Step 2: Evaluate the Five Primary Delivery Models
Once you understand the different user segments that need to be served in your desktop virtualization implementation, you can begin evaluating how the different delivery models available stack up against your requirements. There are five primary delivery models for desktop virtualization. Server-side virtualization: Terminal services Virtual hosted desktops Client-side virtualization: Operating system image streaming Application streaming and virtualization Client-side virtual container Each model provides some degree of central management, and each has advantages and trade-offs. Keep in mind that the best solution for a given organization typically combines more than one model. But always choose the minimum number of delivery models.
Desktop Virtualization Delivery Models at a Glance
Model Terminal Services Virtual Hosted Desktops Server-side Operating System Image Streaming Client-side Application Streaming and Virtualization Client-side Client-Side Virtual Container Client-side
Server- or client-side Best suited for
Environments where a critical business application is needed across a broad spectrum of users and when application compatibility and operating system support may be a challenge.
Environments where users have an entire desktop image that needs to be accessed from multiple locations, and the operating system, applications, and workload of that image are stable and predictable. Citrix XenDesktop* Microsoft Virtual Desktop Infrastructure* VMware View*
Environments where security is critical and no user information needs to persist after a session. Also beneficial when local support is a challenge or when uptime is critical.
Environments Appropriate for most where application environments; model is and license deployment/ still evolving. management are critical.
