Description: The isolation mechanism in containerization technologies refers to the techniques implemented to ensure that containers operate independently from each other and from the host system. This isolation is fundamental for the security and stability of applications running in containers, as it prevents one container from affecting the operation of others or the underlying operating system. The main features of this mechanism include the use of lightweight virtualization technologies, which allow containers to run in virtualized environments, as well as the implementation of namespaces and cgroups in Linux. Namespaces ensure that each container has its own isolated environment for processes, users, and networks, while cgroups limit and prioritize resource usage of the system. This approach not only enhances security but also optimizes performance, allowing multiple containers to run efficiently on a single host. In a world where data security and application integrity are paramount, the isolation mechanism becomes an essential component for any modern containerization solution.
