A virtual machine is a computer that has been emulated that runs on the physical host. It appears to the user as a genuine computer system, and can run various operating systems such as Windows, Linux or macOS. VMs are very popular because they allow for multiple environments to be run on a single computer, which can help businesses save a lot of money.

Typically the case, each VM is the “guest” of host machines that provide hardware resources such as processors memory, memory, hard disk drives and network connections. In this way, businesses can install multiple VMs on the same host machine, allowing flexibility that allows IT infrastructure to expand or shrink as required. This flexibility allows IT teams to spend less time making changes to software since they can manage each physical device instead of having to manage them all.

There are two types of VM Hypervisors which are Type 2 and 1. Type 1 hypervisors perform better because they run directly on a host computer without the need for a full-blown operating system. Type 2 hypervisors pass each VM request through the host operating system, which could slow down processing speed and add additional costs.

Alongside scalability virtual machines can also improve IT security and disaster recovery. Since virtual environments are independent of the underlying hardware that makes it easier to restore data from a VM than physical machines in the event of an outage or natural disaster. This can reduce data loss and downtime, which can have a direct impact on your company’s bottom line.
