Question

A company has a front-end application that runs on four Amazon EC2 instances behind an Elastic Load Balancer (ELB) in a production environment that is provisioned by AWS Elastic Beanstalk. A developer needs to deploy and test new application code while updating the Elastic Beanstalk platform from the current version to a newer version of Node.js. The solution must result in zero downtime for the application. Which solution meets these requirements?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Perform an immutable update to deploy the new application code to new EC2 instances. Serve traffic to the new instances after they pass health checks. Amazon EC2 provides resizable virtual servers when you need full control of the operating system.
