Virtualisation is the single most effective way to reduce IT expenses whilst boosting efficiency and agility – not just for large enterprises, but for small and midsize businesses too.
What is Virtualisation?
Simply put, it’s the process of creating a virtual, rather than physical, version of something. Virtualisation can apply to computers, operating systems, storage devices, applications, or networks. However, server virtualisation is at the heart of it.
IT organisations are challenged by the limitations of today’s x86 servers, which are designed to run just one operating system and application at a time. As a result, even small data centres have to deploy many servers, each operating at just 5 to 15 percent of capacity – highly inefficient by any standard.
Virtualisation uses software to simulate the existence of hardware and create a virtual computer system. Doing this allows businesses to run more than one virtual system – and multiple operating systems and applications – on a single server. This can provide economies of scale and greater efficiency.
Using server virtualisation, a company can maximise the use of its server resources and reduce the number of servers required. The result is server consolidation, which improves efficiency and cuts costs.
Benefits of Virtualisation
Virtualisation can increase IT agility, flexibility and scalability, while creating significant cost savings. Workloads get deployed faster, performance and availability increases and operations become automated, resulting in IT that’s simpler to manage and less costly to own and operate.
- Reduce capital and operating costs
- Deliver high application availability
- Minimise or eliminate downtime
- Increase IT productivity, efficiency, agility and responsiveness
- Speed and simplify application and resource provisioning
- Support business continuity and disaster recovery
- Enable centralised management
- Build a true software-defined data centre
It’s Not Cloud Computing
Cloud computing is not the same thing as virtualisation; rather, it’s something you can do using virtualisation. Cloud computing describes the delivery of shared computing resources (software and/or data) on demand through the internet. Whether or not you are in the Cloud, you can start by virtualising your servers and then move to cloud computing for even more agility and increased self-service.
