Using ElastiCache to Improve DynamoDB Performance and Cut Costs
In this lab, we are presented with a site that is struggling under load because the backing DynamoDB table has had its read and write provisioning drastically reduced to avoid incurring significant cost. To correct this, we will provision an ElastiCache cluster and modify the Lambda functions in the site architecture to implement a simple caching scheme that returns the site to a functional state.
