  1. Play with Cloud Foundry An Open PaaS Shi, Tao May 11, 2012

  2. Agenda • Overview • Development Guide • Deployment Guide • Resource • Q&A

  3. Cloud Foundry Overview • What’s Cloud Foundry? • Languages/Frameworks • Inner Service • Logic View • Architecture • Disadvantages

  4. Cloud Computing System

  5. What’s Cloud Foundry? An open platform-as-a-service (PaaS). The system supports multiple frameworks, multiple application infrastructure services and deployment to multiple clouds.

  6. Languages/Frameworks/Service • Multi-Language • Ruby, Java, Scala, Node.js, Erlang, Python, PHP.. • Multi-Framework • Rails, Sinatra, Spring, Grails, Express, Lift • Multi-Services • MySQL, Postgres, MongoDB, Redis, RabbitMQ • Multi-Cloud, Multi-IaaS • Public Cloud, MicroCloud, Private Cloud

  7. Logic View vmc client STS plugin browser (user app access) Router Health Manager Cloud Controller user apps user apps DEA: execution environment Services: core, ecosystem, etc. • Infrastructure

  8. Architecture

  9. Disadvantages • Limited Services • Limited File Generate/Access • Charge Public Cloud • No Infrastructure in China • Beta

  10. Agenda • Overview • Development Guide • Deployment Guide • Resource • Q&A

  11. Prepare • Register • Install Ruby and RubyGems • Install VMC (VMware Cloud Client) • Install STS (with Cloud Foundry Plugin)

  12. Spring to Cloud Foundry • Auto Reconfiguration • Cloud Namespace • Spring 3.1 Profiles

  13. Auto Reconfiguration • Two modifications • Additional Jar • Update Web.xml • BeanFactoryPostProcessor Examines the application context before creating beans • Swaps existing beans of matching types

  14. Auto Reconfiguration

  15. Cloud App Setup • Maven • Spring Application-Context

  16. Cloud Namespace • Support Data Source • Other Support

  17. Spring 3.1 Profiles • V3.1 adds new support for environments • Stand-alone Containers

  20. Agenda • Overview • Development Guide • Deployment Guide • Resource • Q&A

  21. Deployment Guide • Deploy App • Update App • Binding Service to App • Start/Stop App • Scale App

  22. Deploy App • vmc login • vmc target • vmc push • vmc update • vmc create-service • vmc bind-service Via VMC Via STS

  23. Access Service • TCPoverHTTPtunnel • Localclient • Remoteserver • gem install caldecott • vmc tunnel your-service • Mongodb/mysql command Caldecott

  27. Agenda • Overview • Development Guide • Deployment Guide • Resource • Q&A

  28. Things to Forget • First normal form • Waterfall model • Single server deployment • Single language skill • Build everything from scratch • Build custom infrastructure

  29. Things to Learn • Agile, API Design • UI Design, Javacript, HTML5, CSS3 • A/B Testing • Open Source, Open Standards • Architecture, Distributed Computing • Cloud Platforms and APIs • Multiple types of languages (imperative, object, functional, logic) • Ability to encapsulate domain knowledge in a DSL • Build on the shoulders of giants: reuse, rest APIs • Pick your battles, choose what you need to build yourself to add value • Learn to live in a box (embrace platform limitations) to think outside the box • Use an App Store for distribution
