Everyone is eager to virtualize their working environment to
take advantage of the abstraction layer it provides. Some may
require resource isolation for enhanced security, others may
need development environments for testing and debugging.
Whatever your needs are, virtualization will save you resources
through utilizing them more efficiently. This is done by
exploiting synergies built on proven technologies, improving
availability and reducing downtime, adding scalability through
duplication and gaining a certain degree of hardware
independence. Gains from virtualization The gains from
virtualization are rapidly being uncovered, however the most
obvious savings are in maintenance. Maintaining ten virtual
instances of a service, application, or system, that are all
very similar to each other, is much easier than maintaining ten
separate machines, with ten different operating system
installations, patch levels, security updates, etc. Keeping all
of your virtual instances on one machine is much more resource
