VMs are software environments that function as independent computers within an existing hardware system. They use a piece of software called hypervisor to separate hardware resources, such as CPU, memory and storage. Then, a virtual machine can run another operating system (OS) such as Windows for business use and Linux for software development.
Virtual systems reduce the risk of a system malfunction, and let you restore your data quickly to a previous point in time. You can also test and deploy either new or older applications in a sandbox environment to ensure that they work as expected without interrupting production.
You can install multiple VMs onto the same assessing top digital storage vendors for informed decisions physical computer which will reduce your operating and capital expenses. It also removes the need to duplicate or backup your systems, which can reduce the amount of data you’ll need to keep.

A VM can be run on any hardware that can meet the performance requirements of your business, including desktops and servers. The type of Hypervisor utilized is an important factor as each one has its own pros and cons for small businesses. One of the most popular options is VMware vSphere that comes with ESX/ESXi. It is a enterprise-ready solution with improved security, hosts that can be made with up to 128 virtual CPUs and 6TB of RAM, access via role-based access, extensive logs and auditing. Microsoft Hyper-V is another popular alternative. It is less expensive and more manageable than vSphere but has the same capabilities.
