  1. 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 />
  2. 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. 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 NASA’s Nebula, the space agency’s new data powerhouse, which provides on-demand computing power for NASA researchers. <br /><br />“The world will end if we don’t 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 NASA’s real compute issues”<br />New NASA Center CIO<br />“Because we need more developers”<br />Well known cloud architect<br />
  4. 4. Tell you the unofficial Story of how NASA Nebula started…..from my perspective. I was there for most of it. I’ve 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. 5. NASA Nebula, Part 1<br />
  6. 6. 1000s of other NASA websites<br />"A long time ago in a US Agency far, far away.... (well, DC is far)"<br /><br />Photo Credit: www.starwars,com<br />Photo Credit: www.starwars,com<br />
  7. 7. Why wouldn’t they join<br /><br />Perception:<br />Control<br />Issues with CMS<br />Flexibility<br />Cost <br />Photo Credit: www.starwars,com<br />
  8. 8. There’s 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 /> was born<br />
  9. 9.<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. 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. 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<br />Chris didn’t pay for lunch.<br /> Photo Credit:<br />
  12. 12. Problem<br />Us: “Thanks! We need funding..”<br />Everyone: “Great Idea!”<br />
  13. 13.
  14. 14. Why?<br />FY09: <br />Line item for cloud?<br />FY06: <br />Plan FY09 Budget<br />How do we fund IT innovation? <br />
  15. 15. At the same time, White House “cloud first” initiative was gaining traction<br />Federal CIO, VivekKundra evangelized 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.<br />
  16. 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. 17. We didn’t 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(“He’s got cloud, and he knows how to use them..”)<br />I bought cases of Red Bull to cover up the fact I didn’t have money for chairs.<br />But ARC is creative….. <br />
  18. 18.<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 cats……no milk…. Herding was a problem…… Enter Soo and Ray and William……Finally a semblance of a team that started to make things happen.<br />
  19. 19. Then things started to happen<br />
  20. 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 & 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 didn’t fit in RAM (even with 96GB allocated to VMs)<br />
  21. 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 shouldn’t 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. 22. Launched on5/21/2010<br />
  23. 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 & NASA<br />Inaugural Design Summit in Austin<br />
  24. 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. 25. Why not a NASA-Driven Foundation?<br />Resources<br />Expertise<br />Focus<br />Not NASA’s mission<br />
  26. 26. NASA Nebula’s 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. 27. NASA Nebula + OpenStack supports the Agency’s 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. 28. NASA Nebula, Part 2<br />
  29. 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. 30. IaaS Status as of the start of FY11<br /><ul><li>Nebula is maturing from an Agency innovation project to a new OCIO service offering
  31. 31. In April 2010, the Alpha phase began with 20 users began
  32. 32. Even though we’ve been concentrating on ARC and GSFC, Beta closed with 240 IaaS users across 9 Centers, HQ, JPL, and NSSC through word of mouth
  33. 33. Nebula requires OCIO sponsorship to expand and become an institutionalized service for the entire Agency</li></ul>GRC: 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 />

  53. 53. 100 CPU hrsper galaxy
  54. 54. We upped instance quota to get started</li></ul>Nebula Project #2: Some sky areas require huge RAM-based processing.<br /><ul><li>We set up an 80 GB RAM instance
  55. 55. Finished first phase on Nebula in two days. </li></li></ul><li>WISE Region Processing<br />
  56. 56. WISE Cloud Processing<br />
  57. 57. WISE Galaxy Processing<br />
  58. 58. Possible Cloud Applications<br />Hundreds of galaxies can be hi-res processed to provide higher angular resolution images for better studies of star formation, galactic structure, etc. <br />Thousands of galaxies could be hi-res processed to resolve & measure source sizes, etc.<br />Hundreds of thousands of galaxies can be hi-res processed to differentiate point-like (active galactic nucleus or nuclear star formation) from distributed (merger or spiral galaxy) emission.<br />Several large regions nearby can be surveyed for distributed star formation in our galaxy. <br />A few large regions can be processed to tremendous depth. <br />The whole sky can be hi-res processed.<br />“conducted calculations that could not be done on our project's large server farm.  ”<br />

  61. 61. NASA Nebula, Part 3<br />
  62. 62. Nebula will continue to be part of the open source community<br />Nebula is being incorporated as an option in the overarching computational services for the agency. And yes….we are looking at commercial clouds too. Operational management is being implemented.<br />Nebula continues to be supported by the Agency and the Agency is working to define strategies for cloud use.<br />The Agency is defining its current use cases for cloud to ensure adoption.<br />ARC is currently developing a cloud migration strategy for business and operational organizations. Are you cloud ready? <br />ARC is beginning to incorporate cloud into their mission proposal process.<br />Security in the cloud continues to be a driver. Pushing towards moderate and ITAR usage.<br />What NASA is doing………<br />
  63. 63. Continue Collaboration<br />Nebula<br /><ul><li>Hundreds of contributions of large and small companies have improved OpenStack since release
  64. 64. NASA has benefited from OpenStack contributions integrating ideas and patches into Nebula after appropriate review.</li></li></ul><li>Key OpenStack Community Contributions powering NASA Nebula<br /><ul><li>Virtual Firewall Service: Implemented by Ubuntu developer
  65. 65. Windows Support: Disk support added by San Francisco startup FathomDB
  66. 66. IPv6: Developed by Japanese telecom NTT</li></li></ul><li>OpenStack & NASA<br />How NASA can ensure OpenStack works for NASA<br /><ul><li>Initially very active participant, ensuring NASA’s requirements are in the DNA of OpenStack
  67. 67. As OpenStack matures NASA moves from contributor to user. “as they stand up as we stand down”</li></li></ul><li>Regardless of the road taken to get here….. <br />NASA does support and funds Nebula …At all levels. From the administrator suite to the stock room. A group of very innovative people working together to make it happen….technical, business, and political.<br />There are lots of stories of attribution..… but the truth is….it was done here with all of you……. So thanks to all the contributors that are here. <br />What NASA has done……<br />
  68. 68. Open source means moving faster and smarter<br />Moving inertia takes great strength. <br />People aren’t wrong in the way they do things. It still works for them. They just have to be shown why another way is better for the future.<br />Messaging and direction should always be clear. The why needs to be solid. The how agreed upon. And the message accurate.<br />Passion for the mission outweighs the paycheck. Yes some of us really do work for NASA because it is NASA.<br />Never ask hippy developers to show up to an 8 a.m. meeting.<br />What have I learned…..<br />
