3 24 February 2016 Introduction to SOA

24 February Procedural Approach Object Oriented Approach Component Based Approach Service Oriented Approach Evolution of SOA

24 February Client-Server Architecture Three-Tier Architecture Distributed Internet Architecture Service Oriented Architecture Evolution of SOA

24 February SOA is NOT Web Service (only) SOA is NOT another marketing term SOA is NOT a Product SOA is NOT Off the Self Solution SOA is NOT One-Time process SOA is NOT a Silver Bullet SOA is NOT Easy What is NOT SOA?

24 February SOA is NOT Web Service (only) : SOA is an architecture SOA is NOT another marketing term : SOA is Real SOA is NOT a Product : SOA is a Process SOA is NOT Off the Self Solution : SOA is Building Block SOA is NOT One-Time process : SOA is an Evolution SOA is NOT a Silver Bullet : SOA is Maturing SOA is NOT Easy : SOA is Achievable What is SOA?

24 February SOA stands for Service Oriented Architecture. Its an architecture The functionality is exposed as Services It follows principles of service orientation The services are independent, loosely coupled, open standards based and exposes a definite public interface Services communicate through messages TCS Definition TCS defines SOA as an architectural style and a platform-agnostic technology infrastructure that enables the IT realization of modularized, loosely-coupled, interoperable and runtime-managed business services (as business capabilities) that underpins the business process management framework, wherein the business services can be dynamically orchestrated in runtime environment to compose, execute and monitor end-to-end business processes. W3C Definition A set of components which can be invoked, and whose interface descriptions can be published and discovered. What is SOA

24 February 2016 What is SOA A service-oriented architecture (SOA) is an application framework that takes everyday business applications and breaks them down into individual business functions and processes, called services. SOA lets you build, deploy and integrate these services independent of applications and the computing platforms on which they run. An SOA frees service components from applications, so you can expose them to customers and partners

24 February Over the last few decades, the complexity of IT systems is ever increasing. The architecture and legacy systems are evolved over the time and its getting increasingly difficult for IT to cop-up with ever changing business needs and is always considered a bottleneck. This creates two major concerns for any organization. organizational lag Integration nightmares SOA helps to Respond to Business changes Address the integration issues Leverage the existing investments Why SOA?

11 24 February 2016 SOA Services

24 February Service can be defined as a self-contained piece of processing logic which has well-defined and discoverable interface through which the consumers (users) of the service can interact with it. In SOA, Services has got three properties Service has got well defined interface which is platform independent Service is dynamically locatable and invokable Service is self-contained Service does not expose “How” of the functionality exposed In the real life, we also offer and use services ! For example, You go to Restaurant look at the Menu Giver order to the waiter If the ordered item is readily available ( i.e. cold-drink) then it will be served immediately Else it will be served after some time and the restaurant may have its own mandate that they will serve in maximum n minutes and by that time item will be served to you What is a Service?

24 February Service Classification Service ConsumerService Provider Service Directory Discover and retrieve Services Description (WSDL) Publish Service Description (WSDL) Exchange Messages (SOAP)

24 February Traditional IT Service Approach - Dedicated resources, dedicated applications Redundancy XYWWW C Z B Business Unit I Business Unit II Corp Unit A Applications A, B and C all need Customer Information W = Similar ‘Get Customer Information’ applications Applications A, B and C all need Customer Information W = Similar ‘Get Customer Information’ applications

24 February SOA Approach - Shared Reusable Services Across Business Units XYW C Z B Business Unit I Business Unit II Corp Unit A Service Consumers Service Provider Components W = “Get Customer Information” as a shared service

24 February 2016 Challenges in SOA Testing Challenges in SOA Testing Agility and Time to Market Collaborative Approach Increased Dependency on Systems Lack of Front End GUI for validation
