Fuel's current use cases, architecture and next steps
•

Fuel is open source initiative which provides great automation and flexibility for: * CentOS and Ubuntu provisioning on bare metal servers * Disk partitioning, including software RAIDs. Support of hardware RAIDs is in the roadmap * Complex network configurations, including VLANs, GRE and bonding * Network verification (VLANs, DHCP) before deployment * Automated deployment of OpenStack components and Ceph * Health Check - a set of short-running tests to ensure functionality of deployed environment

- 7. User Experience: UI (Live Demo)
- 8. User Experience: CLI (Live Demo) ● Covers everything we can do via UI ● Allows even more
- 10. ● Written on Python ● Exposes internal data via REST API ● Concentrates up to 90% of deployment logic ● Transforms user input (UI, CLI) into deployment data (JSON) ● Keeps tasks status and all information in DB ● Uses SQLAlchemy, Alembic for DB access and migrations Components: Nailgun
- 11. Components: Naily & Astute
- 12. ● Naily consumes messages sent by Nailgun ● Naily & Astute are both written in Ruby ● Astute uses MCollective RPC ● Has bindings to provisioning ● Tracks progress of deployment, provisioning ● Supports operations (adding/removing nodes) ● Small in comparison with Nailgun Components: Naily & Astute
- 13. Components: OSTF (Health Check)
