LXC is in between a VM and a pure application container. It will take up more resources than a pure container, but unlike a VM use as much memory as needed. It will provide a full kernel and OS (albeit it must be Linux). Unlike a VM, LXC container will have access to the resources and speed of the hardware without needing to emulate hardware. LXC is wrapped by Warden and the foundation for Cloud Foundry. Even if you are just interested in Docker or Cloud and not yet ready to give up your ssh console, start here. Learning LXC, you'll also really understand how Cloud Foundry, Docker and generally Cloud concepts actually works. There is also value in then using LXD to learn how to build at your own bare metal, higher level Cloud infrastructure like Kubernetes.
