20 Reflections- many development supporting software involved Tools Business process modeler Service composition tool Verification and test tool Service deployment tool Monitoring tool Middleware Service container Composite service execution engine (workflow engine) Service bus 20

21 Problems The extra work for developers Install and configure various development tools Install and configure runtime supporting middleware Obtain and maintain underlying resources Machines Networks However they should focus on development. Dev. Service! 21

22 The crux of cloud computing Service IaaS: Infrastructure as a Service PaaS: Platform as a Service SaaS: Software as a Service Can we make use of cloud computing to save developers from the extra work? An online development environment A hosting platform An on-demand infrastructure service 22

23 Our goal Building a cloud platform for service oriented software development Instant development without installing tools Instant deployment without installing middleware Instant running without knowing the underlying resources 23

24 Moving towards a cloud platform Online application development Browser-based IDE Business process centric development Online sharing of software services Transparent deployment and running Similar to Google AppEngine, etc. 24
