Which AWS service can be used for continuous delivery?

AWS CodePipeline is specifically designed for continuous delivery. It automates the process of building, testing, and deploying code every time there is a code change, thus enabling continuous integration and deployment. By integrating various AWS services and third-party tools, CodePipeline orchestrates the workflow for software releases, allowing developers to focus on writing code while the service manages the deployment process.

Continuous delivery relies on streamlined pipelines that ensure code updates are delivered to users quickly and reliably. AWS CodePipeline meets these requirements by allowing teams to create a series of automated actions that can include source code retrieval, building, testing, and deployment processes without manual intervention, leading to shorter release cycles and a more efficient workflow.

The other services mentioned serve different purposes. AWS CodeDeploy is used for automating the deployment of applications to compute services, but it doesn’t manage the overall pipeline. AWS CloudFormation is primarily focused on infrastructure as code, allowing users to define and provision AWS infrastructure, rather than the continuous delivery of application code. AWS Lambda allows code execution in response to events but is not a comprehensive continuous delivery service. Hence, AWS CodePipeline stands out as the correct answer for continuous delivery.
