A commercial bank has a hybrid cloud architecture in AWS where its online banking platform is hosted. The CTO instructed its Lead DevOps Engineer to implement a suitable deployment set up that minimizes the impact on their production environment. The CI/CD process should be configured as follows: - A new fleet of Amazon EC2 instances should be automatically launched first before the actual production deployment. The additional instances will serve traffic during the deployment. - All available EC2 instances across various Availability Zones must be load-balanced and must automatically heal if it becomes impaired due to an underlying hardware failure in Amazon EC2. - At least half of the incoming traffic must be rerouted to the new application version that is hosted to the new instances. - The deployment should be considered successful if traffic is rerouted to at least half of the available EC2 instances. - All temporary files must be deleted before routing traffic to the new fleet of instances. Ensure that any other files that were automatically generated during the deployment process are removed. - To reduce costs, the EC2 instances that host the old version in the deployment group must be terminated immediately. What should the Engineer do to satisfy these requirements?
