AWS CloudFormation ElastiCache
Overview
Use this skill to model ElastiCache infrastructure with CloudFormation without turning SKILL.md into a full service manual.
Focus on the delivery decisions that matter most:
- choosing the right cache topology
- placing the cache safely inside a VPC
- configuring availability, encryption, and exports for downstream stacks
Use the bundled references/ documents for larger production templates and service-specific detail.
When to Use
Use this skill when:
- creating a Redis or Memcached cache tier with CloudFormation
- deciding between
AWS::ElastiCache::CacheCluster and AWS::ElastiCache::ReplicationGroup
- configuring subnet groups, parameter groups, and security groups for application access
- adding snapshots, maintenance windows, encryption, and Multi-AZ behavior
- exporting cache endpoints to application or platform stacks
- reviewing cache changes for replacement risk, downtime, or operational cost
Typical trigger phrases include cloudformation elasticache, redis replication group, memcached cluster, , and .
