Blue/Green Deployments - Overview of Deployment Options on AWS

Blue/Green Deployments

A blue/green deployment is a deployment strategy in which you create two separate, but identical environments. One environment (blue) is running the current application version and one environment (green) is running the new application version. Using a blue/green deployment strategy increases application availability and reduces deployment risk by simplifying the rollback process if a deployment fails. Once testing has been completed on the green environment, live application traffic is directed to the green environment and the blue environment is deprecated.

A number of AWS deployment services support blue/green deployment strategies including Elastic Beanstalk, OpsWorks, CloudFormation, CodeDeploy, and Amazon ECS. Refer to Blue/Green Deployments on AWS for more details and strategies for implementing blue/green deployment processes for your application.
