How would you automate blue-green deployment in AWS with IaC?
Blue-green deployments allow seamless application updates with minimal downtime. How would you automate a blue-green deployment in AWS using Infrastructure-as-Code (IaC)? Describe any tools and sample code you’d use.

Answer 1

To deploy a blue-green deployment to AWS, services such as AWS Elastic Beanstalk can be used in conjunction with load balancers or EC2 Auto Scaling groups. Resource provisioning and switching can be performed by tools like Terraform or AWS CloudFormation. 

With this setup, you can adjust target group weights to control traffic, effectively performing a blue-green switch.
