Amazon RDS Blue/Green Deployments reduces downtime to under five seconds

Amazon Relational Database Service (Amazon RDS) now supports faster Blue/Green Deployments switchover, reducing your primary database, or writer node, upgrade downtime to typically five seconds or lower for single-Region configurations. Blue/Green Deployment creates a staging environment (Green) to test changes while keeping production (Blue) safe, enabling seamless switchover that requires no application endpoint changes.

Your database writer instance downtime during switchover varies based on your connection method. For single-Region configurations, applications connecting directly to the database endpoint experience typically five seconds or lower downtime, while those using the AWS Advanced JDBC Driver typically see two seconds or lower due to eliminated DNS propagation delays. You can use Amazon RDS Blue/Green Deployments for deploying changes to production, such as major version database engine upgrades, maintenance updates, and scaling instances.

Support for faster RDS Blue/Green Deployments switchover for single-Region configurations is available for Amazon Aurora and Amazon RDS database engines including PostgreSQL, MySQL, and MariaDB in all AWS regions.

In a few clicks, update your databases using RDS Blue/Green Deployments via the Amazon RDS Console or Amazon RDS CLI. Learn more about RDS Blue/Green Deployments and the supported engine versions here.
