The title of the presentation might be a bit off. We gave about a 30 minute introduction to OpenStack, and then about a 30 min demo on installing the Ghost blogging platform using Chef in an OpenStack cloud.

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?

8. Contributed to 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
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
20. Expecting 4000+ in Hong Kong: November 5-8, 2013
OpenStack Summit Attendee Growth
24. 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

27. 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

Open Development Process
Technology Platform
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...

43. OpenStack & AWS components
OpenStack Amazon Web Services
Horizon AWS Console
Nova EC2
Keystone IAM
Neutron Networking / Virtual Private Cloud
Glance AMIs
Cinder EBS
Swift S3
Ceilometer Usage / Billing
Heat CloudFormation
Trove RDS
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
55. How to try/use OpenStack
● DevStack - http://devstack.org
● TryStack - http://trystack.org
● Search in github... vagrant openstack
● Example public OpenStack based clouds in US:
○ RackSpace - trial: http://developer.rackspace.com/devtrial/
○ HPCloud
○ Internap
● Example public OpenStack based clouds in Canada:
○ CloudA
○ ???
● CANARIE - http://canarie.ca
