Amazon Relational Database Service (Amazon RDS) Blue/Green Deployments now support managed initialization of Green storage volumes that accelerates the loading of storage blocks from Amazon S3. This ensures that the volumes are fully performant prior to switchover of the Green databases. Blue/Green Deployments create a fully managed staging environment, or Green database, by restoring the Blue database snapshot. The Green database allows you to deploy and test production changes, keeping your current production database, or Blue database, safer.
Previously, you had to manually initialize the storage volumes of the Green databases. With this launch, RDS Blue/Green Deployments will proactively manage and accelerate the storage initialization for your green database instances. You will be able to view the progress of storage initialization using the RDS Console and command line interface (CLI). Managed storage initialization of the Green databases is supported for Blue/Green deployments created for RDS for PostgreSQL, RDS for MySQL, and RDS for MariaDB engines.
Amazon RDS Blue/Green Deployments are available for Amazon RDS for PostgreSQL major versions 12 and higher, RDS for MySQL major versions 5.7 and higher, and Amazon RDS for MariaDB major versions 10.4 and higher.
In a few clicks, update your databases using Amazon RDS Blue/Green Deployments via the Amazon RDS Console. Learn more about RDS Blue/Green Deployments and the supported engine versions here.
