In my day-to-day job, I support teams at different organizations and help them with their AWS challenges. One of the teams I recently supported was using Amazon ElasticCache for Redis as a storage/caching layer for their primary workload. They were validating their production setup and testing several failure scenarios. In this article, I will share some of the lessons learned. Keep in mind that the cases described in this article are very context-specific and might not reflect your use case, so my advice is to always do your own tests.
Initial Architecture
The team built a REST-based service by using API Gateway, AWS Lambda, and Amazon ElastiCache for Redis.
