DAmazon Aurora Serverless v2 — scales compute automatically with usage and pauses when idle
Answer & Solution
Correct answer: D. Amazon Aurora Serverless v2 — scales compute automatically with usage and pauses when idle
Aurora Serverless scales compute to match demand and bills per ACU-second; ideal for spiky / dev workloads. Provisioned at fixed large size pays for idle. Self-hosted EC2 even worse. Glacier isn't an OLTP store.
