Citrix Virtual Desktops – Options And Costs
Citrix XenDesktop and Citrix XenApp now offer customers two different computing models for centralizing their client computing. I have had about a dozen or so customer conversations regarding where the best use of each technology is. I want to share that with everyone.
People ask me whether the IT and business problems to centralize have changed. The answer is – they have not. Costs, compliance/security and flexibility for access remain to be IT challenges that centralization can solve. If you think about the culprit that keeps the TCO of desktops high, it is application deployment and management.
The two problems that customers have been able to successfully address with XenApp are:
1. Delivering appa to users anywhere – typically customers start with virtualizing problem apps and grow their XenApp usage overtime.
2. Virtualizing the full desktop with all the apps – it has worked great for task based workers who use standardized locked down environments with few apps.
Overtime, XenApp has addressed several key challenges in addressing those requirements including scalability (via 64-bit), app compatibility (via app isolation environments any app can be made compatible with XenApp), graphics (via SpeedScreen), performance monitoring (via EdgeSight) and offline support (via portable app virtualization/streaming). This has enabled an even broader use of XenApp for virtualizing more apps within existing XenApp customer base.
