What does AWS CodeDeploy primarily do?

AWS CodeDeploy is a service designed specifically to automate the deployment of applications across various compute services such as Amazon EC2 instances, AWS Lambda, or on-premises servers. This service streamlines the deployment process, enabling developers to deploy their code quickly and reliably while managing the complexities typically associated with software releases.

With CodeDeploy, teams can define deployment strategies and manage revisions easily. The service allows rolling updates, blue/green deployments, and can automatically roll back changes if issues occur during the deployment process. This automation significantly reduces the manual steps involved and helps ensure consistent, reliable deployments across environments.

The other options relate to different aspects of cloud services: managing database services pertains to services like Amazon RDS; monitoring network traffic aligns with services like Amazon CloudWatch; and load balancing is handled by services such as Elastic Load Balancing. Each of these services focuses on a different facet of cloud infrastructure, whereas AWS CodeDeploy is specifically tailored to facilitate and enhance the deployment process of application code.
