How do you implement blue-green deployment on AWS?

Asked on Nov 26, 2025

Answer

Blue-green deployment on AWS is a strategy to minimize downtime and reduce risk by running two identical environments — blue (current) and green (new version). AWS Elastic Beanstalk, AWS CodeDeploy, or Kubernetes on EKS can facilitate this process by allowing seamless traffic switching between environments.

Set up two identical environments (blue and green) using AWS Elastic Beanstalk or AWS CodeDeploy.
Deploy the new application version to the green environment while the blue environment continues serving traffic.
Test the green environment thoroughly to ensure it meets all requirements and functions correctly.
Switch the traffic from the blue environment to the green environment using Route 53 or an Elastic Load Balancer.
Monitor the new environment for any issues and keep the old environment available for rollback if necessary.

Additional Comment:

Blue-green deployments help achieve zero-downtime updates and facilitate quick rollbacks if needed.
Consider using AWS CodePipeline to automate the deployment process for continuous integration and delivery.
Ensure proper monitoring and logging are in place to detect any issues during and after the deployment.
Evaluate costs as maintaining two environments can increase resource usage temporarily.
