It is made up of 3 architecture modules:

- **Runtime**: Provides the runtimes or "containers" in which code runs. These runtimes include the Gradle client, the daemon and the worker processes. This is the base module on which all other architecture modules depend.
- **Configuration**: Allows the build structure and work, such as tasks, to be specified. This includes the project model, the DSL and so on.
