360031096531-Getting-Started-with-VDI#h_44458af3-695a-44f0-9cbc-b753f00b3c00.
3. Initiate a test Zoom video conference call and observe HDX offloading of A/V from the Citrix Virtual Desktop to the endpoint running the “Zoom Media Plugin“, which is passing the A/V data traffic to the Zoom Cloud MMR platform reference the Zoom VDI Optimisation node at – https://support.zoom.us/hc/en-us/articles/360031441671#h_70badc99-f2fd-417e-bd46-59493ab7047b.
4. I didn’t have to configure anything within the Zoom Cloud MMR, neither my personal Zoom account it all worked out of the box.

Citrix Pre-requisites & System Requirements
You’ll need a CVAD UAT environment to deploy fresh VM to install the “”Zoom Client for VDI” and a test Windows endpoint to install the “Zoom Media Plugin” onto. In my initial testing I am running a freshly installed Citrix Virtual Apps & Desktops (CVAD) 1912 Long Term Service Release (LTSR) which is run in my own personal “cloud” home lab in AWS EC2 geographically located in N.Virgina, USA. Zoom is also listed within the Citrix Ready website at – https://citrixready.citrix.com/category-results.html?search=Zoom.

Deployment Overview
The installation and configuration for Zoom Optimisation Meetings for VDI is incredible frictionless that it took me less than 5 minutes to complete the deployment, then test my first ever Zoom video conference call running in a Citrix Virtual Desktop. The following in order of events.

1.Download “ZoomInstallerVDI.msi” and install the “Zoom Client for VDI” within my PoV Citrix Virtual Desktop.
2.Download “ZoomCitrixHDXMediaPlugin.msi” and install the “Zoom Media Plugin” onto my Windows endpoint where I connect to my Citrix Virtual Desktop through Citrix Workspace app for Windows CR.
3. Downloaded the Zoom app from the Apple App store – https://apps.apple.com/gb/app/zoom-cloud-meetings/id546505307, please this link if for the UK Apple app store. I completed the first user experience and register myself a Zoom account.
4. I started Zoom instant meeting and then invited another participants using a meeting ID# and by default each room as a unique password to join, for more on the security of Zoom see towards the end.
5. I successfully logged into my Citrix Virtual Desktop and run “Task Manager” likewise I started “Task Manger” on my local Windows endpoint.
6. I clicked to start “Zoom VDI” app within my Citrix Virtual Desktop which there prompts you to enter in “Meeting ID” (preferred as it’s always a unique #) or “Personal Link Name”, select your preferences for audio and video upon joining. Next by default I expected to join the virtual meeting but was halted as I was required to enter in a passcode/password to actually “join” Zoom video conference call currently in progress.
6. Zoom video conference call started and immediately VDI optimised with the A/V traffic been processed locally on my local Windows endpoint.

Important Note: I only tested VDI Optimisation from within my AWS EC2 personal lab boundary as I don’t have a physical Windows endpoint at home to test it with so that will be included in part 2, my goal was to see how easy it was and if it worked a frictionless as I thought it might just by reading through Zooms online documentation.

Demonstration of Zoom A/V Offloading
In the initial demo below for part 1, I connected to a Citrix virtual desktop running in AWS EC2 (N.Virginia) in a double hop scenario, as Zoom don’t currently support Apple Mac endpoints for any Zoom VDI offloading. The video of me you see in the demo video is from my personal iPhone (London, England) connected to the Citrix virtual desktop (N.Virginia, USA). Note I didn’t test bi-directional video and or audio communication, and a few other topics, which I will follow-up in the future time permitting, but as you can see the Zoom video conference call offloads the Zoom A/V traffic to the connected Windows endpoint effortlessly! Great work Zoom I am well impressed with my initial testing today.

Employee Experience VDI Limitations
Zoom and provided a high level feature “comparison” matrix – https://support.zoom.us/hc/en-us/articles/360031441671-VDI-client-features-comparison#h_fceae51c-f385-4a20-bd54-c7c50f186c15 depicting the differences between the Zoom VDI client vs. the Desktop and Web clients. Its important to be mindful of these differences in order to properly educate your employees when dealing with service desk requests or better prior to rollout by posting an internal article on your companies intra or extranet. The following for me are important limitations to be aware of, when deploying and consuming Zoom through a Citrix Workspace lens.

