ElastiCache

Summary#

Amazon ElastiCache allows you to set up, run, and scale popular open-source compatible in-memory data stores like Redis or Memcached. ElastiCache ultimately runs atop EC2 instances with pre-configured software and are prefixed with "cache." and are referred to as Nodes.

Pricing Dimensions#

Dimension	Description
Node Usage	You are charged for the amount of hours your ElastiCache nodes run.

Reserved Instances#

ElastiCache Nodes do have Reserved Instances that can give you significant savings. Reserved Instances are covered as a general concept found here.

Typically, as ElastiCache nodes remain on for longer durations and aren't members of auto-scaling groups, they are good candidates for cost savings via Reserved Instances.

Savings Plans#

ElastiCache Nodes are not covered under AWS Savings Plans.
