Both projects, and others, are open source solutions (OSS) on GitHub and storing their releases there. It happens that GitHub uses AWS to store our release artefacts.
If we look at the ALM-Rangers/Migrate-assets-from-RM-server-to-VSTS project, we’ll note that its pipeline is hosted by ❶ Visual Studio Team Services (VSTS) on Azure. When we ❷ commit code to the GitHub repository, the continuous integration build is ❸ triggered, followed by ❹ automated tests, storage of the ❺ release back to GitHub, which rolls it out to the ❻ Amazon cloud.
It’s a great showcase of using two cloud computing solutions to implement a CI/CD pipeline for an open source solution.
