Of course, the usual caveat about Murphy's Law applies here; even the most thorough testing can miss bugs that are intermittent in nature or that surface only in certain circumstances. Moreover, SMBs need to beware that testing everything in this manner can be an expensive endeavor given their relative limited resources. Ultimately, care must be taken not to let update/patch testing to cause an impediment to the quick deployment of time sensitive security patches.
Move to Desktop Virtualization
One increasingly popular facet of virtualization is client virtualization, which entails running the entire desktop environment within a centralized server. With all processing is done within the server, client devices are typically thin clients that serve as an end node to connect I/O peripherals such as keyboard, mouse, a display, audio connectors and even USB ports over the LAN.
While there are similarities between client and server virtualization in terms of the basic infrastructure required, businesses should not make the mistake of mixing them together due to differing objectives and technical considerations. The term "virtual desktop infrastructure" or VDI is used describe the hardware and software components required to support a desktop virtualization deployment.
In view of the complexity of obtaining a good virtual desktop experience, you may be interested to know that a number of vendors have emerged to offer turnkey VDI solutions to help SMBs get started. For now, you can read more about VDI in this article titled 2012: Virtual desktops are all the rage.
