Amazon Aurora Serverless automatically starts, scales, and shuts down an Aurora database, so you don't need to manage any servers.
Many applications have intermittent or cyclical usage patterns. This creates a capacity planning dilemma, since you must either over-provision database capacity upfront and pay for resources you won’t use, or under-provision resources and risk performance problems and a poor user experience. Learn how Aurora Serverless provides an easy and cost-effective cloud database solution, where you pay only for what you actually use.
