Operating System Virtual Machine Types
A software application that builds a virtual computer environment is known as a virtual machine (VM). This environment can run its own operating system and apps and is separate from the host machine. Testing software, running legacy programs, and creating and testing new operating systems are just a few of the many uses for virtual machines.
System VMs and process VMs are the two basic categories of virtual machines.
System virtual machines are complete virtual machines that are capable of running an entire operating system. They are produced by a hypervisor, a piece of software that controls the host computer's resources and offers the virtual machine (VM) a virtualized environment.
Lightweight virtual machines that can only run one process are called "Process VMs." They are produced by a virtual machine monitor (VMM), a kind of hypervisor that solely controls the resources used by the process that is operating inside the VM.
There are numerous types of VMs available, each with unique advantages and disadvantages. Popular virtual machine systems include:
VMware is a commercial virtual machine platform with many features and support options.
VirtualBox is an open-source virtual machine platform with a sizable user base that is free to use.
Windows Server comes with a hypervisor called Microsoft Hyper-V.
Oracle VM VirtualBox is an open-source virtual machine platform with a sizable user base that is free to use.
Your individual requirements will determine the kind of VM you select. A system VM is the ideal choice if you need to execute an operating system in its entirety. A process VM is a preferable alternative if you only need to run one process.
Advantages of Virtual Machines
Utilizing virtual machines has numerous advantages, including:
Flexibility: VMs are particularly flexible since they are simple to create and destroy. To run an outdated legacy application or test a new piece of software without affecting your current systems, you can establish a new virtual machine (VM).
VMs can be segregated from one another, which increases their security. The other VMs won't be impacted if one VM is compromised.
Cost savings: You can reduce your hardware expenses by using virtual machines. One physical server can host several virtual machines, which can cut down on the number of servers you need to buy.
Summary
Virtual machines are strong tools that have many applications. VMs are an excellent choice if you're searching for a versatile, secure, and affordable way to run several operating systems on a single computer.
