<ul><li>1.NASA NebulaPast, Present, and Future<br />A Story in Three Parts<br />James F. Williams<br />CIO, NASA Ames Research Center<br />April 26, 2011<br /></li></ul> <p>2. One of the first cloud computing platforms built for the Federal Government by the Federal Government<br />Publicly launched IaaS with the White House as the first customer in production<br />Basis of OpenStack Compute, aka Nova<br />There are over 300 users across nine NASA Centers + JPL + HQ<br />NASA Nebula Cloud Computing<br />3. Lots Been Said About Nebula.some of it crazy<br />What do you get when you combine cloud computing and data center containers? You get NASAs Nebula, the space agencys new data powerhouse, which provides on-demand computing power for NASA researchers. <br />http://www.datacenterknowledge.com/archives/2009/12/02/nasas-nebula-the-cloud-in-a-container/<br />The world will end if we dont do this.<br />Former NASA Center CIO<br />Will create world peace.<br />Future Miss America<br />Putting the Space in Rackspace<br />Start-up Co-founder<br />This will can help solve NASAs real compute issues<br />New NASA Center CIO<br />Because we need more developers<br />Well known cloud architect<br />4. Tell you the unofficial Story of how NASA Nebula started..from my perspective.I was there for most of it.Ive blacked out for some of it.<br />Where we are today and what NASA is doing<br />Our vision for NASA Nebula for the future<br />Getting Past the Hype<br />5. NASA Nebula, Part 1<br />6. 1000s of other NASA websites<br />"A long time ago in a US Agency far, far away.... (well, DC is far)"<br />www.nasa.gov<br />Photo Credit:www.starwars,com<br />Photo Credit:www.starwars,com<br />7. Why wouldnt they join NASA.gov?<br />www.nasa.gov<br />Perception:<br />Control<br />Issues with CMS<br />Flexibility<br />Cost <br />Photo Credit:www.starwars,com<br />8. Theres a better way to do this<br />Problem:How do we get these web developers to stop building out their own sites?<br />Solution:Give Developers a better alternative to status quo<br />NASA.net was born<br />9. NASA.net<br />Setting:Basement of NASA Ames Research Center (ARC) Building 200, in an old conference room<br />Imagine:Small team of developers working on Platform as a Service<br />Code hosting<br />Continuous integration<br />Bug Tracking<br />Best Practices in code development<br />Making unicorns happy across NASA<br />10. But after working on Platform as a Service prototypes<br />Learned in order to run a web application framework properly as a service, we need elastic infrastructure <br />11. Over Indian Food in Mountain View<br />Joshua McKenty pitched the cloud idea to us.I just ate curry.<br />We decided build out an IaaS capability just to support NASA.net<br />Chris didnt pay for lunch.<br /> Photo Credit:http://www.tandooribistrosj.com/<br />12. Problem<br />Us:Thanks!We need funding..<br />Everyone:Great Idea!<br />13. 14. Why?<br />FY09:<br />Line item for cloud?<br />FY06:<br />Plan FY09 Budget<br />How do we fund IT innovation? <br />15. At the same time, White House cloud first initiative was gaining traction<br />Federal CIO, VivekKundraevangelized the idea of Cloud Computing <br />In coordination with the data center consolidations, agencies should evaluate the potential to adopt cloud computing solutions by analyzing computing alternatives for IT investments in FY 2012. Agencies will be expected to adopt cloud computing solutions where they represent the best value at an acceptable level of risk.http://www.whitehouse.gov/sites/default/files/omb/assets/memoranda_2010/m10-19.pdf<br />16. A team said No<br />They just said No.<br />A wise woman said. Drop back.Punt.And wait to get the ball back.<br />17. We didnt have any money but we had popsicle sticks and string so we started anyway. <br />Josh liked Indian food and was friends with Jesse<br />These guys were the first IT hippies I met.I gave them free headbands.<br />There eventually was a guy named Vish(from Iowa? Really?) and someone from ZZTop(Hes got cloud, and he knows how to use them..)<br />I bought cases of Red Bull to cover up the fact I didnt have money for chairs.<br />But ARC is creative..<br />18. USASpending.gov<br />Then the White House wanted to use our cloud.Then they came to ARC and some NASA officials were there...