A company's Chief Information Security Officer (CISO) has tasked a solutions architect with enhancing the current CI/CD practices to ensure that patch deployments to the company's web application can occur rapidly with minimal downtime when vulnerabilities are identified. Additionally, the company must have the capability to swiftly revert changes in the event of errors. The web application is currently deployed on a fleet of Amazon EC2 instances behind an Application Load Balancer. The application's source code is hosted on GitHub, and an AWS CodeBuild project has been set up for building the application. The company plans to utilize AWS CodePipeline to initiate builds from GitHub commits using the existing CodeBuild project. What CI/CD configuration should be implemented to meet these requirements?
