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

Amazon RDS Blue/Green Deployments

Amazon RDS now supports faster Blue/Green Deployments switchover, reducing primary database 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.

Downtime during switchover varies based on connection method:

• Direct database endpoint: Typically five seconds or lower downtime
• AWS Advanced JDBC Driver: Typically two seconds or lower downtime

You can use RDS Blue/Green Deployments for deploying changes to production, such as major version database engine upgrades, maintenance updates, and scaling instances.

Support is available for Amazon Aurora and RDS database engines including PostgreSQL, MySQL, and MariaDB in all AWS regions.

What to do

• Update your databases using RDS Blue/Green Deployments via the Amazon RDS Console or Amazon RDS CLI
