Learn how you can use Amazon ElastiCache to easily deploy a Memcached-compatible, in-memory caching system to speed up your application performance. We show you how to use ElastiCache to improve your application latency and reduce the load on your database servers. We'll also show you how to build a caching layer that is easy to manage and scale as your application grows.

6. Example:
First Time:
Cache = {}
Step 1: Look in the cache. It’s empty; ‘cache miss’
Step 2: Get the value from the DB; update the cache

7. Example:
Second Time:
Cache = {‘John Smith’ : ‘206-555-1212’}
Step 1: Look in the cache. Return the result; ‘cache hit’
Step 2: Until John’s number changes, we don’t hit the DB

8. Example:
Cache Invalidation:
Cache = {‘John Smith’ : ‘206-555-1212’} (out of date)
Step 1: Update Database with John’s new number
Step 2: Update the cache with John’s new number
Cache = {‘John Smith’ : ‘415-555-1212’}
