Establishing an SOA Focused Enterprise Architecture

Asanka AbeysingheWSO2, Inc

Vice President, Solutions Architecture

Goal of the day

- Service Oriented Architecture- Enterprise Architecture- EA challenges - How SOA helps to address EA challenges - Common business architecture pattern - Lab exercise (Solution building)- Q&A

Service Oriented Architecture

“Architecture paradigm to build highly loosely coupled distributed systems”

Service Oriented Architecture cont.

“Nothing NEW, architecture style to fix the broken architectures”

Pre-services Era

SOA at Kindergarten

SOA cont.

SOA today – Design Time

SOA today – Run Time

API-centric SOA

“API Management, the missing link for SOA success.”- Sanjiva Weerawarana

API-centric SOA cont.

API Façade

Enterprise Architecture

“Manage the complexity of the IT environment and applies principles and techniques to reduce the complexity,improve efficiencies, and reduce capital and operational

expenditure.”

EA Challenges

- Enterprise Architecture has changed- Less visibility to projects

- Difficult to find - Availability - Ownership

- Development cycles:- From 18 to 6 months to 3 months

- Change management - Real standards

- Technical (REST, SOAP, protobuf)- Business (ACORD, HL7, FIX, FAST)

- Integration is key (extend to connected business)- Companies without integration are falling behind- Heterogeneous systems

Code vs Configuration

“Professional coders make 100-150 errors per thousand

lines of code .”

Configuration Driven

Recap

SOA principles EA challenges

Loosely coupled services Loosely coupled development efforts (e.g. accommodate some schedule asynchrony)

Flexibility under changing business conditions

Flexibility under changing requirements

Fast time to market of new business capabilities

Short release cycle with incremental utility

Heterogeneous environments Choose the best tool for each job

Good governance practices and tools Community-centric tools:• Versioned repository• Peer visibility and review• Rich communication channels• Issue and status tracking• Automated build/test
