VMs are software-based environments that function as independent computers on an existing hardware system. They use software called Hypervisor to separate hardware resources such as 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.
Virtual systems decrease the likelihood of a system failure and allows you to restore your data quickly back to a previous date. You can also test and deploy new or legacy applications in a sandbox environment to make sure that they function according to plan without disrupting production.
The ability to run multiple VMs on one server means that you will require less equipment and lower operational and capital costs. It also eliminates duplicate or backup systems and reduces the amount of data you must keep. Cloud-based VMs allow you to access your data anywhere with an Internet connection, which eliminates the requirement for storage offsite.
A VM can be operated on any device that meets the performance requirements of your company, which includes servers and desktops. The type of Hypervisor that is used is an important factor as every solution has its own pros and cons for small businesses. The most popular option is VMware the vSphere platform with ESX/ESXi. It is an enterprise-ready system with enhanced security, hosts that are able to be created with up to 128 vCPUs and 6TB of RAM, the ability to access roles, extensive logging and auditing. Another option that is gaining popularity is Microsoft Hyper-V. It is less expensive and more manageable than vSphere but has the same capabilities.
