+* *Crunch*: Crunch is the orchestration system for running [Common Workflow Language](https://www.commonwl.org) workflows. It is
+designed to maintain data provenance and workflow
+reproducibility. Crunch automatically tracks data inputs and outputs
+through Keep and executes workflow processes in Docker containers. In
+a cloud environment, Crunch optimizes costs by scaling compute on demand.
+
+* *Workbench*: The Workbench web application allows users to interactively access
+Arvados functionality. It is especially helpful for querying and
+browsing data, visualizing provenance, and tracking the progress of
+workflows.
+
+* *Command Line tools*: The command line interface (CLI) provides convenient access to Arvados
+functionality in the Arvados platform from the command line.
+
+* *API and SDKs*: Arvados is designed to be integrated with existing infrastructure. All
+the services in Arvados are accessed through a RESTful API. SDKs are
+available for Python, Go, R, Perl, Ruby, and Java.
