The Lab
Where I practise running MongoDB, six days a week.
MongoDB University
The Atlas Administrator path (13 skills, CRUD and indexing through sharding, reliability, security and encryption), then the Node.js Developer path. Both with labs.
MongoDB Atlas
A free M0 cluster every day; a dedicated tier for a few hours when a backup or encryption lab needs it.
Self-managed
MongoDB 8 on my PC and a 3-member replica set on Linux VMs, for failover and restore drills.
MongoDB 8.0 in Action
Arek Borucki's third edition (2025), plus infrastructure as code with Pulumi.
