# Overview

Cached services allow you to use a pool of pre-created infrastructure elements that can be attached to newly created environments at any time. For example, resources like Amazon RDS may take on the order of hours to start up, when you specify a snapshot to start from. Gallery allows you to maintain a bank of warm services that can be attached to your environments.
