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.
• Clustering Moodle on Multiple Servers for High Availability and Scalability.

Public clouds

• Amazon (AWS) EC2 (VMs) with auto scaling groups and managed services (Storage, Caching, Database, CI/CD).
  • Moodle Horizontal Scalable Deployment on AWS stack
  • Hosting high availability Moodle on AWS (Spanish)
  • Auto-Scaling Moodle Architecture on AWS 2015
  • Moodle with AWS Elastic Beanstalk
  • Cloud infrastructure for high concurrency slides, video 2019 Moodle MOOT Global presentation.
• Amazon (AWS) Docker containers with auto scaling groups and managed services (Storage, Caching, Database, CI/CD).
• Google (GPC) Kubernetes including automated managed micro services (Storage, Caching, Database, CI/CD, document conversions)
• Microsoft (Azure) - Deploy and Manage a Scalable Moodle Cluster on Azure
• GÉANT webinar about "Managing and running large scale Moodle system, for IT" including video recording & presentations of several different Moodle system architectures.
