ApacheCon NA 2010 - Developing Composite Apps for the Cloud with Apache Tuscany Presentation Transcript

  • 1. IBM Software Group SCA Reaches the Cloud Developing Composite Applications for the Cloud with Apache Tuscany Luciano Resende lresende@apache.org http://lresende.blogspot.com Jean-Sebastien Delfino jsdelfino@apache.org http://jsdelfino.blogspot.com 1 http://tuscany.apache.org
  • 2. IBM Software Group Agenda  Cloud Computing – Goals and Challenges  SCA – Goals and Overview  SCA – Typical Scenarios  Apache Tuscany  Tuscany Demo – Rewiring Components in the Cloud  Apache Nuvem  Nuvem Demo – Cloud friendly Components  Your Wish list?  Getting Involved 2 http://tuscany.apache.org
  • 3. IBM Software Group Cloud Computing 3 http://tuscany.apache.org
  • 4. IBM Software Group Cloud Computing – Some Goals  Up and running in seconds  Cheap  Scale up and down  Agile, reconfigure applications as business evolves 4 http://tuscany.apache.org
  • 5. IBM Software Group Cloud Computing – Not so easy?  Different platforms and APIs (even languages) to learn... does my business logic need to know?  Am I getting OS images on demand? Infrastructure? an application platform?  Changing pricing models?  How do I integrate hybrid clouds, on premise + public cloud?  How do the various parts of my app communicate? Which protocols am I using?  How do I assemble / integrate them?  How do I configure the QOS I need?  How do I automate deployment?  Can I move some parts from one cloud to another? 5 http://tuscany.apache.org
  • 6. IBM Software Group What is SCA ? 6 http://tuscany.apache.org
  • 7. IBM Software Group SCA - Goals  Abstract out technical APIs, protocols, QOS  Allow me to focus on my business logic  Give me a structure for componentizing my app  Help me assemble, wire, rewire, move parts around  OASIS Standard (in progress)  Open Source implementations  Apache Tuscany  Fabric3  a few others  Product implementations  Initial target: SOA, Web Services, multi-language apps, application integration 7 http://tuscany.apache.org
  • 8. IBM Software Group Can SCA components help you in the cloud?  We've been using different clouds in our Apache Tuscany work and are starting to realize that SCA components can help there too!  Components that easily communicate over a network  Components that shield you from different infrastructures  A way to describe your app and how it's assembled / wired  and can be distributed in a cloud or multiple clouds  Move components around clouds and rewire your app 8 http://tuscany.apache.org

  • 19. IBM Software Group Apache Tuscany 19 http://tuscany.apache.org
  • 20. IBM Software Group Apache Tuscany  Lightweight SCA runtimes  Leverage and integrate with the Apache platform  Active Open-Source community, started in 2005  “Release early release often”, many releases  Two release streams, 1.x (stable), 2.x (trunk)  Working on OASIS SCA compliance  Innovations beyond the SCA spec (JSON, REST, ATOM, Comet etc)  SCA Java runtime, standalone or on Google AppEngine / Java, supports Java, scripting, BPEL, Spring components, and many protocol bindings  SCA Python runtime on Google AppEngine / Python  SCA Native, supports C++ and Python components 20 http://tuscany.apache.org
  • 21. IBM Software Group Tuscany Demo – SCA Component Rewiring  SCA Java Application on EC2  Push one component out to Google AppEngine / Java  Rewrite it in Python and move it Google AppEngine / Python  Move it to a native SCA runtime on EC2  Easy runtime reconfiguration as you rewire the app  You've got choices, and can be agile! 21 http://tuscany.apache.org
  • 22. IBM Software Group Tuscany Demo – SCA Component Wiring Configuration Repository Fruit Catalog ((Native)) store Tuscany Runtime Currency Shell Converter Fruit Catalog currencyCode=USD ((Python)) Catalog jsonrpc Fruit Catalog (Java) 22 http://tuscany.apache.org
  • 23. IBM Software Group Apache Nuvem Components for the Cloud 23 http://tuscany.apache.org
  • 24. IBM Software Group Apache Nuvem - Overview  New project in the Apache incubator  Initial code contribution from Apache Tuscany  A few technical components already there  Running on Google AppEngine, today's demo also on EC2  Project is just starting so there's a lot of room for innovation! 24 http://tuscany.apache.org
  • 25. IBM Software Group Nuvem, REST, and Cloud friendly Components  With REST, components get a simple GET/POST/PUT/DELETE interface  More importantly it's a fixed interface  Making components easier to assemble and compose  Like Lego blocks!  Web apps are starting to favor a protocol short list  HTTP verbs with some format variations (XML, ATOM, RSS, JSON)  That helps too!  What if you had a palette of Cloud friendly components?  Accessible through a simple REST interface  To help simplify your apps and enable them to work on different clouds? 25 http://tuscany.apache.org
  • 26. IBM Software Group Nuvem Demo – Technical Components  SCA Java runtime on Google AppEngine / Java  Using different implementations of a simple datastore component  First using a HashMap  Second using Google's Memcached 26 http://tuscany.apache.org
  • 27. IBM Software Group Nuvem Demo – Technical Components store Currency Converter User currencyCode=USD Vegetables Catalog Catalog jsonrpc MapDocument Service ShoppingCart Manager MapDocument Service 27 http://tuscany.apache.org
  • 28. IBM Software Group Nuvem Components – Wish list  Simple data store cache  Hierarchical cache, which can delegate to another cache  Invocation cache, which caches responses to requests  Key/value datastore  Simple (S)QL datastore  Datastore that understands master/slave replication and sharding  XMPP chat  Message queue  Oauth 1.0/2.0 + OpenID  User profile 28 http://tuscany.apache.org
