A web application is running on a fleet of Amazon EC2 instances that are configured to operate in an Auto Scaling group (ASG). The instances are fronted by an Elastic Load Balancer (ELB). To enhance the system performance, a new Amazon Machine Image (AMI) was created and the ASG was configured to use the new AMI. However, after the production deployment, users complained of aberrations in the expected application functionality. A cross-check on the ELB has confirmed that all the instances are healthy and running as expected. As a solutions architect, which option would you suggest to rectify these issues and guarantee that later deployments are successful?
