How to build a lightweight system container cluster

You will learn how working in this environment:

LXD, the system container manager, developed by Canonical and shipped by default with Ubuntu, makes it possible to create many containers of various Linux distributions and manage them in a way similar to virtual machines (VMs) but with lower overhead costs associated with them.

Unlike VMs, containers have the benefit of using a shared kernel such as; kernel security updates in Ubuntu, Livepatch support, minimal memory footprint, ease of sharing resources and an extremely low CPU usage/wakeups at idle.

This whitepaper explores the use of LXD containers as part of a team development environment, effectively setting up a shared lab on physical hardware or in the cloud.

You will learn how working in this environment:

Reduces the time spent by team members getting a functional work environment
Makes it easy to collaborate with colleagues, accessing their containers if needed
Makes it possible to access the work environment of team members who are on leave
Better use and control of resources by using shared systems
Easy to implement snapshots and backups, huge time savers when a mistake happens
