What is Blue-Green Deployment in AWS?

Question

Could someone tell me what is Blue-Green Deployment in AWS?

Answer 1

Blue-Green deployment is an application release model, that will help in gradually transferring user traffic from a previous version of the app or microservice to a newer version, both of which are running in production. The Blue deployment is the older version, and the Green represents the newer version. In AWS, the applications get deployed in the AWS Elastic Beanstalk environment, having two separate, in-production environments Blue and Green, which increases both availability and reduces risk at the same time. So, what happens is, Blue environment, handles all the oncoming traffic until CI/CD Pipeline architecture creates a nearly identical clone i.e., green environment, and swaps the URLs between the two environments.
