A Linux Container is an operating-system-level virtualization environment for running multiple isolated Linux systems on a single Linux control host (Wikipedia LXC). It can be also defined as a lightweight VM but extremely fast and easy to deploy.

There is not much overhead and therefore it's the perfect solution for effective use of resources.

No extra kernel boot is necessary on startup resulting in a super fast boot.

Linux Containers are introduced in Proxmox VE 4.0 and support the Proxmox Storage Model.
