You don’t need XenDesktop for a virtual desktop

XenDesktop 7For years Citrix has a product to host applications from a centralized locations offering great flexibility and efficiency, called Citrix XenApp. In 2008 Citrix released XenDesktop, the VDI solution from Citrix. With this first release of XenDesktop it was possible to (only) publish a desktop hosted on a single user operating system (like Windows XP, Vista or 7).

Citrix has tried to choose an appropriate name for their products to help customers understand what product offers what solution (and reducing the ridiculous times they rename their products). Although this is an admirable attempt they failed to reach that goal.

A lot of customer assume that with XenApp they can (only) publish applications and with XenDesktop (only) desktops, how wrong can they be?

Gartner analyses the maturity of more than 1,800 technologies trends. Based on the maturity of a technology or trend a decision can be made to adopt or ignore, postpone or adopt the innovation.

In 2010 Gartner published the ‘2010 Special Report’ and consisted of 75 individual Hype Cycle reports, each of which gives a snapshot perspective of a key area of IT or business.

The IT industry acts on trending topics by creating products or solutions and convincing customer to adopt a certain trend or technology. Current trending topics are ‘Bring Your Own’, ‘Consumerization of IT’, ‘Cloud Computing’ and ‘Hosted Virtual Desktop’.

A trending topic (for many years) in The Netherlands is ‘Het nieuwe werken’ (The new working). A trend where flexibility, working from any location and using social media is accepted

Silverlight Logo

A customer has a (virtualized) Citrix XenApp farm scaled for 1500 concurrent users. The environment is based on Windows Server 2003 Standard with Citrix XenApp 5 (migration to XenApp 6.x is scheduled).

A business critital web-application is re-developped and requires Microsoft Silverlight. Before implementing Silverlight the impact should be determined. A big concern is a decrease in the capacity of the farm, number of concurrent users the farm can handle.

To determine the impact of Silverlight I’ve done some tests, including a LoadTest.
