Using OpenStack With Fog
The document outlines OpenStack, an open-source cloud infrastructure that runs on non-proprietary hardware and is governed by the OpenStack Foundation. It includes a brief history of its inception, prominent projects like Nova and Swift, and the use of the Fog library for Ruby to interact with OpenStack services. Additionally, it addresses concerns over global compute workload distribution and invites participation in OpenStack development.

- 5. OpenStack birth “ LaunchedNova. Apache-Licensed Cloud Computing, in Python. It’s live. it’s buggy, it’s beta. Check it out “ - Joshua McKenty blog post, summer 2010 @jmckenty (Joshua McKenty)
- 6. OpenStack birth • NASAAimes CTO • Worked with Microsoft/Google on some NASA visualizations • Preferred Google’s approach • NASA needs a cloud! @kemp (Chris Kemp)
