A Practical Guide to Azure PostgreSQL: Migration, Replicas, and Tuning ☁️🐘

Short summary

A hands-on walkthrough of the Microsoft Applied Skills assessment for Azure Database for PostgreSQL, covering Entra ID authentication, VNET private endpoints, diagnostic logging, pg_restore migration, read replicas in paired regions, and EXPLAIN-based query tuning. The author shares a real-world B-tree index size error during restore and explains why non-critical index failures don't invalidate data restores. Practical takeaways emphasize private endpoints first, understanding migration logs, and analyzing before scaling compute.

• •Configure dual auth, private endpoints, and diagnostic logging on Azure PostgreSQL Flexible Server
• •Restore sample database via pgAdmin; non-critical B-tree index failures don't block data restore
• •Create read replicas in paired regions and use EXPLAIN plans to fix query bottlenecks without scaling compute
