Elasticache

Amazon ElastiCache is a cloud-caching service that increases the performance, speed, and redundancy with which applications can retrieve data by providing an in-memory database caching system.

aws.elasticache.CPUUtilization

The percentage of CPU utilization.

When reaching high utilization and your main workload is from read requests, scale your cache cluster out by adding read replicas. If the main workload is from write requests, scale up by using a larger cache instance type.

DynamoDB

DynamoDB is a fully managed proprietary NoSQL database service that supports key-value and document data structures and is offered by Amazon as part of the Amazon Web Services portfolio. Amazon CloudWatch aggregates the DynamoDB metrics at one-minute intervals.

In DynamoDB, provisioned throughput requirements are specified in terms of capacity units: Read Capacity unit and Write Capacity unit. A unit of read capacity represents one strongly consistent read per second for items up to 4 KB in size. One write capacity unit represents one write per second for items up to 1 KB in size. Larger items will require more capacity. You can calculate the number of units of read and write capacity by estimating the number of reads or writes required per second and multiplying by the size of the items rounded up to the nearest KB.

For more information, see the Amazon DynamoDB documentation.

Simple Queue Service (SQS)

Amazon Simple Queue Service (Amazon SQS) is a pay-per-use web service for storing messages in transit between computers. Developers use SQS to build distributed applications with decoupled components without having to deal with the overhead of creating and maintaining message queues.
