Question

An e-commerce web application that shares session state on-premises is being migrated to AWS. The application must be fault tolerant, natively highly scalable, and any service interruption should not affect the user experience. What is the best option to store the session state?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Store the session state in Amazon ElastiCache. Amazon ElastiCache provides in-memory caching (Redis/Memcached) to reduce latency and offload the database. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
