Optimizing Citrix?? XenDesktop?? for High Performance

By: Craig Thomas Ellrod

Overview of this book

Citrix XenDesktop is a suite of desktop virtualization tools designed to provide users with fast and convenient access to their Windows desktops and applications through any device. Virtual desktops mean that rather than setting up hundreds or thousands of individual computers in an enterprise, companies can instead opt to create servers with large amounts of memory, disk, and processing resources, and use virtualization to offer these resources to end users. The result of this is that users are provided with an experience that appears to be identical to having an individual desktop PC. Each user has some disk space, processor time, and memory allocated to them, as though it is present on their own physical machine, when in reality, the resources are physically present on a centralized server. This book starts by answering the basic questions you need to ask when considering XenDesktop, followed by methods of how you can properly size your server infrastructure for XenDesktop. You’ll discover how to optimize the virtual machines used in XenDesktop, how to optimize your network for XenDesktop, and how to optimize the hypervisor and the cloud. You’ll also learn how to monitor XenDesktop to maximize performance. By the end of the book, you will be able to plan, design, build, and deploy high performance XenDesktop Virtualization systems in enterprises. You will also know how to monitor and maintain your systems to ensure smooth operation.

Content Delivery Networks


A Content Delivery Network (CDN) is a large distributed system of servers deployed in multiple data centers across the globe. A CDN is the ultimate tool for acceleration as it enjoys the greatest speeds when it comes to accelerating data. You can think of a CDN as a service that you pay for, and the vendor provides and manages the acceleration appliances. You don't have to do anything except pay for the service, so no talent and skillsets are needed on your team. In addition, CDNs have hundreds, if not thousands, of appliances (similar to WOCs) in datacenters all over the world, so the service is already as close to the end user as it needs to be. CDNs implement all of the same features of an ADC and WOC and they do it on a global scale.

The organization that invented the CDN back in 1998 is Akamai. They have the largest market share and undoubtedly the largest number of enterprise customers that rely on their CDN provide the best user experience. Not only do they...
