A virtual machine (VM) is an computer system that emulates on the top of a physical host machine. It appears like a real computer to the user and can run various operating systems, like Windows Linux or macOS. VMs are a popular choice because they allow multiple operating systems to be hosted on a single server, which can result in significant savings for businesses.

Typically, a VM is typically a “guest” on the host computer, which provides hardware resources like processors, memory and hard disk drives. This allows businesses to put multiple VMs on the same host computer and allows IT infrastructures to expand and shrink as needed. This flexibility helps IT teams to be less busy working on software updates, as they can manage each physical device instead of having to manage them all.

There are two primary types of VM hypervisors one being Type 1 and the other Type 2. Type 1 hypervisors have better performance since they operate directly on the host system, without the requirement of a full-blown operating system. Type 2 hypervisors direct each VM request to the host operating system. This can reduce processing speed and add cost.

In addition to scalability, virtual machines can also help improve IT security and disaster recovery. Virtual machines are not tied to the underlying physical hardware. This makes it easier to restore a VM in the event of a natural disaster or outage. This can prevent data loss and downtime, which can have a direct impact on your business’s bottom line.
