Which system provides a way to automate the deployment of applications?

Continuous deployment is a system designed to automate the release of applications into production environments. This practice allows for code changes to be automatically deployed without manual intervention, which significantly accelerates the development lifecycle and ensures that new features, bug fixes, and updates reach users more quickly. By integrating a Continuous Integration/Continuous Deployment (CI/CD) pipeline, developers can push their code updates, and the system manages testing and deployment seamlessly, ensuring that every change is automatically validated and released once it passes all necessary checks.

In contrast, a build server is responsible for compiling code and running initial tests, but it does not encompass the entirety of the deployment process as Continuous Deployment does. Version control primarily manages code changes and collaboration, ensuring developers can track and revert to previous versions but does not automate deployment. A testing framework is primarily focused on validating code quality and functionality through tests but doesn’t directly automate the release process.

Overall, Continuous Deployment stands out as the most comprehensive approach to automating application deployment within a modern development workflow.
