Introduction to Serverless Databases for MySQL and PostgreSQL
summary
Amazon Aurora Serverless v2 claims instant in‑place scaling measured in 0.5 ACU increments, supports MySQL 8 and PostgreSQL 13, and keeps six storage copies across three AZs with typical storage replication latency <10 ms; global database replication advertises <1s cross‑region replication and failover under a minute. Clusters attach up to up to 15 low‑latency read replicas, memory evictions use LFU/LRU heuristics for safe scale‑down, and monitoring through RDS Performance Insights guides minimum/maximum ACU choices (recommend at least 2 ACU for insights).
