This article offers a review of storage options for serverless on AWS for databases, microservices, IoT, and storage synchronization. It offers on-demand computing power for one-time scripts, bulk processes, and application back-ends.

For many functions, statelessness is not a problem but for applications, some form of data persistence is required. Cloud services are attached via service API and can provide storage that scales smoothly with app traffic.
