VMs are software-based systems that function as fully independent computers within a hardware system. They use software called Hypervisor to separate hardware resources like CPU, memory, and storage. Then, a virtual machine can run an alternative operating system (OS) such as Windows for business applications, and Linux for software development.
Utilizing virtual systems lowers the chance of system failure and allows you to quickly restore your data to an earlier point in time. It also enables you to test and deploy existing or new applications in a sandbox to ensure they function according to plan without disrupting production.
You can deploy multiple VMs on one physical computer thus reducing operating and capital expenses. It also eliminates the need to duplicate or backup systems, reducing the amount of data you’ll need to maintain. Cloud-based VMs allow you to access your data from anywhere with an internet connection, eliminating the requirement for storage offsite.
A VM can be used on any hardware that meets your requirements for performance, including desktops and servers. The type of Hypervisor you choose to use is a significant factor, as each has its own pros and cons for small businesses. VMware vSphere and ESX/ESXi is a popular choice. It is an enterprise-ready system with increased security, hosts that can be made with up to 128 vCPUs as well as 6 TB of RAM. role-based access, extensive logging and auditing. Microsoft Hyper-V is another popular option. It is less expensive and easier to manage than vSphere however it has the same capabilities.
