  1. Promoting Open Source Software Through Cloud Deployment: Library à la Carte, Heroku, and OSU Michael B. Klein Digital Applications Librarian michael.klein@oregonstate.eduMargaret Mellinger Engineering Librarian margaret.mellinger@oregonstate.edu

  2. About Library à la Carte • What is Library à la Carte? • Distribution & Adoption • Cloud Deployment • Why the Cloud? • Hosting Options • Challenges and Compromises • Pilot Project • Evaluation • Future Directions Presentation Overview

  3. Custom content management system • Course assignment pages, subject guides, portal pages and tutorials • Pages built around reusable modules • Text, images, media widgets, links, feeds • Free & open-source  • Download, install, and start using  • Customizable and extensible What is Library à la Carte?

  4. 5 major releases since 2007 • Scores of demo accounts requested • Downloaded hundreds of times • 20+ known installations Distribution

  5. Lack of in-house technical expertise • Installing Ruby and dependencies • Setting permissions • Webserver configuration • Database administration • Running scripts from the command line • Hand-editing configuration files • Installing upgrades/applying patches • Diagnosing and reporting problems • Unwillingness or inability to devote technical or human resources Barriers to Adoption

  6. Pre-installed • Lower the barrier for adoption • Dedicated • Provide libraries with their own installations where they can do real work • Portable • Entire installation can be moved from the cloud to a local install or vice versa • Elastic • Storage space and resources can be allocated on the fly Why the Cloud?

  7. Amazon Web Services • Elastic Compute Cloud (EC2) • Controllable via console or API • Infrastructure as a Service (“Bare Metal”) • Small instance: 10¢/hr. = $72/mo. = $864/yr. • Boot volume and storage costs are extra • Refactoring required to take advantage of elasticity • Additional refactoring required to compensate for ephemeral server instances Hosting Options

  8. JumpBox • Portable virtual machine • Still “Bare Metal,” but host-agnostic • Requires acceptance by JumpBox team • Installation, maintenance, and upgrades may require vendor action • Still need to provide hardware or pay EC2 costs Hosting Options

  9. Eucalyptus • Open Source cloud platform • Based on Amazon cloud model and API • Software is free; infrastructure is not • We would have to provide hardware and additional support Hosting Options

  10. Heroku • Platform as a Service • Dedicated Ruby/Rack/Rails platform • Git-based deployment • Ruby API • Automatic, easy scaling and load balancing • Predictable costs • Over 2 dozen available add-ons • Smallest instance: FREE Hosting Options

  11. Hosting Options

  12. No server-side file storage • Requires another solution such as Amazon S3 • No dedicated configuration files • Library à La Carte was written for MySQL • Heroku uses PostgreSQL • Developers aren’t necessarily thinking of the cloud when adding new features Challenges and Compromises

  13. Deployment Application

  16. Deployment Application

  17. Single insitutional partner • Deployed in January 2010 • Goals: • Administer and monitor installation • Track usage, database size, bandwidth • Develop cost model based on likely usage scenarios • Gather feedback from partner Pilot Project

  18. Initial evaluation June 2010 • Overall experience very positive • Need to document differences between standalone and cloud-based app • Users used to page creation had trouble adjusting to content management workflow Pilot Project – Librarian Evaluation

  19. Faculty and students consider Library à la Carte to be a valuable resource • Goal: “Collect all the necessary sources students need to use in their clinical year.” • Students “thrilled with having one starting place.” • Already receiving requests for additional content. Pilot Project – User Evaluation

  20. Administration & Maintenance • 2 software updates in 6 months • 30 minutes to install, including code review • Marginal time cost of updating additional hosted sites would be 2-3 minutes • Support • Installation/configuration support eliminated • Some hand-holding still required Pilot Project – OSU Evaluation

  21. Revisit hosting model • Is Heroku working for us? • Would Amazon EC2 make more sense? • Determine costs based on size and use • Consider other partnerships • Hand hosting off to consortium? Future Directions
