XenServer for XenApp - Better Together

Overview

For the last few years, IT professionals have questioned whether it makes sense to virtualize XenApp environments. The answer has always been “it depends.” In short, that answer has not changed. Most organizations realize that having an environment that is 100% physical or 100% virtual may not be the best solution. Adding server virtualization impacts single server scalability, requires management and technical expertise, and adds environmental complexity. However, the benefits can include higher utilization, greater availability and increased flexibility. Before deciding the best solution for your environment, the challenges must be considered, the goals must be understood and the environment must be conducive for server virtualization.

Objectives

IT organizations everywhere are either currently evaluating or in the early phases of investigating server virtualization solutions. While there are many compelling arguments for the adoption of virtualization technologies, the main drivers from both a business and a technical perspective can be categorized into three distinct groups:

∙Higher utilization

∙Greater availability

∙Increased flexibility

Higher Utilization

Organizations have built XenApp server farms to deliver varied types of applications, ranging from mission-critical line- of-business applications to the outdated, resource-intensive applications that are only occasionally used. Depending on the application and server resources, a single XenApp server has the potential to deliver applications to a handful of users or several hundred users simultaneously. Increased scalability can have a large impact on reducing the overall environment‟s server footprint if overall resource utilization can be increased. Trying to get more efficiency from of a XenApp environment without requiring huge investments in hardware is a challenge organizations face. This challenge focuses on the following questions:

∙How to best fully utilize servers without sacrificing the user experience?

∙How to allow systems to perform multiple functions without requiring significant integration testing?
