AWS Aurora Serverless v2: Architecture and Performance Guide

Aurora Serverless v2 is what v1 should have been. I don’t say that lightly — I ran v1 in production for two years and spent more time fighting its scaling quirks than actually building features. The pausing, the cold starts, the inability to add read replicas. It was a product that promised serverless databases and delivered something that felt like a managed instance with extra steps. When v2 landed, I was skeptical. AWS has a habit of slapping “v2” on things that are marginally better. But I migrated a production PostgreSQL workload from RDS provisioned to Aurora Serverless v2 last year, and it genuinely changed how I think about database scaling strategies. The scaling is fast, granular, and — this is the part that surprised me — it doesn’t drop connections when it scales. That alone makes it a different product entirely.
