2022/11/28 - Amazon Relational Database Service - 4 new api methods
Changes This release enables new Aurora and RDS feature called Blue/Green Deployments that makes updates to databases safer, simpler and faster.
Creates a blue/green deployment.
A blue/green deployment creates a staging environment that copies the production environment. In a blue/green deployment, the blue environment is the current production environment. The green environment is the staging environment. The staging environment stays in sync with the current production environment using logical replication.
You can make changes to the databases in the green environment without affecting production workloads. For example, you can upgrade the major or minor DB engine version, change database parameters, or make schema changes in the staging environment. You can thoroughly test changes in the green environment. When ready, you can switch over the environments to promote the green environment to be the new production environment. The switchover typically takes under a minute.
For more information, see Using Amazon RDS Blue/Green Deployments for database updates in the Amazon RDS User Guide and Using Amazon RDS Blue/Green Deployments for database updates in the Amazon Aurora User Guide .
