Amazon Virtual Private Cloud (Amazon VPC) with ElastiCache
The Amazon Virtual Private Cloud (Amazon VPC) service defines a virtual network that closely resembles a traditional data center. When you configure your Amazon VPC you can select its IP address range, create subnets, and configure route tables, network gateways, and security settings. You can also add a cache cluster to the virtual network, and control access to the cache cluster by using Amazon VPC security groups.
This section explains how to manually configure an ElastiCache cluster in an Amazon VPC. This information is intended for users who want a deeper understanding of how ElastiCache and Amazon VPC work together.
