Agenda
● 11:50 - What is OpenStack?● Foundation● How is it made?● Releases and components● Compare contrast w/ AWS, APIs...● Developing on OpenStack● How to try OpenStack● Community● 12:25 - Grab lunch● 12:30 - David demo starts
● Cybera is a not-for-profit organization responsible for overseeing the development of Alberta’s cyber-infrastructure
● http://www.cybera.ca/
- 3 key areas1. Designing and operating Cyberanet, Alberta’s public
ultra high-speed network
2. Piloting research and innovation projects that apply the power of this network
3. Fostering business growth by opening up this network to entrepreneurs working on bringing technology to market
Questions
1. How many of you are developers?2. Enterprise? Startups? Non-profit? SMB?3. Used Amazon Web Services (AWS)?4. Run their business on AWS or IaaS or Paas?5. Heard of OpenStack?6. Used OpenStack? 7. Deployed OpenStack?8. Contributed to OpenStack?
What is OpenStack?
OpenStack is
● Open source software for building private and public clouds
● Arguably most successful open source project, after Linux
● 1000+ developers in 80 countries● “Giant ball of mostly Python”
What OpenStack is not
● Not a hypervisor ○ Uses hypervisors, and supports several, but is
not a hypervisor itself● Not a product
OpenStack
● Open● Create public, private, & hybrid clouds● Commercial support● Thriving ecosystem
Platinum & Gold MembersInnovative Ecosystem

• Dedicated resources building the community and ecosystem
• A strong ecosystem of companies making money
• Encouraging and rewarding contribution in all forms
Foundation Approach
Expecting 4000+ in Hong Kong: November 5-8, 2013
OpenStack Summit Attendee Growth

OpenStack Development(how it’s made)
OpenStack development
● 115,206 commits made by 2,130 contributors
● representing 1,766,546 lines of code● took an estimated 500 years of effort
(COCOMO model) ● Development model is meritocracy
Time-Based Release Cycle
New software release every six months, with interim milestones
Twice Yearly Design Summits
Immediately following software release to plan next version Sessions led by developers and Project Technical Leads
Broad Contributions
1000 developers, from over 50 companies worldwide
Elected Leadership
Developers elect their own Project Technical Leaders

Compare/Contrastwith AWS(& other APIs)
Compare/contrast AWS & OpenStackQ: Who will win between GCE, AWS, and OpenStack? Which is better, ect...A: “Who will win between Century 21, Home Depot, and a lumber mill?”
NOTE: API compatibility is a philosophy on its own...

Developing onOpenStack
(Typical?) Enterprise approach
● GUI Driven● Ticket-based● Hand-crafted● Reserved● Lengthy provisioning● Scale-up● Proprietary● Traditional dev
Cloud computing approach
● API driven● Self-service● Automated● On-demand● Scale-out● Open source● Agile, DevOps, etc...
Scale out vs scale up
● Scale up: make boxes bigger● Scale out: more boxes
Elastic cloud patterns
● Small failure domains● Loose coupling● Circuit breaker pattern● AWS EBS could be a crutch● Shared nothing architecture
OpenStack Swift - Object Storage
● Not a file system & not block storage● Highly available, durable, distributed,
eventually consistent, unstructured storage accessed via a REST-ful http API!
● Scale-out: If possible, drop the shared file system, use object storage
