SOA/API World – Tomorrow** - I am after all Ram Lakshmanan. Forgive me as well

 ”640K ought to be enough for anyone. – Bill Gates, 1981”

Driving forces, that will shape future

1. Industry trend2. End User3. Business Operator4. Partner/Developer

#1 – Industry TrendExplosion of devices

2018 – 12.1 billion mobile devices 2020 – 26 billion IOT devices

Smaller, Faster APIs

Answer: Binary Protocols

• Google Protocol Buffers, Binary XML, Hessian/Burlap…

• What goes around comes around

Smaller Payloads Faster APIs

SOA will do more

SODA - Micro Services *

* - Too many SODA/Micro Services, can lead to maintenance/ deployment nightmare

Monolithic Deployment SODA

SOA Governance - Prominence

Solution• Enterprises will start to investin SOA Governance.

Problems• Competing Services between organizations in enterprise.• Interoperability between services• Lacks of standards

#2 – End UserGot used to best of the best

SOA will start to think

• Broad cast vs Narrow cast

SOA

Same Itinerary, different prices

Customer-A 1050$Customer-B 1000$

More Analytics from SOA

If there is one place where all information flows - it’s SOA

• End user Data

• Channel/LOB Data

• Partner Data

• Internal SOR Data

• External SOR Data

Traffic volume will increase

• SPA (Scalability, Performance, Availability)

• Can talk about it for hours.

• Self-healing (Circuit Breaker Pattern)

#3 – Business OperatorIn several enterprises “Technology is a cost”

Elastic Cloud

• Traffic – High tides, Low tides in a day.• Under utilized compute resources

• Add compute power on demand. • Through APIs

Relaxed Schemas

Versioning - Expensive

• Provider: Cost to support old versions• Consumer: Cost to migrate

Relaxed Schemas

• Relaxed schemas, Loose typing

#4 – Partner/DeveloperMost Demanding guy

Multiple Interfaces

HessianBinary

Tooling

Documentation

• Auto-Generation• Collaborative/Interactive Environment

On-boarding

• Credential Generation• API Authorization

management• Discontinue

Security Standards will evolve

Authorization

With APIs, Data has started to flow everywhere

API Store

Discovery Model - Broken

• UDDI Broken• No significant alternative exist

API Store
