This section provides information about virtual machines and containers. What to read next Virtual Machines (ESXi)Virtual machines are the logical containers in which applications and guest operating systems run. By design, all VMware VMs are isolated from one another. This isolation enables multiple VMs to run securely while sharing hardware, and provides both their ability to access hardware and their uninterrupted performance. Modern Applications (Containers)A container encapsulates an application in a form that is portable and easy to deploy. Containers can run without changes on any compatible system, in any public or private cloud, in a traditional enterprise computing environment, or an edge computing device.