– Maximum resolution of 1080p and up to 380p for thin client h/w.
– No dual monitor support
– Support for up to 9 visible video participants
– No Apple Mac device support for HDX offloading of Zoom A/V data traffic

Security & Privacy
Zoom has recently been in the press surrounding security and privacy practises “Google it”, with that been said its worth noting that Zoom as an organisation committed to a 90 day security plan centred on its platform + client security, today 22/04/2020 they published the following article on there corporate blog “Zoom Hits Milestone on 90-Day Security Plan, Releases Zoom 5.0” – https://blog.zoom.us/wordpress/2020/04/22/zoom-hits-milestone-on-90-day-security-plan-releases-zoom-5-0/, so be sure to read through it.

Final Thoughts
I have alot more questions and tests to do the above is only the very beginning, next I’ll be evaluating fallback scenarios, more of a focus employee experience use-cases including unconsidered needs, tweaks of course and finally testing a ๐Ÿ™‚ endpoints in London, England whilst my Citrix Virtual Desktop in N.Virgina, USA as this is how I have tested these types of Unified Communications (UC) or Video Conference platforms all the way back to Lync with the Citrix HDX Optimisation pack.

I honestly found the setup and deployment of Zoom’s VDI Optimisation ridiculously simple its incredibly frictionless! I guess thats why many folks are still continuing to consume and use Zoom for video conferencing.

Journey to The Nirvana Phone within the Workplace Part 1

Does it even actually exist? Truthfully it depends on how we as humans (employees) choose to consume the apps, data and network services on them for the purposes of personal and workplace usage.

In preparing to write this article I googled “The Nirvana Phone” the top search result is a Wikipedia entry – https://en.wikipedia.org/wiki/Nirvana_Phone (huge smile) along with 3 YouTube videos and very very very familiar face followed by yet another huge smile + found memory flashback because its Citrix CTO of Emerging Technologies Chris Fleck demonstrating using an iPhone 4 running a Windows 7 VDI (DaaS) delivered by Citrix Receiver on iOS connected to a monitor with a Apple VGA adaptor and portable paired Bluetooth keyboard. This is actually a key subconscious moment for me that has had a profound affect on me, and how I approach and look at the world around me today. So when I first saw that video I immediately hunted among work colleagues and friends for that Apple VGA cable adaptor to test it out for myself with my iPhone 4 and oh boy I was NOT disappointed yes it still had a way to go but as a real world working prototype concept enabling anyone in the world who uses Citrix and is the owner of an Apple iPhone 4 to use it in such a way is mind blowing even now while also demonstrating the WOW effect that this gaming changing technology will have on the workplace, even today nearly a decade on I am using one of many Nirvana Phones out there in the market running Citrix Workspace app available from all major app stores to actively take full advantage of my iPhone XR “Nirvana Phone” as it was intended in Chris Flecks original video below to be flexible and adaptable between sandbox vs. native mobile apps, browser based SaaS web apps and of course Citrix virtual apps* & desktops** formerly known as XenApp* and XenDesktop**.

I mentioned earlier it was a “key subconscious moment” for me personally as it validated and meant to me that I can use a devices as such as the Apple iPad or iPhone as a work device this is super cool and practically appealing to me, even today at Citrix they are evolving this a reality of the “Nirvana Phone” with the Intelligent Experience – https://www.citrix.com/lp/intelligent-workspace.html by distilling the friction + complexity of apps into simple to consume actions and insights from Citrix Workspace app vs. web portal.

Lets go back in time to late 2012, I’ve joined Citrix and at Christmas I’m gifted with an Apple iPad Mini which I used a lot running and working from @WorkMail, @WorkWeb (inclusive of my iPhone) and occasionally I consume my Windows 7 VDI on my iPad Mini because I can’t find a Bluetooth enabled mouse that works with it but it does work great for tasks such as lengthily emails using the soft/digital keyboard while travelling to and from events around the world like Citrix Summit and ServTech likewise locally on trains tethered to my iPhone as train Wi-Fi does not really exist in the 2012.

Fast world to 2015 and Citrix releases a prototype Bluetooth enabled mouse called the “Citrix X1 Mouse” and who is back demoing this capability? Yes Chris Fleck is back again continuing to edge closer to the “The Nirvana Phone” workplace operating model. What most folks are not aware of I could not make Citrix Summit that year due to a family member whom was medical very unwell, yet one of the best humans I have ever had the privilege of working with in my professional working career is Caz and she brought me back an original X1 Mouse prototype because she knew its importance and value to me with my digital first nature with modern touch enabled devices like iPhone’s and iPad’s beyond today’s modern day typewriters which to be honest looking back I was held back by the technology interfaces of my time VGA to HDMI and finally entering into the main stream market late 2018 and into 2019 casting capabilities matching what we use at home Google Casting for example now coming into the Workplace like Click Share but for me they are still both a v1 they need to mature over time.

Fast forward later in May of 2015 and the final piece for me falls into place with the Citrix Workspace Hub prototype demonstrated again by Chris Fleck with the at current CEO Mark B Templeton.

Fast forward again now its 2018 and the Citrix Workspace Hub officially launches and is available through select thin client vendors that choose to be in the program. I get a Citrix WorkspaceHub device for my own personal usage from Citrix ServTech and the first thing I do when I get home is plug it in and start using it, you can see me demoing it the first time I used it at home in 2018 from my annual series of “How I worked in 20XN” obviously 2018 edition which is embedded below, fast forward to 2 minutes, 30 seconds to watch it.

Today its 2019 the current year of this post and well lets say I have totally shifted to using “The Nirvana Phone within the Workplace” because I choose to but more important the technology of my current time allows me to, and I’ve ditched the modern day typewriters up to 12-17% of my total workplace through-out 2019. You still need a larger screen and laptop for creator personna’s but for the consumer personna’s personally I don’t believe you do at a high level. You can read my journey over 2019 transferring to the “The Nirvana Phone” operating model in the workplace, starting with the original post in the series of “The Future of Work is Today NOT Tomorrow” – https://www.mycugc.org/blogs/lyndon-jon-martin/2019/03/17/the-future-of-work-is-today-not-tomorrow-part-1, followed by part 2 –https://www.mycugc.org/blogs/lyndon-jon-martin/2019/03/28/future-of-work-is-today-not-tomorrow-part-2 and part 3 – <coming>.

In closing part 2 series will focus on how to get started and work they way I do every working day at Citrix where ever I am.

How vs. where I worked from in 2018

I’m often asked why Citrix? The answer can be a simple vs. complex one, therefore I choose to demonstrate why Citrix through proactive evangelism by recording myself using my Citrix Workspace actively through-out the year, which initially began in 2016 and lead to the original How vs. where I worked from in 2017 video available at – https://twitter.com/lyndonjonmartin/status/949316537021812736.

Introduction to “Session Watermark”
The latest release of the XenApp & XenDesktop Service powered by Citrix Cloud or if you are performing a private cloud (on-premises) upgrade or net new installation of XenApp & XenDesktop 7.17 has some NEW features (another post brewing) and one that I have been waiting on for quiet sometime now has not finally arrived (WAHOO!) and its VERY VERY simple to configure and aids in improving your security posture (I believe) for delivery of apps & desktops powered by Citrix against e.g IP theft. In the below tweet can you see it?

The above is from my initial tests using a Windows Server 2016 VM hosted in Azure Northern Europe region running the 7.17 VDA configured to my Citrite #CitrixCloud XenApp & XenDesktop Service so I did not need to upgrade anything to get this new SHINY cool feature yes I said it SHINY. All I was required to do was deploy a new Windows Server 2016 VM from the Azure marketplace, domain join it, install the VDA and connect it to my Cloud Connector and I was ready in less than 25 minutes from initially deploying the VM from the marketplace.

Finally on a personal note for me Citrix SysAdmins enabling the “Session Watermark” feature obviously initally tested in a safe environment e.g UAT with a few users from a couple of departments and then rolling it out into production (as when/how your ready) will be making IT the modern “App & Desktop Security Heroes“. IT can apply and configure these new policies to be the most right vs. relevant for your organisations security needs while not hindering the end-users Rich HD eXperience.

Session Watermark Policies
You have 8 watermarking policies to apply with the 9th one enabling this security capability or feature set with the following list of quirks, suggested policy configuration and more available at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/current-release/policies/reference/ica-policy-settings/session-watermark-policy-setting.html.

Before we get started it is worth mentioning that this feature does add an overhead to the compute on the backend (VDA side) and therefore it is suggested to enable up to two water marking features or items. In my overview of this feature I will wont cover off the cost of implementing this security policy as there are multiple variables to consider e.g HDX Graphics Mode and associated policies to provide the right vs. relevant end-user experience vs. how many watermark items do I apply? I have begun testing so bare with me and I’ll publish my findings either on my personal blog here or on https://www.mycugc.org under the “Expert Insights” area.

Enable session watermark
By default this feature is DISABLED as the default behaviour which I believe is the right approach considering its Citrix’s initial release of this #security feature (in my personal view) and secondly online documentation at eDocs suggested recommendations it to enable NOT more than two watermark text items. Finally * indicates that this policy is DISABLED by default when Session Watermark is enabled.

Include client IP address
* This is the IP addr of the device connecting to the virtual app & desktop.

Include connection time
* Utilises the following format yyyy/mm/dd hh:mm to display the users initial connection time to there virtual app or desktop.

Include logon user name
ENABLED by default when you enable Session Watermark as a policy and uses the following format USERNAME@DOMAINNAME is most optimise for 20 characters or less otherwise truncation might occur of the users logon username.

Include VDA host name
ENABLED by default when you enable Session Watermark as a policy and provides the VDA hostname e.g ne1vad01

Include VDA IP address
* Provides the internal IP addr that corresponding the VDA’s hostname e.g ne1vad01 = 10.1.0.7

Session watermark style
ENABLED by default using “Multiple e.g displays five watermark labels” when you enable Session Watermark as a policy or you can configure “Single e.g displays a single watermark label in the centre of the session“. TIP switching to SINGLE and sticking to two watermark text items for me in my initial tests is a good starting policy however time will tell as I continue to test out this new feature and its capabilities with different HDX Graphics Modes and associated tweaks.

Watermark custom text
* A unicode maximum of 25 characters is supported if you exceed this limit it will be truncated.

Watermark transparency
ENABLED by default set to “17 out of 100” when you enable Session Watermark as a policy, personally I think setting it to just 1 is fine in my initial tests as you want it to be not so in your face to the end-users to be bluntly honest.

Understanding What’s New with the latest XenApp & XenDesktop 7.15 LTSR

The following content is a brief and unofficial prerequisites guide to setup, configure and test accessing secure by design virtual apps and desktops powered by XenApp & XenDesktop 7.15 prior to deploying a PoC, Pilot or Production environment by the author of this entry.

What is the difference between LTSR vs. CR for XenApp & XenDesktop 7.x?
The Long Term Service Release (LTSR) program for XenApp and XenDesktop provides stability and long-term support for XenApp/XenDesktop releases while the Current Release (CR) provides customers with the very latest version of XenApp and XenDesktop which includes the latest innovations e.g EDT v2

XenApp & XenDesktop 7.15 LTSR Feature Summary Comparison with 7.6 LTSR
The following is a simple one PDF page document that lists all the feature capabilities from initial first LTSR which was XenApp & XenDesktop 7.6 Feature Pack (FP) 1-3 through to the current LTSR XAD 7.15 including the CR releases in-between so its absolutely worth booking marking in your browser or better yet download it to keep it to hand for customer conversations – https://www.citrix.com/content/dam/citrix/en_us/documents/data-sheet/xenapp-xendesktop-715-ltsr-feature-summary-comparison-to-76-ltsr.pdf.

Noteworthy Points What’s New vs. Excluded
I’d very strongly recommend that your read the following CTX article – https://support.citrix.com/article/CTX205549 entitled “CTX205549 FAQ: XenApp, XenDesktop, and XenServer Servicing Options (LTSR)” and to ensure that you remain compliant post your update/migration to 7.15 LSTR you should download the “CTX209577 Citrix LTSR Assistanthttps://support.citrix.com/article/CTX209577

Its also worth noting the following that are classed as “Excluded Features/Components/OSes” from the XAD 7.15 LTSR but I’d like to stress PLEASE PLEASE refer for eDocs for full caveats vs. supporting statements at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/whats-new/7-15-ltsr-initial-release-.html+ and these listed notes are based upon the initial release however there is now a Cumulative Update 1 (CU1) already available so be sure to read through it as well at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/whats-new/cumulative-update-1.html.

OSes+
– Windows 2008 32-bit (for Universal Print Server)

Behavioural Changes
– Upgrading a XA 6.5 worker to a new 7.15 VDA is now slightly different and the detailed process is listed at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/upgrade-migrate/upgrade/upgrade-xenapp-6-5-to-vda.html and also be sure to review the XenApp 6.x Migration Tool at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/upgrade-migrate/xenapp-worker-upgrade.html and you review the migration tool by watching the embedded YouTube video below.

Finally while your planning your migration to XA 7.15 (FMA) from 6.5 (IMA) you will mostly likely be upgrading vs. migrating away from WIF so please be sure to read and how to migrate features to StoreFront from your WIF environment at – https://docs.citrix.com/en-us/storefront/3-12/migrate-wi-to-storefront.html. Equally I’d encourage any organisation reading this to review how-to setup and configure the “unified user experience” for Citrix Receiver vs. the Green Bubbles which will provide a much better experience for users you can enable it by quiet easily once you’ve read through the following article in eDocs at – https://docs.citrix.com/en-us/storefront/3-12/manage-citrix-receiver-for-web-site/unified-receiver-experience.html.
– Follow the supported leading best practises for upgrading the 7.15 LTSR by reviewing the following node within Citrix’s eDocs – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/upgrade-migrate/upgrade.html
– VDA installation failures for Win 10 N Editions that don’t include Microsoft Media Foundation can now be acknowledged via the installation GUI of the VDA vs. automated deployed (unattended) there is a new option “/no_mediafoundation_ack“.

Excluded Features & Compoments+
– HDX Graphics Mode – Framehawk
– StoreFront Citrix Online Integration
– AppDisks
– Personal vDisk is excl for Win 7, 10
– Load balancing of Session Recording which was an experimental feature in 7.14

What’s Deprecated in the 7.15 LSTR
A full list of what is deprecated is available at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/whats-new/removed-features.html and I am only going to list a few points that I believe of most interest to those whom read my blogs or if your just a Citrix SysAdmin vs. Consultant reading this blog post.

What’s New
– Machine Catalog’s functional level within your Site from 7.9 do not require an upgrade
– Machine Creation Services (MSC) now supports generation 2 VMs with Microsoft System Center Virtual Machine Manager SCVMM
– The FMA or 7.x version of Local Host Cache (LHC) is now enabled by default BUT note that if it was disabled from a prior release of the XAD 7.x then you need to enable it and disable Connection Leasing (CL) https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-9/manage-deployment/connection-leasing.html which was initially introduced into the 7.x platform to provide a fallback if your SQL database connection was lost or unavailable until LHC was re-introduced in XAD 7.12 – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-12/manage-deployment/local-host-cache.html but was not enabled by default in the 7.12 release CL was primarily utilised.
– Director App Failure Monitoring – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/policies/reference/virtual-delivery-agent-policy-settings/monitoring-policy-settings.html#App_Failure_Policy_Settings

