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)
