The document discusses OpenStack, an open-source software for creating private and public clouds, highlighting its development, components, and community. It covers the OpenStack Foundation, the development process involving over 2,000 contributors, and compares OpenStack with Amazon Web Services. Additionally, it provides resources for trying out OpenStack and details about community engagement.

infrastructure
● http://www.cybera.ca/

4. - 3 key areas
1. 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

9. 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?

10. What is OpenStack?

11. 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”

12. What OpenStack is not
● Not a hypervisor
○ Uses hypervisors, and supports several, but is
not a hypervisor itself
● Not a product

13. OpenStack
● Open
● Create public, private, & hybrid clouds
● Commercial support
● Thriving ecosystem

14. Platinum & Gold Members
Innovative Ecosystem

15. Diverse Use Cases
User Footprint

17. OpenStack
Foundation

18. Protecting, Empowering, and Promoting OpenStack software
and the community around it, including users, developers and the
entire ecosystem.
• Over 9,500 Individual Members, up from 5,600 at launch
• The leading Global IT companies as Gold & Platinum Members
• Board of Directors that sets strategic direction
• Project Technical Leads and a Technical Committee that are
elected from among the contributors
• User Committee to ensure the users voices are heard
The OpenStack Foundation

19. Provide a permanent legal home for OpenStack, with broad
industry support and the resources to support OpenStack’s
success
While preserving what’s working – a.k.a. the “OpenStack Way”
• Technical people making technical decisions based on merit
• Dedicated resources building the community and ecosystem
• A strong ecosystem of companies making money
• Encouraging and rewarding contribution in all forms
Foundation Approach

39. Compare/Contrast
with AWS
(& other APIs)

40. Compare/contrast AWS &
OpenStack
Q: 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...

org/wiki/Nova/APIFeatureComparison

46. OpenStack and GAE
● Project to provide GAE API
compatability:

47. OpenStack and GAE
● Code: https://github.com/stackforge/gce-
api

48. Developing on
OpenStack

49. (Typical?) Enterprise approach
● GUI Driven
● Ticket-based
● Hand-crafted
● Reserved
● Lengthy provisioning
● Scale-up
● Proprietary
● Traditional dev

50. Cloud computing approach
● API driven
● Self-service
● Automated
● On-demand
● Scale-out
● Open source
● Agile, DevOps, etc...

51. Scale out vs scale up
● Scale up: make boxes bigger
● Scale out: more boxes

52. Elastic cloud patterns
● Small failure domains
● Loose coupling
● Circuit breaker pattern
● AWS EBS could be a crutch
● Shared nothing architecture

53. 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
