The Advantages of Virtualisation

Virtualsation4Simply put virtualisation is about consolidation – using fewer physical computers to run the same number of servers. The flexibility of a virtualised server environment allows SMBs to benefit form enterprise-grade services such as, high availability and disaster recovery services that were previously out of reach. Virtualisation basically involves making one physical computer act as if it were several computers. These virtual computers can each run an independent operating system and interact with the other network devices as if they were standalone physical computer.

Think of the traditional server room as a group of friends around a restaurant table. Each person gets one plate of food, regardless of how hungry they are. Some people will have food left over, while others will still be hungry. If someone wants more food, or an unexpected guest arrives, they need to pay for another meal – even though there’s plenty of food elsewhere on the table. This is your typical small to medium business server room, where the physical computers can’t easily share resources such as processing power or storage. Virtualisation in a server room is the equivalent of ordering a banquet, with each person taking as much or as little food as they require. If one person is particularly hungry, everyone else can forgo a little of their food rather than ordering a new dish. Better yet, if unexpected guests arrive the food can be easily redistributed without the need to pay for another meal. This way no-one goes hungry, food doesn’t go to waste and the overall bill is lower than if everyone had ordered their own meal.

The consolidation aspect of virtualisation means you’re immediately talking cost savings in terms of hardware, rack space, cooling and power consumption. The true benefits of virtualisation for SMEs are in its reliability and flexibility. One benefit of virtualisation is that it paves the way for affordable disaster recovery and high availability, not just for one application but for every application that’s part of the virtualised infrastructure.

Virtualisation cuts to the very heart of an organisation’s IT infrastructure and tends to touch on almost every aspect of the business. Virtualisation offers the SMB much of the competitive advantages which were previously only accessible to large corporations without the restrictive cost.

When people think about virtualisation they tend to think about servers, but virtualisation technologies spread to cover storage, desktop environments and even individual applications. Of these, virtualised storage is perhaps the key component if customers want to get the most from their virtualised environment. Virtualisation and the platform around it make it very easy for businesses to grow without major disruptions. It does that firstly by being able to provision servers very quickly.
