What does a deployment pipeline allow for in AWS?

A deployment pipeline in AWS facilitates the process of continuous integration and continuous deployment (CI/CD) of code changes. This means that it automates the steps involved in integrating code changes from multiple developers, testing those changes, and deploying them to production environments seamlessly.

Through the use of a deployment pipeline, teams can ensure that code changes are consistently merged, tested for any issues, and deployed to production in a systematic way. This not only enhances the speed and frequency of software releases but also improves the reliability and quality of the codebase by making testing and deployment processes automated and repeatable. By embracing this methodology, organizations can respond more quickly to changes in requirements or user feedback, thus fostering an agile approach to software development.

The other options focus on manual or static approaches, which do not leverage the automation and efficiency that a CI/CD pipeline offers. Making changes manually or one-time configurations does not support the dynamic nature of modern software development practices that deployment pipelines are designed to facilitate.
