Solaris Containers is an operating system-level virtualization technology for the Solaris operating system. It allows multiple isolated and secure operating system environments called containers to run on a single physical machine. Each container contains a complete user environment that can run applications, services, and processes independently of the other containers running on the same system. Containers are isolated from each other, have their own file system, network interfaces, and resources, and share the underlying hardware resources of the host system. Solaris Containers provide administrators with increased flexibility, efficiency, and security in managing system resources and applications.