<br />Somehow we got a container and a couple $$s to do something but still no money for chairs.<br />Lots of catsno milk. Herding was a problemEnter Soo and Ray and WilliamFinally a semblance of a team that started to make things happen.<br />19. Then things started to happen<br />20. Massive Technical Challenges<br />)<br />Ran into every problem you can think of:<br />Hardware, Database, Software, Client management<br />Details:<br />Jumbo frames causing VMs to kernel panic<br />2 minute network separation between cloud controller &amp; VMs caused controller to decide to terminate instances<br />Prepare your container for the cloud it rains<br />Pieces of their really cloud ready.Indexes didnt fit in RAM (even with 96GB allocated to VMs)<br />21. Weekend Hack-a-Thon<br />Decided to spend the weekend hacking a new open source cloud controller framework. This became Nova<br />Some thoughts:Monolithic is bad each component should scale independently<br />APIs are good you shouldnt have to use web UI to configure<br />Simple things should be simple, hard things possible<br />The hard parts (hypervisor, storage system, networking) is done by others.Build a cloud the same way the way you build a scalable web application<br />Nova has been empowering NASA users for a year this May.<br />22. Launched USAspending.gov on5/21/2010<br />23. OpenStack History<br />2010<br />2005<br />March<br />May<br />June<br />July<br />Rackspace Cloud developed<br />Rackspace Decides to Open Source Cloud Software<br />NASA Open Sources Nebula Platform<br />OpenStack formed with contributions from Rackspace &amp; NASA<br />Inaugural Design Summit in Austin<br />24. Rackspace Called NASA<br />Rackspace:<br />Wow. Can we meet your team of 400 developers? <br />NASA:<br />Sure. We got 8 developers.And not all of them full time. <br />25. Why not a NASA-Driven Foundation?<br />Resources<br />Expertise<br />Focus<br />Not NASAs mission<br />26. NASA Nebulas contributions to OpenStack aligns with the Administrator's strategic goals<br />Facilitate the success of a viable commercial space industry to provide assured U.S. access to low Earth orbit for cargo and crew and acquire, mature, and infuse commercial capabilities across all NASA activities <br />Promote enhanced cooperation with international, industry, other U.S. government agency, and academic partners in the pursuit of our missions.<br />26<br />26<br />27. NASA Nebula + OpenStack supports the Agencys Goals:<br />Goal 6: Share NASA with the public, educators, and students to provide opportunities to participate in our mission, foster innovation and contribute to a strong National economy<br />28. NASA Nebula, Part 2<br />29. Developers from all over the world want to contribute code because they want to be part of the space exploration. <br />Overheard at the OpenStack Design Summit, My code could be part of NASA Nebula.This is as close to being astronaut I am ever going to get!<br />Overheard at Design Summit<br />30. IaaS Status as of the start of FY11<br /></p> <ul><li>Nebula is maturing from an Agency innovation project to a new OCIO service offering </li></ul> <p>31. In April 2010, the Alpha phase began with 20 users began 32. Even though weve been concentrating on ARC and GSFC,Beta closed with 240 IaaS users across 9 Centers, HQ,JPL, and NSSCthrough word of mouth 33. Nebula requires OCIO sponsorship to expand and become an institutionalized service for the entire AgencyGRC: 4<br />HQ: 8<br />GSFC: 104<br />MSFC: 2<br />ARC: 111<br />LaRC: 1<br />JSC: 4<br />JPL: 3<br />KSC: 1<br />NSSC: 2<br />SSC: 1<br />30<br />34. Our major challenge<br />35. How do we get here?<br />36. Requirements*<br />Current Options*<br />* Requirements and Options documented in over 30+ interviewswith Ames scientists as part 2009 NASA Workstation project.<br />37. Offer scientists services to address the gap<br />Desktop<br />TARGET COMPUTE PLATFORM<br />Server-based compute resources<br />Excellent example of how OCIO-sponsored innovation can be rapidly transformed into services that address Agency mission needs<br />High-end Compute<br />Vast Storage<br />High Speed Networking<br />Super Computer<br />34<br />38.