Security Leading Best Practises
– General Overview https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/best-practices.html.
– Securing your StoreFront 3.12 environment – https://docs.citrix.com/en-us/storefront/3-12/secure.html
– Standardise on a single organisation user identity platform e.g AAD by leveraging NetScaler + + StoreFront + FAS which can convert SAML vs. OAuth tokens into virtual smartcards per configured Store within StoreFront to then SSO a user onto there intended virtual apps & desktops without requiring to re-enter his/her in a directory username + password for that resource location (What’s this? Read – https://docs.citrix.com/en-us/citrix-cloud/citrix-cloud-resource-locations.html).
– Slightly obvious to an Citrix expert vs. Citrix Partner but its worth highlighting for newbies to Citrix virtualisation technologies is that XAD management provides Delegated Administration to manage just enough access for different members of the IT vs. compliance departments/business units to have just enough access to complete there daily vs. weekly vs. monthly activities vs. tasks – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/delegated-administration.html and for remote secure access to virtual apps & desktops you will need implement NetScaler Unified Gateway – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/storefront-netscaler.html which can also enable and allow your organisation to control authentication at the edge of your network e.g 2FA vs. MFA vs. using Biometrics with supported 3rd Citrix Ready solutions so check out – https://citrixready.citrix.com. Finally you can also engage with SmartAccess capabilties when fronting XAD for R/A with NUG so check out the following resources for NS 11.x.n – https://docs.citrix.com/en-us/netscaler-gateway/11/integrate-web-interface-apps/ng-smartaccess-wrapper-con/ng-smartaccess-xd-config-con.html and NS 12.x.n – https://docs.citrix.com/en-us/netscaler-gateway/12/integrate-web-interface-apps/ng-smartaccess-wrapper-con/ng-smartaccess-xd-config-con.html and there is also a CTX article entitled “CTX227055 Smart Access Guide for NetScaler Gateway, StoreFront and XenDesktop” to review at – https://support.citrix.com/article/CTX227055 and finally you can configure Pre-Authentication scans to check that the connecting end-point is compliant (Refer to VDI Handbook section below).
Enabling TLS or Transport Layer Security for ICA/HDX Session – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/secure/tls.html for a detailed how-to from the first LTSR check out the following blog article at – https://www.citrix.com/blogs/2014/12/11/how-to-secure-ica-connections-in-xenapp-and-xendesktop-7-6-using-ssl/ or download the white paper entitled “Citrix XenApp and XenDesktop 7.6 LTSR FIPS 140-2 Sample Deployments” from – https://www.citrix.com/content/dam/citrix/en_us/documents/about/citrix-xenapp-and-xendesktop-76-fips-140-2-sample-deployments.pdf. During some research I also came across the following CTX article to disable TLS 1.0 for XAD 7.6 LTSR which may or may not be useful to you check out – https://support.citrix.com/article/CTX215447.
– How do I assign the right vs. relevant security or UX policy? Refer to the built-in policy templates which you can read at – https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/policies/policies-templates.html which include the same policy type for modern vs. legacy OSes.

Citrix VDI Handbook for the 7.15 LTSR
Recommended pages of interest to read from “Citrix VDI Best Practices for XenApp and XenDesktop 7.15 LTSR” – https://docs.citrix.com/content/dam/docs/en-us/xenapp-xendesktop/7-15-ltsr/downloads/Citrix%20VDI%20Handbook%207.15%20LTSR.pdf which I am commonly asked about so I thought it makes sense with the current LTSR to list them out here for everyone to focus on what is right vs. relevant for PoC’s e.t.c

– Page 11 which focus on CCS Methodology
– Page 32 Five-Layer Design Model and Conceptual Architectures for XAD environments
– Page 35-37 Site topology covering latency, bandwidth vs. number of users
– Page 50-52 covers StoreFront keywords to the behaviour of the delivery of virtual resoucres
– Page 52 Scaling vs. sizing of your StoreFront cluster
– Page 54 Calculate what NetScaler required SSL through-put however i’d strong recommended engage with your Citrix rep for leading best practise vs. guidance as this can/may differ dependant upon your choose appliance vs. firmware version.
– Page 58 Implement GSLB with HDX Optimised routing to ensure connecting users in a regional vs. global deployment connect to better NUG by proximity.
– Page 63 HDX Display Protocol
– Page 66- User Profile types for Local, Roaming, Mandatory & Hybrid vs. virtual apps & desktop chooses model
– Page 79 Built-in Policy templates to optimise the UX based upon your organisational requirements
– Page 88-93 vCPU/RAM/Storage I/O vs. User workload types light, medium and heavy
– Page 94-97 SQL database sizing vs. scaling 5K up to 15K including expected database growth
– Page 98-99 PVS SQL database guidance for suggested sizing
– Page 104 XAD Controller sizing vs. scaling per 5K users which also includes a calculation
– Page 105 LHC considerations if enabled to re-size your control infrastructure for XAD
– Page 107 Citrix Cloud connector sizing for 5K users in private vs. public cloud
– Page 113-116 SQL Database sizing
– Page 121-129 PVS Accelerator with XenServer
– Page 132-140 Hardware Formulas for sizing vs. scaling including GPU(s)

Deploying a XAD 7.15 LSTR PoC
Coming…

What Citrix Receiver & HDX Optimisation Pack should I deploy?
You should consider reviewing and if fit for purpose for your organisation implement the Windows 4.9 LTSR Citrix Receiver version – https://docs.citrix.com/en-us/receiver/windows/4-9.html along with if you utilise Skype for Business for UC the LTSR of the HDX Optimisations Pack – https://docs.citrix.com/en-us/hdx-optimization/2-4-ltsr.html and you can find out more information about the lifecycle at – https://support.citrix.com/article/CTX200466.
