A company utilizes AWS Elastic Beanstalk to oversee their IT infrastructure on the AWS Cloud and is planning to deploy a new version of its application to EC2 instances. During the deployment process, they require that some instances continue to handle requests with the old application version, while other instances begin serving requests with the new application version, until the deployment is fully completed.
Which deployment strategy fulfills this requirement without resulting in additional costs?
Explanation:
With Elastic Beanstalk, you can quickly deploy and manage applications in the AWS Cloud without having to learn about the infrastructure that runs those applications. Elastic Beanstalk reduces management complexity without restricting choice or control. You simply upload your application, and Elastic Beanstalk automatically handles the details of capacity provisioning, load balancing, scaling, and application health monitoring.
