The Virtualization Practice

Tag Archive for Contention

With virtualization technology we, the system administrators, have a lot of tools available to make our day to day operation and administration of our environments easier to work with and speeds up the time it takes to do a lot of administration tasks. Take for example the ability we have to add resources to a virtual machine. You can add processors, memory and or increase disk space within a matter of minutes and very little downtime. On a physical host you would need to purchase the hardware first and wait for it to arrive and then schedule the downtime to add the resources to the machine. This speed and power can be both a blessing and a curse. Once application owners understand how easy it is to add resources to the virtual machines then comes the requests for additional resources any time the application owners think there is the slightest bit of need for any additional resources.
