This document outlines an agenda for embarking on a SOA/API journey. It discusses why SOA/API is important and how to run a successful SOA program through governance, framework, and community. Real-world challenges with SOA like versioning, time to market, and scaling are also covered. The document warns against "pretending SOA" and advocates for true SOA using orchestration in addition to transport.

8. How to run successful SOA Program?
•3 things

9. 1. Governance*
•Standards defining Body
•Protocol Specifications –Interoperability, Fault Handling, Schemas…
•Security Specifications
•SLA, OLA
•Domain Ownership
•Competing services willevolve over time
•Discovery Model
*Has potential to become bureaucratic.
Should be a facilitator.
Governance

Why not Census bureau xml?

10. 2. Framework*
•Developer Productivity -Each Organizational unit shouldn’t solve same problem
•Drive Consistency –Successful Patterns, Best Practices
•Team
•Experts from critical applications in Enterprise
•Meritocracy
•Internal open source model
* Don’t try to solve ‘World’s Hunger Problem’
Support Model
Framework

11. 3. Community
•Periodic Touch points
•Updates –Governance, Framework
•Internal Social Network, Wiki space, Mailing Group
•Forums
•Train Developers
•Invite Industry Speakers/Innovators
•Share what’s going on with other teams
Community

12. Effective Communication
Governance
Community
Framework
SOA Excellence

13. Real-world challenges
Versioning
•Cost to support old
Versions vs Cost to migrate
Time to Market
•SODA vs Monolithic
Deployment
Scaling
•Stateless
•Public Cloud vs
Private Cloud
