AWS CodeDeploy is a fully managed deployment service that automates software deployments to a variety of compute services, including Amazon EC2, AWS Fargate, AWS Lambda, and on-premises servers. It simplifies the process of rapidly releasing new features by automating the code deployment process, which helps to avoid downtime during application deployment and handles the complexity of updating applications. CodeDeploy is a core component of a continuous integration and continuous delivery (CI/CD) pipeline on AWS, directly fulfilling the requirement to release application changes in an automated way.

A. Amazon AppFlow is a fully managed integration service that automates secure data flows between SaaS applications and AWS services, not for deploying application code.

C. AWS PrivateLink provides private, secure connectivity between VPCs, AWS services, and on-premises networks. It is a networking service, not a deployment automation tool.

D. Amazon EKS Distro is a Kubernetes distribution used to build and run Kubernetes clusters. It is the platform, not the service that automates application releases onto it.
