6. Architecture objectives end user perspective Performance –>1s response time Usability –a user should with ease learn to operate, prepare inputs for, and interpret outputs Availability –high availability - 24x7

7. Architecture objectives customer perspective Security –the M-CAST system should have the ability to manage, protect, and distribute sensitive information –copyrights Interoperability –the M-CAST system should have the ability to use the information that has been exchanged with various systems (resources) Scalability –the M-CAST architecture should be modified with ease to fit the performance and volume requirements

8. Architecture objectives producer perspective Time span –the architecture and technology should be in use in 2007 Portability –the M-CAST system should be transferred with ease from one hardware or software environment to another Flexibility –the M-CAST architecture should be modified with ease for use in applications or environments other than those for which it was specifically designed

9. Architectural decision SOA Service-oriented architecture is an approach to loosely coupled, protocol independent, standards-based distributed computing where software resources available on the network are considered as services.
