LXC otherwise knows as Linux container is an operating system level virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel.
So what are the advantages? and what can I use it for? These are the first questions which popped up in my head.
For the advantages part. its fast since it depends on the physical hardware. keeps the base OS clean.
I use LXC as a web server. and yes it is really good. for me its very reliable.
