Swift is built for scale and optimized for durability, availability, and concurrency across the entire data set. Swift is ideal for storing unstructured data that can grow without bound.

Horizon is the canonical implementation of OpenStack’s Dashboard, which provides a web based user interface to OpenStack services including Nova, Swift, Keystone, etc.

Neutron implements services and associated libraries to provide on-demand, scalable, and technology-agnostic network abstraction.

The Image service (glance) project provides a service where users can upload and discover data assets that are meant to be used with other services.

Cinder is designed to present storage resources to end users that can be consumed by the OpenStack Compute Project (Nova).

Nova supports creating virtual machines, baremetal servers (through the use of ironic), and has limited support for system containers.
