Pros
- Auto-scaling compute based on query complexity
- Pay-per-query when idle (RPU-seconds)
- Zero infrastructure management
- Same SQL and BI tools as provisioned Redshift
- Data sharing across serverless and provisioned clusters
Cons
- ✕Managed databases cost more than self-hosted for predictable, steady workloads
- ✕Cold starts on serverless databases (Aurora Serverless) can impact latency-sensitive apps
- ✕Vendor lock-in risk — migrating large databases out of AWS is non-trivial
