Containerization with LXC

Abstract

Not too long ago, we used to deploy applications on a single server, scaling up by adding more hardware resources—we called it "the monolith approach." Achieving high availability was a matter of adding more single purpose servers/monoliths behind load balancers, more often than not ending with a cluster of under-utilized systems. Writing and deploying applications also followed this monolithic approach—the software was usually a large binary that provided most, if not all of the functionality. We either had to compile it from source and use some kind of installer, or package it and ship it to a repository.
