What Azure Taught Us About Designing for SQL at Scale
Article summary
What Azure Taught Us About Designing for SQL at Scale Before we migrated to Azure SQL, we assumed our database patterns were solid. After all, queries were optimized, indexes carefully chosen, deadlocks rare. But the moment we hit the cloud, those assumptions didn’t hold. Latency became a real variable. Load patterns changed. And some of our favorite tricks backfired. This is the story of how Azure didn’t break our database-but showed us how brittle our habits really were. Where Our Patterns Fell Apart 1. We Optimized for Throughput, Not Predictability Under load, our high-throughput logic (batch inserts, merge operations, bulk reads) began creating blocking issues. Writes blocked reads Lock escalations increased Retry loops masked bad contention In Azure SQL, shared compute resources made spiky load more expensive than sustained volume. 2.
