VMware ESXi is a type of software that allows you to run multiple “virtual machines” on a single physical computer. A virtual machine is essentially a computer that runs within another computer.
With ESXi, you can create and manage virtual machines, each of which can run its own operating system and applications, just like a real physical computer. These virtual machines are completely isolated from one another, so if one crashes or has an issue, it won’t affect any of the other virtual machines.
ESXi is used in a lot of different contexts, but one common use case is in server virtualization. By running multiple virtual machines on a single physical server, you can maximize the use of the server’s resources, which can be more cost-effective than buying and maintaining multiple physical servers.
ESXi is designed to be lightweight and efficient, which makes it a popular choice for virtualization in data centers and other enterprise environments. It also has a lot of features for managing and monitoring virtual machines, such as live migration, which allows you to move a running virtual machine from one physical server to another without any interruption in service.
Overall, VMware ESXi is a powerful tool for creating and managing virtual machines, and it has become an essential part of many organizations’ IT infrastructure.
