  1. Unveiling CloudTaoPaaS Platform Ruan Zhimin ruanzhimin@gmail.com 2010/09

  2. Our Viewpoint • Next generation applications will be running in cloud side. • PaaS is the next generation Application Server in the cloud. • Next generation SaaS applications are running on Paas Platform. PaaS is the key to realize personalize requirement. • Leveraging existing applications on PaaS Platform

  3. 应用部署的变迁

  4. Model to Business Process 1st SaaS 2nd SaaS PaaS Business Vanilla ERP Bespoken with 4GL Software as a Service IT Customize logic to project Assemble-to-Order Make-to-Stock Mass Customization Engineer-to-Order Billions $ Millions $ xx-K $ x-K $ Engineer logic to Database 应用开发的变迁 Generic Components Business Specific Components culture of re-use one-off culture

  5. Key Learning and Enabling Technology • Stateless connection is the key to scale. Service-oriented UI + service is suitable for all client. • Google: Google App Engine is just to process http request. Window Azure’s web/work role concept. • Jetty: high performance embedded http server/servlet container. • Multitenant at multiple level

  6. Cloudset and Cloud First Level Multitenant Cloudset Master Cloudset Second Level Multitenant Cloudset cloud cloud cloud cloud cloud Dedicated resource can be assigned to a cloudset. Dedicated resource can be also assigned to a cloud inside an cloudset Resource Pool

  7. Cloud and Service Node • A Cloud contains a set of service nodes • A service node can handling a set of targeting http request. Cloud Third Level Multitenant Service Node Service Node Service Node Service Node

  8. Service Node and Service Processor Service Node Processor 1 • A service is packed into a war which can be self-started in an embedded jetty. • A service Node contains several service processors each refer to a running jetty instance. Forth Level Multitenant (Embed Jetty instance listening on: 192.168.64.101: 8083) Processor 2 (Embed Jetty instance listening on: 192.168.64.102： 8084) Processor3 (Embed Jetty instance listening on: 192.168.64.102： 8085)
