6. Undesirable IT Development

7. Desirable IT Development IT developers— • Continue to create large / complicated core applications, but with associated Services. • Produce and expose Servicesthat enable access to data and functionality important to IT consumers. IT consumers— • Envision interesting applications and instead of producing a laundry list of requirements, they develop prototypes and applications using simple tools to aggregate and consume Services.

17. Abstraction Facilitates Innovation • When you expose Web Services you are providing an API • It should be intuitive • It should be safe • It should be documented • It should be supported • It should be exposed through “the registry” • There may be hierarchies of Services • Data Services • Core application Services • AIM, PeopleSoft, etc. • Aggregated Services • GMU • Not all Services may be exposed to everyone • No Service Silos • Services must be architected from the top down • Not necessary to have management and provider services • Performance
