In short: Server virtualization is all about migrating physical servers onto a virtual platform that enables the sharing of computing resources on less hardware. With today’s server technology we are able to achieve a consolidation ratios of 40:1. However, we never put all of our eggs in one basket, so our smallest configurations include at least two servers with centralized storage for high availability.
Server virtualization is defined as the partitioning of a physical server into fewer virtual servers. Instead of requiring a separate computer for each server, dozens of virtual servers can co-reside on the same virtualized host server.
BENEFITS OF SERVER VIRTUALIZATION
Server virtualization has many benefits. For example, it lets each virtual server run its own operating system and each virtual server can also be independently rebooted of one another. Server virtualization also reduces costs. First, less hardware is required so that alone saves a business money. It also utilizes resources to the fullest so it can also save on operational costs (e.g. using a lower number of physical servers reduces hardware maintenance). Server virtualization is also important for data centers. It increases the data center’s space utilization efficiency and promotes energy efficiency through reduced energy consumption and a reduction in server room heat — thereby lowering cooling costs.
In short: Desktop virtualization is all about migrating the computing resources off the desktop and onto a server platform simplifying the management and regaining control of the end user. If architected and implemented properly the end user will experience no difference in his/her everyday computing needs. What the end user will gain is the ability to access his/her applications and data anywhere, anytime, and from any device. When we add mobile device management to the solution we are able to create a separation between personal and business applications on a single device. This results in less devices for the end user and easier management for IT.
BENEFITS OF DESKTOP VIRTUALIZATION
Desktop virtualization offers advantages over computers operating as individual units as each virtual desktop will not require its own hardware, operating system and software. Also, using desktop virtualization lower cost of deploying applications and will reduce downtime in the event of a server or hardware failure.
