​​RDS Blue/Green Deployments:

■ You can use Blue/Green Deployments to create a separate, synchronized, fully managed staging environment that mirrors the production environment. The staging environment clones your production environment’s primary database and in-Region read replicas. Blue/Green Deployments keep these two environments in sync using logical replication.
■ In as fast as a minute, you can promote the staging environment to be the new production environment with no data loss. During switchover, Blue/Green Deployments blocks writes on blue and green environments so that the green catches up with the blue, ensuring no data loss. Then, Blue/Green Deployments redirects production traffic to the newly promoted staging environment, all without any code changes to your application.
■ With Blue/Green Deployments, you can make changes, such as major and minor version upgrades, schema modifications, and operating system or maintenance updates, to the staging environment without impacting the production workload.
