This document provides an introduction to service oriented architecture (SOA). It defines SOA as an architectural model that enhances efficiency, agility and productivity through a collection of loosely coupled services and connections. The document outlines the benefits of SOA from both technology and business perspectives, such as improved integration, flexibility and global sourcing. Challenges of adopting SOA include the early adoption of supporting technologies, organizational changes and complex program management. The document concludes by stating that modern SOA is based on web services and lists some programming languages used to implement SOA.

14. Broadly SOA can be classified into two terms : SERVICES CONNECTIONS Nexgen Institute of Business & Technology

15. What is a Service ? A service is a function that is well-defined, self-contained, and does not depend on the context or state of other services. Nexgen Institute of Business & Technology

16. What is a Connection ? A link that connecting these self-contained distributed services with each other . Service Consumer Service Provider Service Response Service Request Nexgen Institute of Business & Technology

22. Challenges of SOA Early adoption and evolution of supporting technology . Organization change in necessary since SOA crosses system boundaries. Program management is often complex due to project interdependencies and new technology risks. The change impact to the infrastructure and users. Quality Assurance is difficult.
