Amazon Aurora
AWS managed Postgres / MySQL with separated storage and compute — auto-scales storage, supports zero-downtime upgrades, has Aurora Serverless v2 for spiky workloads.
Aurora separates storage (auto-replicated 6 ways across 3 AZs) from compute (writer + read replicas). Aurora Serverless v2 scales compute up and down in seconds; works well for B2B SaaS where load is bursty. Aurora supports up to 128 TB storage and is the AWS-canonical answer for "managed Postgres that I don't want to think about." Costs ~30% more than RDS but pays for itself on operational savings.
