Container-based virtualization for Linux that's open source allows for the deployment of several secure and isolated Linux containers, also referred to as VEs or VPSs, on a single physical machine, which optimizes server utilization while preventing application conflicts. Each of these containers operates and functions just like an independent server; they can be rebooted on their own and possess root access, as well as their own users, IP addresses, memory, processes, files, applications, system libraries, and configuration files. This technology not only enhances efficiency but also provides greater flexibility in managing resources across various applications.
