  • In the early 1960s, computer scientists working on mainframes envisioned a future where computing would be available using a utility model. The mainframe model evolved in the 90s to the modern data center. Individual servers began filling the old mainframe rooms as the growth of internet bought a surge of demand for computing. In the late 90s and early 2000s, virtualization became more common and easier to accomplish. Businesses realized they could extend a single dedicated server to provided multiple purposes for different projects and control costs and the time to acquire new hardware. In the mid- to late-2000s, the first cloud offerings began to enter the market. Now, more than 50 years since those early scientist's vision for computing, OpenStack provides open source software that enables more computing options than ever before.REF:
  • TheOpenStack Cloud Operating System is a collection of distinct services that are accessed through APIs. When installed on top of hardware, it creates a flexible and powerful cloud offering in which virtual servers can be created, modified, and deleted through a few clicks on the dashboard or through a direct call to the API.REF:

RACKSPACE® HOSTING | WWW.RACKSPACE.COM “If computers of the kind I have advocated become the computers of the future, then computing may someday be organized as a public utility just as the telephone system is a public utility … The computer utility could become the basis of a new and important industry.” - John McCarthy, American Computer Scientist, MIT Centennial, 1961 4 Brief History of Computing Want to be an OpenStack Contributor?

    12. 12. RACKSPACE® HOSTING | WWW.RACKSPACE.COM How to Contribute Want to be an OpenStack Contributor 12 1. Join - Prove You are You • Create Launchpad account • Upload SSH keys • Join the Foundation (free) • Verify it works on 2. Work Files - Get your Git On • Clone an OpenStack Repo • Setup git-review • Edit, test locally • Submit a patch • Get it reviewed 3. Review – Extra Eyes • Add inline comments • Click Review - OR – • Get local copy of the patch • Patch your patch • Run tests, edit • Push it back to Just 3 simple steps!
    13. 13. RACKSPACE® HOSTING | WWW.RACKSPACE.COM When Simple isn’t Easy – Git Want to be an OpenStack Contributor? 13 • Git has a Learning Curve • It may or may not make perfectly intelligent people feel dumb • You may or may not learn how to do something, not use it for a week, and feel like you’re starting over again • Tutorials online may or may not assume you already know basics of version control and git branch strategy • It may or may not be hard when you’re missing something “obvious” to folks with git experience
    14. 14. RACKSPACE® HOSTING | WWW.RACKSPACE.COM When Simple isn’t Easy - Reviews Want to be an OpenStack Contributor 14 • To merge, a patch must be reviewed – Various voting and non-voting jobs – +1 from two Project cores (+2) • Those smart people you get to work with? They have opinions. Usually strong ones. • Your Great Idea may not fit with the release cycle goals or the direction of the project. • Your approach to content creation (coding, writing, translation, etc) may be different than someone else’s and you may be blocked as a result • Core Reviewers are an endangered species who often don’t have time to be “nice” in comments (but they are!) Don’t give up! The review process is a great way to learn python and OpenStack from experienced developers who want you to succeed.
    15. 15. RACKSPACE® HOSTING | WWW.RACKSPACE.COM • Join in through launchpad and the Foundation • Sign up for some mailing lists and join an IRC channel (or ten) • Observe the community for a while and see where you are “pulled” • Find a mentor to work with in your area of interest • Ask LOTS of questions “We may actually have enough developers right now. What we need are all those other types of people.” Paraphrase of Russell B., former Nova PTL, from Mid- Cycle Meetup in Utah 15 What’s Next Want to be an OpenStack Contributor?
