Blue-green deployment is a pattern for performing software upgrades. By setting up the latest version of your application on an identical clone of your production application stack, traffic can be switched, near instantaneously, from the current production stack to the new one as soon as the test suite and the business determine it is appropriate. Though this is an old technique, infrastructure automation and resources in the cloud make it worth reconsidering.
