A virtual machine is a computer that has been emulated that runs on an actual host. It appears to be a real computer to the user and runs various operating systems, such as Windows Linux or macOS. VMs are a popular choice because they allow multiple operating systems to be hosted on the same server, which could result in significant cost savings for companies.
Typically every VM is the “guest” of a host machine that provides hardware resources such as processors memory, memory, hard disk drives and network connections. As a result, businesses can put several VMs on the same host machine, giving flexibility to allow IT infrastructure to grow or shrink as required. This flexibility can also help reduce the time IT teams are able to spend on deploying and maintaining software updates, since they can do it on a server-by-server basis rather than having to manage each individual physical machine.
There are two major types of VM hypervisors: Type 1 and Type 2. Type 1 hypervisors are faster because they run directly on a host device without the need for a full-blown OS. Type 2 hypervisors pass each VM request through the host operating system, which could slow the processing speed and result in additional overhead.
Virtual machines can enhance IT security, as well as disaster recovery. Since a virtual environment is independent of the hardware it runs on which makes it much quicker to restore data from the VM than a physical machine in case of a failure or natural catastrophe. This can reduce data loss and downtime, which could directly impact your company’s bottom line.
