The Amazon ElastiCache web service allows developers to deploy, operate, and scale an in-memory cache in the cloud. Using ElastiCache, developers can retrive information from an in-momory caching system as opposed to disk-based databases.
The API provides functionality such as allowing users to launch a Cache Cluster selecting a Cache Cluster Name, Cache Node Type and Number of Nodes best suited to their nodes. If additional capacity is needed, users can add more Cache Nodes to their Cache Cluster via the API. The API uses RESTful calls and responses are formatted in XML.
