This document provides an introduction to OpenStack, including: - OpenStack is an open-source software platform for building private and public clouds with components that provide compute, storage, and networking capabilities. - The OpenStack architecture is modular with components that can be used individually or together, including compute, networking, block storage, image service, object storage, identity service, and dashboard. - Challenges of deploying OpenStack include needing skills in Linux, cloud infrastructure, and OpenStack architecture, as well as getting operations and engineering teams familiarized with OpenStack.
