What is Service Oriented Architecture (SOA) ?

History of Distributed ComputingHistory of Distributed Computing

Issues with Existing Models

• Proprietary protocols• Interoperability• Platform lock-in• Inflexible

What is SOA ?

• Evolution of distributed computing• Application functions are modularized and

presented as services• IT architecture for synchronous and

asynchronous applications• Services are loosely coupled

• Service interface is independent of the implementation

Why SOA ? - The Reality of Modern Business

• Geographic, Departmental Evolution

• Mergers & Acquisitions (M & A)

• Compliance issues• Difficult to Answer Simple

Questions• Costly to Operate• Inflexible

Difficult to achieve benefits of an Information-Driven Enterprise

Benefits of SOA

• Better reuse• Build new client functionality on top of existing

Business Services

• Well defined interfaces• Make changes without affecting clients

• Easier to maintain• Changes/Versions are not all-or-nothing

• Better flexibility
