Amazon ElastiCache improves application performance by allowing you to retrieve information from an in-memory caching system.

High-performance, distributed memory object caching system, intended for use in speeding up dynamic web applications.

Memcached

Global Datastore sets up cross region replication between primary and secondary cluster.

ElastiCache Cluster Client is a Memcached client that supports Auto Discovery which allows it to automatically discover Nodes. This means that scaling the number of nodes in a cluster no longer requires updating the static list of endpoints in the client configuration.

ElastiCache Cluster Client

When significant events happen for a cluster, ElastiCache sends notification to a specific Amazon SNS topic. By monitoring for key events, you can know the current state of your clusters and, depending upon the event, be able to take corrective action.

Events

A subnet group is a collection of subnets (typically private) that you can designate for your clusters running in an Amazon Virtual Private Cloud (VPC) environment. If you create a cluster in an Amazon VPC, you must specify a subnet group. ElastiCache uses that subnet group to choose a subnet and IP addresses within that subnet to associate with your nodes.

Subnet groups

Provides a lower price when committing to a 1 or 3 year term for supported node types by way of the following offering types; all up front, partial up front and no upfront.

Reserved nodes

Amazon ElastiCache automatically monitors your fleet of Redis OSS clusters and nodes to apply service updates as they become available. Typically, you set up a predefined maintenance window so that ElastiCache can apply these updates. However, in some cases you might find this approach too rigid and likely to constrain your business flows. With self-service updates, you control when and which updates are applied. You can also monitor the progress of these updates to your selected Redis OSS clusters in real time.

Service updates

Amazon ElastiCache uses parameters to control the runtime properties of your nodes and clusters. Generally, newer engine versions include additional parameters to support the newer functionality.

Parameter groups

Amazon ElastiCache clusters running Redis OSS can back up their data. You can use the backup to restore a cluster or seed a new cluster. The backup consists of the cluster's metadata, along with all of the data in the cluster. All backups are written to Amazon Simple Storage Service (Amazon S3), which provides durable storage. At any time, you can restore your data by creating a new Redis OSS cluster and populating it with data from a backup.
