A six-month cohort in PostgreSQL, SQL Server, cloud, and infrastructure as code. Real work on real systems, every task graded and recorded, and a credential an employer can verify in ten seconds.
The ground every database runs on: the terminal, systemd, storage, networking. This is the free on-ramp month.
Architecture, MVCC and vacuum, WAL, roles and pooling, backup and PITR, replication, and high availability with Patroni.
T-SQL and DMVs, recovery models, security and TDE, Always On - plus the translation table that maps it to PostgreSQL.
Terraform and Ansible. Provision databases from an empty cloud account and promote schema through dev, qa, and prod.
Managed and self-managed. RDS, Aurora, and Azure SQL: what the provider absorbs, failover behaviour, and the cost shape.
Monitoring as code, incident command, a heterogeneous migration, and a capstone estate - all recorded as verified evidence.
Phase 0
Linux, the terminal, Git, and SQL beyond joins. Free.
Phase 1
Architecture through replication and high availability, on real servers.
Phase 2
T-SQL, recovery, Always On, and the cross-engine translation table.
Phase 3
Backup, failover, tuning, and security in both engines, under pressure.
Phase 4
RDS, Aurora, Azure SQL, Terraform, Ansible, observability as code.
Phase 5
A heterogeneous migration, capacity forecasting, and an on-call incident.
Capstone
Build it from code, operate it for weeks, and defend it to a panel.
You pass an assessment at the end of each phase before the next unlocks.
Start the free Linux month on real servers. Finish it, and you can apply to the next cohort.
