Server Virtualisation – What is it?
Server virtualisation is not a new technology although is becoming more popular as business's work to reduce costs and maximise efficiency. Server virtualisation is based on the partitioning of a physical server into smaller virtual servers to help maximize your server resources. In server virtualisation the resources of the server itself are hidden, or masked, from users, and software is used to divide the physical server into multiple virtual environments, called virtual or private servers. This is in contrast to dedicating one server to a single application or task.
Common Uses of Server Virtualisation
Virtualisation can be used in all business environments from single server business up to large enterprise with 50+ severs to hosting companies that run 100’s of multiple servers as a business. This functionality helps to deliver a more stable computing environment, at a lowest total cost of ownership. It also allows for simplified deployment and testing of new applications and importantly allows for robust disaster recovery solutions that gets the business up and running quickly – less than an hour following a major disaster.
Benefits of Server Virtualisation
Server virtualisation 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 virtualisation also reduces costs because less hardware is required so that alone saves business's money on power to run the servers and cooling. Server virtualisation also conserves space through consolidation as several machines can be consolidated into one server running multiple virtual environments. 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, and can reduce or allow redeployment of IT resource to business critical projects rather than support and maintenance).
