What should be done next to complete the update?
Redirect to the new environment using Amazon Route 53
Select the Swap Environment URLs option
Replace the Auto Scaling launch configuration
Update the DNS records to point to the green environment
Explanations:
Redirecting to the new environment using Amazon Route 53 is not necessary in this case, as the blue/green deployment strategy can be handled through Elastic Beanstalk’s environment URL swap feature.
The correct next step in a blue/green deployment in AWS Elastic Beanstalk is to use the “Swap Environment URLs” option, which switches the traffic from the blue (old) environment to the green (new) environment.
Replacing the Auto Scaling launch configuration is unnecessary, as the new environment should already have the desired configuration. The focus should be on routing traffic, not launch configurations.
Updating DNS records manually is not needed when using Elastic Beanstalk’s built-in “Swap Environment URLs” functionality, which handles the routing of traffic automatically.
I design that the answer is:
Select the Swap Environment URLs option
I calculate that the answer is:
