Linux Namespaces
Linux Namespaces are a kernel feature that provides process isolation by partitioning system resources such as process IDs, network interfaces, mount points, and user IDs into separate, isolated instances. They allow processes to have their own view of the system, enabling lightweight virtualization and containerization. This technology is fundamental to tools like Docker and LXC, which use namespaces to create isolated environments for applications.
Developers should learn Linux Namespaces when working with containerization, system-level virtualization, or building secure, isolated environments for applications. They are essential for creating containers that run multiple processes in isolation without the overhead of full virtual machines. Use cases include developing containerized applications, implementing sandboxing for security, and managing multi-tenant systems where resource separation is critical.
