Operating-system-level virtualization file systems and create and roll back snapshots of the entire system state. Several companies offer container hosting and container image registry services: Operating-system-level virtualization Operating-system-level virtualization, also known as containerization, refers to an operating system feature in which the kernel allows the existence of multiple isolated user-space instances.
