Congratulations! For embarking on this wonderful SOA/API journey
Agenda •A Story •Why SOA/API? •How to run Successful SOA Program? •Real-world Challenges •Warning -Pretending SOA Note:Not going to bore you. Only 15 slides. You are already on 3rdslide.
Few words about me Leisure Travel application - processes 60% of North America’s travel Financial applications used by 1 in 3 house holds in US Architected one of the world’s largest SOA Platform Built …
A story •Small Story: Once upon a time ….. •Moral: •Technology choice is critical •Vendor choice is critical even more ^
SOA/API World SOR-2 SOR-n SOR-5 SOR-3 SOR-4 SOR-6 SOR-1 Online App Mobile App Stores App Call Center App Other LOB Apps (100+) SOA <SOAP/> HTTP JDBC JMS HTTPS LDAP
SOR-2 SOR-n SOR-5 SOR-3 SOR-4 SOR-6 SOR-1 LOB -1 HTTP JDBC JMS HTTPS LDAP World before SOA LOB -2 LOB -n Expensive, Time consuming, inconsistent
How to run successful SOA Program? •3 things
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 <cbXml/> - Why not Census bureau xml?
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
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
Effective Communication Governance Community Framework SOA Excellence
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
Warning -Pretending SOA SOR-1 Problem trying to solve Seen in several Enterprises SOR-n LOB-1 LOB-n SOR- 1 SOR- n SOA LOB-n LOB-1 SOR- 1 SOR- n SOA LOB-n LOB-1 Pretending SOA. Just Transport Real SOA. Orchestration + Transport SOR Invocation Logic Orchestration Logic
