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
OpenStack… Born on Arista
OpenStack has an ecosystem of 140+ participating
companies…
…and more than 1,650 individual contributors.
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
pentOS Installation…
For a multi-server operating system, the
top-of-rack switch is your BIOS.
{pentOS}TM features
{CloudKey}™
» Two-factor capable physical authentication
» Minimizes security risk of administrative logins
» Hands-free install in under 10 minutes
Null-Tier [Architecture]™
» Storage, compute and networking on every node
» Massively scalable, automated complexity

WHY DO THIS?
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
» CONVERGED NETWORKING

HEADCOUNT DOMINATES
“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
Complexity is your enemy
» A single class of node for storage,
compute, orchestration and management
» Every service is highly available
» Every service runs everywhere
» ZERO-TOUCH PROVISIONING
» ARISTA EOS
90% Automation isn’t enough
» Most of your gains are in the last 10%
» We built an auto-scaling fabric with
CloudPOST™ on Arista EOS

1 MILLION NODES
A shared roadmap
GOAL: No proprietary protocols
» OpenFlow and OpenStack Quantum:
Interconnect between physical and virtual
network layers
» Open, Extensible, Standards Based.
Goal: Global Zero-Touch
» Cloud Vision
» single point of management
» distributed control plane
» Visibility into both sides of the link
» OpenStack APIs for provisioning
