Pantheon is a great Drupal and WordPress hosting. It has a nice UI for deployments. However, doing deployments from UI can have some issues.
Problems we solve:
- Only one person on the team can do deployments to Test / Prod environment in Pantheon
- Deployments need manual steps so that they can be error-prone
- There is no easy way to see what code is currently in Production unless you log in to Pantheon and check it there.
