Many IT departments view new or recently migrated XenApp/XenDesktop implementations as complete when users start accessing the production environment successfully. However, the use of a monitoring tool is often overlooked. The Virtualization Practice has published a new checklist-style white paper entitled Monitoring for Your Citrix® Infrastructure: Considerations and Checklist to help you determine how to best address this. The document provides the reader with numerous thought-provoking questions and line-item checklists without a single mention of a third-party vendor. By considering all aspects of monitoring, you are equipped to draw the best decision for your particular environment.

Late Tuesday, November 17, Citrix provided a public operational review update. The short summary is that the GoTo products will be spun off into an independent business, Citrix is focusing on its core competencies, and 1,000 people have been laid off. Having talked to a few people at Citrix, I know that these are challenging times.
In the virtualization marketplace, when a vendor expands its core business and attempts to grab a piece of the new market from an existing incumbent, the vendors view each other as competitors. In 2007, when Citrix purchased XenSource, VMware vSphere clearly became the enemy, and Citrix envisioned that XenServer + XenApp/XenDesktop would take over the virtual world. That didn’t quite happen.
How good an idea is it to virtualize XenApp? Way back in 2010, when more of the poles were ice, we asked is virtualizing Citrix XenApp a waste of time and effort? There were a number of benefits identified: hardware abstraction allowing easier image management and OS upgrades; options for higher availability and faster recovery, even failover; virtualization-enabled silo consolidation; and importantly, better management of user capacity on servers.
Yet, with XenApp running on Windows 2008 R2 memory limitations are of far less issue. Introducing a hypervisor has an overhead which can impact user density and can change Microsoft server license costs per physical server. Do these considerations outweigh other benefits? Hypervisor technology and performance has moved on considerably – what is the impact of that? What other services can virtualized XenApp drive?
Bromium have released vSentry 1.1 which will brings Bromium’s benefits of micro-virtualization and hardware based security to a far wider range of enterprise desktops. This is the release you’ve been waiting for: and if you’ve not been waiting, this is definitely the release to consider.
We’ve spoken before about Bromium when they unveiled their micro-virtualization trustworthy security vision. Bromium’s message and focus was simple “standard workspace security is reactive, not proactive“. Whatever you have in terms of anti-virus or malware detection is only good once a new threat is found, understood, a patch created and deployed. This poses the very important question “what is the impact of the time delay between threat found and threat contained?”. Bromium’s goal was to dramatically reduce that “and”.
You may contest, “ah, but I can solve this workspace threat issue by making physical desktops, virtual desktops”. This is not the case. We evidenced this in Virtual desktops (VDI) are different, but not hugely better in terms of security, than physical desktops. You do not deliver better security by simply virtualizing the desktop.
So what does vSentry v1.1 bring? How is it better than v1? What can this mean for your organisation?
Is Windows 2012 Remote Desktop Session Host (RDSH) better than Citrix XenApp? Citrix XenApp 6.5 is a market-leading product. Citrix XenApp may well be the first product businesses consider when deploying applications or desktops from a centralised service. Windows 2012 is very new. Windows 2012 RDSH, as a new service, doesn’t have the same number of partners or administrators with detailed experience.
Still, it’s a very good question.
It’s a very good question because Microsoft has worked hard to ensure that RDSH is a solution viable not only for large enterprises, but small and medium scale businesses and not-for-profit organizations, as well. Windows 2012 RDSH builds on a mature technology, a technology that is the most-deployed centralized desktop virtualization solution.
Yet, are you going to end up reading this article and get to an “it depends” answer? Let’s see.
