GitHub Workflows and GitHub Actions

The service called GitHub Actions provided by GitHub (Microsoft) allows us to run arbitrary workflows on their ephemeral (temporay) servers.

CI: Often this workflow is the CI (Continuous Integration) of a project, compilingt the source code, setting ups external services, running unit- and integrations tests.

Data collection: In other cases this workflow is scheduled job collecting data and building a web site.

The service has a limited free tier for public repositories and you can buy minues for extensive running and for private repositories.

The name GitHub Actions is also used for some pre-defined building blocks one can use to create a Workflow.
