5. What is openstack?
» Founded by NASA and Rackspace
» The open source cloud computing platform
» Feature-rich and massively scalable
» Powers cloud storage, compute, and networking
» A world-wide open source collaboration

6. OpenStack… Born on Arista

7. OpenStack has an ecosystem of 140+ participating
companies…
…and more than 1,650 individual contributors.

8. Introducing {pentOS} TM
» Piston Enterprise OS:
» A hardened cloud operating system built on
OpenStack ™
» Optimized for secure and easy operation of enterprise
private clouds
» Fully supports interoperability with other OpenStack ™
powered public and private cloud solutions
» Delivers the power and flexibility of public
clouds, behind your firewall

13. WHY DO THIS?

15. Network trumps computing
» “The Mobility Gap – 4X over a decade.” –
Kenneth Church
» “…by 2020, our Digital Universe will be
44 TIMES AS BIG as it was in 2009…”
» LESSON: Use Converged Networking

16. » CONVERGED NETWORKING

17. Cloud Economics – The Cards

• Network • Power • IT Admin
• Storage • Floor space • Consulting
• Compute • Transit • Lost work
• Software • Compliance

18. HEADCOUNT DOMINATES

19. “In praise of techno-austerity: The technology
industry seems to be coming round to the idea
that less is more.”
- The Economist, Jun 10th 2010
“Complexity is holding our industry back right
now. A lot of what is bought and paid for doesn't
get implemented because of complexity. Maybe
this is the industry's biggest challenge.”
- Ray Lane, Kleiner Perkins Caufield & Byers

20. Complexity is your enemy
» A single class of node for storage,
compute, orchestration and management
» Every service is highly available
» Every service runs everywhere

24. A shared roadmap
1 MILLION NODES

25. GOAL: No proprietary protocols
» OpenFlow and OpenStack Quantum:
Interconnect between physical and virtual
network layers
» Open, Extensible, Standards Based.

26. Goal: Global Zero-Touch
» Cloud Vision
» single point of management
» distributed control plane
» Visibility into both sides of the link
» OpenStack APIs for provisioning
