Large installations

Architecture

Large scale Moodle infrastructures can be set up on different types of machines, from bare metal to compartmentalized virtual containers (or Kubernetes Pods).
In this section, we will try to share and put together some case study examples of such technological concepts of running very large scale Moodle systems.

On premise

Bare metal or Virtualization for Moodle Server_cluster setup.
