Blue-Green Deployment

Blue-Green deployment is a technique used to reduce risk and delay in continuous integration. It uses an exact copy of production environment, where new changes can be deployed and production testing can be done. After running successful tests, we can just point router to this copy and make it production. In case of any error in system after this step, we can roll back by re-pointing router to old application instance. This process reduces the production downtime during migration and expedite any rollback operation in case of error in production to last successful build.
