VMs are software environments that act as fully independent computers running on an existing hardware system. They make use of software known as a Hypervisor to separate hardware resources such as CPU, memory, and storage. A virtual machine can use a different operating system, for instance, Windows for business applications or Linux for software development.
Using virtual systems reduces the risk of system failure and allows you to quickly restore your data to a previous point in time. You can also test and deploy new or legacy applications using a sandbox in order to ensure that they work as expected, without disrupting production.
You can deploy multiple VMs on the same physical computer, reducing your operating and capital costs. It also eliminates duplicate backup systems and reduces the amount of data you must keep. Cloud-based VMs allow you to access your data from anywhere with an internet connection, eliminating the need for offsite storage.
A VM can be operated on any device that meets the requirements for performance of your company, which includes desktops and servers. Each Hypervisor has pros and cons that are essential for small businesses. VMware vSphere and ESX/ESXi is the most popular choice. It is a business-ready option that comes with enhanced security hosts with up 6 TB of RAM and 128 vCPUs. They also have role-based accessibility, extensive logging, and auditing. Microsoft Hyper-V is another popular alternative. It is cheaper and more manageable than vSphere but has the same capabilities.
