Which deployment options does GitLab Review Apps support?

GitLab Review Apps support the deployment of applications to various environments as scripted in the .gitlab-ci.yml file. This functionality allows teams to create dynamic environments for testing and reviewing merge requests in isolation. By defining the deployment process in the .gitlab-ci.yml file, developers can specify where and how the application should be deployed, whether it's to a staging server, a cloud environment, or even a local instance.

This versatility is essential for modern development practices, as it enables continuous integration and continuous deployment (CI/CD). Review Apps facilitate collaboration since team members can view the current state of an application in real-time, ensuring that all aspects of the feature or bug fix can be visually inspected before merging into the main codebase.

The other deployment options indicated do not capture the full scope of what GitLab Review Apps can do. Options that limit the functionality to only FTP, only cloud infrastructures, or only serverless architectures miss the broader capability of supporting a variety of environments, catering to diverse development workflows and deployment strategies. By leveraging the scripting capability in .gitlab-ci.yml, developers can customize their Review Apps to fit their specific requirements, thus maximizing the flexibility and utility of their deployment processes.
