Business need of IT systems to get integrated. Why legacy systems are feeling modern technologies like SOA can help them to keep alive by providing the integration solution.

2. Agenda
 Why Enterprise Integration ?
 The Problem
 The Solution
 SOA, SOA Principles and SCA
 Oracle’s Solution
 Oracle SOA Suite
 SOA Suite Architecture
 SOA Suite components

3. Why Enterprise Integration?

4. The Problem
Universal Bank Limited
1. Time to develop comm. layer
2. Business IT Gap
3. P2P maintenance?
4. 2^(n-1) connections, n is no of
components
5. Tight coupling
6. Expensive
7. Too much change for simple
extension

5. The Solution
Universal Bank Limited
1. Common middle layer
2. Service registry
3. Wrap the Code-XML
4. N connections
5. Loose coupling
6. Less expensive
7. Change only to Wrapper-XML

6. SOA, SOA Principles & SCA

7. SOA (Service Oriented Architecture)
A service-oriented architecture (SOA) is an architectural style of building
business applications using services that acts as black boxes, which
can be composed to each other, thus achieving a specific business
functionality.
Set of Standards- business agility, respond quickly to change, easily
maintainable, extendable, cost-effective(utilize existing resources),
reducing IT-Business Gap.
Not a technology, specification or a framework!

8. SOA Principles
1. Service Contract – Communication agreement b/w interacting services
2. Service Abstraction –Internal details hidden to external world
3. Service Discoverability – Services should be discoverable in a standard way
4. Service Autonomy – Complete control over its functionality
5. Service Loose Coupling –Dependency b/w services shouldn’t go beyond
knowing the target service
6. Service Reusability – Easily reusable
7. Service Composition – Services should be effective composition participants,
regardless of size and complexity of composition
8. Service Statelessness – State of an instance shouldn’t be preserved beyond a
single request

9. Service Component Architecture
SCA is a Unifying framework for standardizing and simplifying the
development, deployment and management of atomic service
components.
SCA provides a model for building applications that leverage SOA
principles.
It is like a platform on which you develop your SOA applications in a
more standard, easier and flexible manner

10. Oracle’s Implementation to SCA
Tool to build SOA Based Applications

11. Oracle SOA Suite
 Oracle SOA Suite enables system developers to set up and
manage services and to orchestrate them into composite
applications and business processes.
 With Oracle SOA Suite's hot-pluggable components,
organizations can easily extend and evolve their
architectures instead of replacing existing investments.
