LXD

LXD is a system that allows you to run multiple isolated, lightweight virtual environments called containers on a single physical machine. These containers behave like separate computers, each with their own applications and files, but share the underlying hardware resources. LXD manages these containers efficiently, offering a way to deploy, organize, and control multiple environments easily. It’s useful for development, testing, or running different services without needing full virtual machines, making resource use more efficient while providing flexibility and security in managing diverse workloads.
