Re: Virtualization
Benefits of Technology
Confidential
This memo is to inform the company about the changes that we want to undergo. With technology moving as fast as it is. It is our job to stay in front of the curve so we can run our business effectively. With that being said I would like to move our company into the virtualization era.
Benefits of Virtualization
Server Consolidation
It is not unusual to achieve 10:1 virtual to physical machine consolidation. This means that ten server applications can be run on a single machine that had required as many physical computers to provide the unique operating system and technical specification environments in order to operate. Server utilization is optimized and legacy software can maintain old OS configurations while new applications are running in VMs with updated platforms.
Although a server supporting many VMs will probably have more memory, CPUs, and other hardware it will use little or no more power and occupy the same physical space reducing utilities costs and real estate expenditures.
Testing and development
Use of a VM enables rapid deployment by isolating the application in a known and controlled environment. Unknown factors such as mixed libraries caused by numerous installs can be eliminated. Severe crashes that required hours of reinstallation now take moments by simply copying a virtual image.
Dynamic Load Balancing and Disaster Recovery
As server workloads vary, virtualization provides the ability for virtual machines that are over utilizing the resources of a server to be moved to underutilized servers. This dynamic load balancing creates efficient utilization of server resources.
Disaster recovery is a critical component for IT, as system crashes can create huge economic losses. Virtualization technology enables
