Cheat sheet
This cheat sheet summarizes the main key points from this chapter:
- Amazon ElastiCache is a fully managed caching service.
- ElastiCache supports two different caching technologies, Redis and Memcached.
- Redis has two modes, cluster mode enabled and cluster mode disabled.
- ElastiCache supports read replicas on both engines.
- ElastiCache can be provisioned both inside and outside of a VPC to meet your needs.
- Redis supports sharding and complex data types and can run in Multi-AZ.
- Caching can feature TTL, which ages out older records to save space and to ensure that the latest data is available in the cache.
- Techniques such as write-through and lazy loading can be used to control the speed that the cache updates, balancing new data and saving space.
