Service Oriented Architecture Different Things to Different People Roles
A model of the business and related key performance indicators
Business
An architectural style which requires a service provider, requestor and a service description. It addresses characteristics such as loose coupling, reuse and simple and composite implementations.
Architecture
A programming model complete with standards, tools, methods and technologies such as Web services
Implementation
IBM IT Service Management
A set of agreements and contracts among service requestors and service providers that specify the quality of service. 7

SCA enables SOA flexibility SOA is the architectural style that supports loosely coupled services to enable business flexibility in an interoperable, technology-agnostic manner. SOA consists of a composite set of business-aligned services that support a flexible and dynamically re-configurable end-to-end business processes realization using interface-based service descriptions.

What is loose coupling? Tighter coupling tends to cost more over time – Synchronizing multiple organizations on change – Hard to move, hard to scale, hard to distribute, hard to replace – Making changes is hard and expensive, or impossible: • Knowledge is distributed throughout the code • Same people are solving business and infrastructure problems
– Different parts of the solution are difficult to manage separately – Adapting, redeploying updated components without affecting others
Looser coupling requires greater investment up front – More design work – More implementation work

Application functionality is tightly bound to a static notion of a process
Little flexibility to take into account new roles or processes

Applications Infrastructure
Management is focused on the health of the server, network and middleware
This creates redundant code and functions. Inflexible, expensive and hard to maintain.

ESB is still an “Architectural Pattern” “ We
describe the enterprise service bus first and foremost as an architectural pattern. In fact, it is possible to construct service buses from a variety of different underlying integration technologies.
The announcement of a WebSphere ESB has caused some confusion as it would appear on the surface that IBM has done an about-face to say that the ESB is now a product. To be clear, IBM believes that an enterprise service bus is an architectural pattern.
21

ESB is still an “Architectural Pattern” WebSphere ESB is in fact, an ESB-centric product, which facilitates the creation of specific instantiations of that pattern. The architecture pattern remains valid and is a guiding principle to enable the integration and federation of multiple service bus instantiations.”

What is an Enterprise Service Bus (ESB)? A flexible connectivity infrastructure for integrating applications as services… ……which reduces the number, size, and complexity of interfaces. An ESB: ` VIRTUALIZES the location and identity of participants ` CONVERTS between different transport protocols used by the participants ` TRANSFORMS message formats between participants ` APPLIES appropriate qualities of service for the given interaction ` DISTRIBUTES business event information to/from disparate sources. 23

ESB Transport Protocols and Conversion Basic connectivity supported via one or more transport protocols – Dependent on underlying communication fabric(s)
Conversion inherent with support for more than one transport protocol Enables – Virtualization of interaction protocol – Aspects of QoS (e.g., reliable delivery, transactions)
Typical requirements – HTTP (SOAP/HTTP, XML/HTTP) – MQ (SOAP/JMS/MQ, XML/MQ, text/MQ, …) – Adapters (legacy, EIS)
Standards important – WS-I, … 42

Provides common representation of content exchanged between services
Structured content includes body content (Business Object) and headers
Headers include transport-specific data (e.g. JMS headers and properties, SOAP headers, MQ headers)
Logical structure accessible using XPath and SDO APIs
SMO is implemented as a specialization of Business Object
IBM WebSphere Day 2009
Summary …
Mediations are designed to transform and route data content Primitives are the tools that make that possible There are many provided primitives as well as the ability to design your own custom primitives The SMO API is the programming model for all WebSphere ESB mediations
