Amazon Relational Database Service (Amazon RDS) Blue/Green Deployments now supports the ability to shrink the storage volumes for your RDS database instances, allowing you to better utilize your storage resources and manage their costs. You can now increase and decrease your storage volume size based on anticipated application demands.

Previously, to shrink a storage volume, you had to manually create a new database instance with a smaller volume size, restore your current database to the newly created database instance, and switch database endpoints, often resulting in extended downtime. Blue/Green Deployments create a fully managed staging environment, or Green databases, with your specified storage size, and keep the Blue and Green databases in sync. With a few clicks, you can promote the Green databases to be the new production system in as fast as a minute, with no data loss and no changes to your application to switch database endpoints.  

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 Amazon Web Services China (Beijing) Region, operated by Sinnet and Amazon Web Services China (Ningxia) Region, operated by NWCD.  

In a few clicks, update your databases using Amazon RDS Blue/Green Deployments via the Amazon RDS Management Console. Learn more about Blue/Green Deployments on the Amazon RDS features page.
