2. Topic Coverage Introduction to cloud computing Challenges and Features iPlant Atmosphere iPlant Data Store Designing course work and training material using Atmosphere and Data Store Using Atmosphere + Data Store (hands on) Explore use of these resources on your own and ask questions !

3. Survey Results 12 responses I would like to use cloud based resources for: teaching (1) research (10) both (10) I have used cloud resources before: Yes (1) No (11) I have tuned the content to best of my ability to what participants have requested I promised not to use much jargon, please stop and ask questions ANY time

4. We have designed iPlant to be consistent with the pillars of CIF21 High Performance Computing Data and Data Analysis Virtual Organization Learning and Workforce The iPlant Collaborative Cyberinfrastructure Philosophy

5. Typical End Users Computational Users Teragrid XSEDE The iPlant Collaborative Cyberinfrastructure for the Plant Sciences

6. For a challenge as broad as “plant science,” focus on specific applications/tools is a moving target, and never enough. Most important to build a platform that can support diverse and constantly evolving needs. “Cyberinfrastructure” is, in fact, infrastructure. The platform can lift all the apps, not select winners and losers. “ The useful lifetime of our analysis toolchains is now 6 months” -Matthew Trunnel, Broad Institute The iPlant Collaborative Cyberinfrastructure for the Plant Sciences

7. The iPlant Collaborative Cyberinfrastructure for the Plant Sciences The iPlant CI is designed as infrastructure. This means it is a platform upon which other projects can build. Use of the iPlant infrastructure can take one of several forms: Storage Computation Hosting Web Services Scalability

8. The iPlant Collaborative Ways to access iPlant Atmosphere: For cloud infrastructure iPlant Data Storage: All data large and small The Discovery Environment: Integrated Web apps. MyPlant: Social Networking. DNASubway: Annotation and more Standalone Apps: TNRS, TreeViewer, PhytoBisque, etc The API: For programmers embedding iPlant CI capabilities Command line for experts (through TeraGrid/XSEDE)

9. Cloud Computing Not a singular technology component Not a black box or alien technology Not a “elixir of scalability”, “panacea for Big Data” etc. It cannot keep growing and scaling without planning (and architecting your application) Unfortunate victim of marketing hype Further complicated by use of jargon, TLA, private cloud, community cloud, hybrid cloud …

10. What is cloud computing ? http://geekandpoke.typepad.com/geekandpoke/2009/03/let-the-clouds-make-your-life-easier.html

11. Cloud Computing Amazingly flexible technology It’s a platform that comprise of many uniquely flexible components (more later) Allows us to create “purpose built appliances” Allows us to finally “script our infrastructure” Allows mixing and matching of components that you need to do your science Opens up many new avenues and approaches for teaching topics that require complex (pre configured) software tools and data

12. Often overheard I do my analysis using the “cloud” It’s the close equivalent of saying: I do my research using “science”

13. 13 Cloud Computing Zen Don’t get frustrated… –This is cutting (bleeding) edge technology –There will be plenty of WTF#$@ moments Be patient… –Instructions/infrastructure keep changing (s/w version) Be flexible… –There will be unanticipated issues along the way Be constructive… –Use wiki, forums and share knowledge – Make everyone’s experience better Be creative… –There is more than one way to do it (TIM-TOWTDI)

14. iPlant URL’s you should know Wiki.iplantcollaborative.org Forum.iplantcollaborative.org ask.iplantcollaborative.org www.iplantcollaborative.org

15. Impromptu survey How many of you use command line How many of you are windows, mac, linux users ? How many of you use HPC ? (or know what HPC is) What campus resources do you use to teach computing based workshops/courses

16. Atmosphere: motivation Standalone GUI-based applications are frequently required for analysis GUI apps not easily to transform into web apps Need to handle complex software dependencies (e.g specific bioperl version and R modules) Users needing full control of their software stack (occasional sudo access) Need to share desktop/applications for collaborative analysis (remote collaborators) Availability of Next Gen map-reduce based algorithms (currently we have limited support)

17. 17 SaaS: Software as a Service (e.g. Clustering/Assembly is a service) IaaS : Infrastructure as a Service (get computer time with a credit card and with a Web interface like EC2) PaaS : Platform as a Service IaaS plus core software capabilities on which you build SaaS (e.g. Hadoop/MapReduce is a Platform) Cyberinfrastructure Is “ Research as a Service ” http://salsahpc.indiana.edu As a Service models More Pain More Flexibility Productivity

18. But where do I start ? Not very helpful searching for “cloud computing ” related terms (as you will most likely get bombarded by commercials and advertisements in the first few hits !) NIST: National Institute of Standards and Technology Cloud Computing Synopsis and Recommendations (Special Publication 800-146 : May 2012) http://www.nist.gov/customcf/get_pdf.cfm?pub_id=911075

19. What it is

20. Challenges of existing platforms Amazon Web Services (AWS) http://aws.amazon.com/ http://aws.amazon.com/ Flexible and scalable High level of expertise required for configurations Fairly challenging for biologists to master all steps Limited lifecycle management (cost, time)

21. Steps to get started !

22. What is Atmosphere ? Self-service cloud infrastructure Designed to make underlying cloud infrastructure easy to use by novice user Built on open source Eucalyptus (OpenStack) Fully integrated into iPlant authentication and storage and HPC capabilities Enables users to build custom images/appliances and share with community Cross-platform desktop access to GUI applications in the cloud (using VNC) Provide easy web based access to resources

23. Who is this tutorial designed for ? Users wanting to launch configured images in atmosphere (like app store) Developers for application distribution Prototyping/Testing new software/modules Tailored software training setups (custom workshops/laboratory courses etc) Extend compute capabilities of existing applications i.e. utilize iPlant API

24. API-compatible implementation of Amazon EC2/S3 interfaces Virtualize the execution environment for applications and services Up to 12 core / 48 GB instances Access to Cloud Storage + EBS Run servers, CloudBurst desktop use cases. Big data and the desktop are co- local again! >60 hosted applications in Atmosphere today, including users from USDA, Forest Service, database providers, etc. (30 more for postdocs and grad students for training classes) The iPlant Collaborative Project Atmosphere™: Custom Cloud Computing

29. Asian Wild Rice Distribution The Research Genetic studies documented geographic subdivision of Asian wild rice ( Oryza rufipogon ), the progenitor of cultivated Asian rice. – Cause unknown. Use species distribution modeling (SDM) to examine environmental factors associated with the spatial and temporal distribution of O. rufipogon. Compare estimated distribution during Last Glacial Maximum (LGM) to genetic data. Problem Analysis requires large datasets Results Present distribution of O. rufipogon (Fig. A). Projected paleodistribution at LGM was separated into disconnected east and west ranges (Fig. B). – Consistent with current geographic pattern of genetic variation, with two genetic groups that intergrade (Fig. D). Annual precipitation contributes most to SDM estimates. SDM projections for year 2080 indicate an increasing probability of presence and range expansion (Fig. C). – Indicates global warming is less threat to this endangered species than other human-mediated factors. Scalable science 325 records of O. rufipogon sample locations from two sources. iPlant enabled Huang and Schaal to successfully pursue this research. (A) present, (B) Last Glacial Maximum, (C) Future 2080, (D) Genetic variation. iPlant Workshop at BSA, July 2011 Pu Huang (Washington U.) attended. Learned about Atmosphere, iPlant’s cloud computing platform. P Huang and B.A. Schaal, Am. J. Botany 99(11). 2012.
