What Is Amazon ElastiCache?
Welcome to the Amazon ElastiCache User Guide. ElastiCache is a web service that makes it easy to set
up, manage, and scale a distributed in-memory cache environment in the cloud. It provides a
high-performance, resizable, and cost-effective caching solution, while removing the complexity associated
with deploying and managing a distributed cache environment.
With ElastiCache, you can quickly deploy your cache environment, without having to provision hardware
or install software.You can choose from Memcached or Redis protocol-compliant cache engine software,
and let ElastiCache perform software upgrades and patch management for you automatically. For enhanced
security, ElastiCache runs in the Amazon Virtual Private Cloud (Amazon VPC) environment, giving you
complete control over network access to your cache cluster. With just a few clicks in the AWS Management
Console, you can add resources to your ElastiCache environment, such as additional nodes or read
replicas, to meet your business needs and application requirements.
Existing applications that use Memcached or Redis can use ElastiCache with almost no modification;
your applications simply need to know the host names and port numbers of the ElastiCache nodes that
you have deployed. The ElastiCache Auto Discovery feature lets your applications identify all of the nodes
in a cache cluster and connect to them, rather than having to maintain a list of available host names and
port numbers; in this way, your applications are effectively insulated from changes to cache node
membership.
ElastiCache has multiple features to enhance reliability for critical production deployments, such as
automatic detection of and recovery from cache node failures. ElastiCache also works together with other
Amazon Web Services (such as Amazon EC2, CloudWatch, and Amazon SNS) to provide a secure,
high-performance and managed in-memory caching solution.
