SOA is an architectural paradigm for building distributed systems from loosely coupled services. It allows different systems with different owners to interoperate. Key concepts of SOA include services, interoperability, and loose coupling. Realizing SOA requires the right infrastructure, architecture, processes and governance to handle heterogeneity and flexibility across systems. SOA is not a specific technology, but rather a style of building applications.
Service Oriented Architecture.
SOA is a style of architecting applications in such a way that they are composed of discrete software agents that have simple, well defined interfaces and are orchestrated through a loose coupling to perform a required function.

A service-oriented architecture (SOA) is an architectural pattern in computer software design in which application components provide services to other components via a communications protocol, typically over a network. The principles of service-orientation are independent of any vendor, product or technology.

BUSINESS SILOS INTEGRATION USING SERVICE ORIENTED ARCHITECTUREIJCSEA Journal
Agile integration satisfies the business agility and provides solutions for maintaining business changes and ensures that the enterprise survives in the current competition. Any business should be robust enough to respond to end user request. Existing traditional enterprise applications are in-capable of integrating with
different business silos lacks to improve the business agility. To address this issue, this paper is about the agile integration of different business silos using “Service Oriented Architecture” and its core technologyenables the business enterprise systems flexible, loosely coupled and improves agility. Enterprise business
systems have to adopt Service Oriented Architecture (SOA) as it promises to help them respond more rapidly to changing business requirements by composing new solutions from existing business services. Here the definition of SOA, its layers and the core technologies have been discussed.

5 ijitcs v7-n1-7-an empirical study on testing of soa based servicesAbhishek Srivastava
Service-Oriented Architecture (SOA) removed the gap between software and business. Today, there is a business transformation among enterprises and they adopt a service based information technology (IT) model. So, testing is necessary for SOA based applications. This paper investigates different type of approaches and techniques that address the testing problems of SOA based services. Here we also investigate the differences between SOA and web services and traditional testing and SOA testing. Various testing levels are also discussed in detail. This paper also expresses various testing perspectives, challenges of SOA testing and review the many testing approaches and identify the problems that improve the testability of SOA based services.
This presentation is an overview of a new and comprehensive enterprise integration practice based upon SOA... Services Oriented Integration extends SOA to cover what's necessary to ensure SOA actually works.
MULTIVIEW SOA : EXTENDING SOA USING A PRIVATE CLOUD COMPUTING AS SAAS AND DAASijseajournal
This work is based on two major areas, the Multiview Service Oriented Architecture and the combination between the computing cloud and MV-SOA. Thus, it is suggested to extend firstly the service oriented architecture (SOA) into an architecture called MV-SOA by adding two components, the Multiview service generator, whose role is to transform the classic service into Multiview service, and the data base, this component seeks to stock all of consumer service information. It is also suggested to combine the computing cloud and Multiview Service Oriented Architecture MVSOA. To reach such combination, the
MVSOA architecture was taken and we added to the client-side a private cloud in SaaS and DaaS.
SOA is becoming important for Business Process Management and Enterprises. Now SOA is widely used by Enterprises as it provides seamless environment, flexibility, interoperability, but at the same time security should also consider because the basic SOA framework doesn�t possess any security. It depends upon the respective proprietor for security [1]. In recent times many research work had done for SOA security. Researchers have also proposed various frameworks and models such as FIX [2], SAVT [3] which tries a lot, but cannot achieve any landmark as they are based on XML schema.This proposed novel work contains an inbuilt security module which was based on PKI. At the same time this model will intact the flexibility and interoperability as the security module is embedded by analyzing the nature of WSDL, UDDI, SOAP and XML. These protocols are also compatible with PKI. Proposed Model was implemented in the asp.net environment then experimental results are compared with other security methods such as data mining based web security and automata based web security

Chapter Two: SOA
IT-Slideshares http://it-slideshares.blogspot.com/
2. 2.1 Definitions of SOA
SOA is a paradigm
(style, perspective, concept, representation or philosophy)
that leads to a value system for large distributed systems
with different owners.
SOA is NOT a concrete tool or framework.
SOAs comprise loosely coupled, highly interoperable
application services.
A SOA is independent of development technology (such as
Java and .NET)
The software components become very reusable because
the interface is defined in a standards-compliant manner.
3. 2.1.1 SOA is a Paradigm
SOA is not a concrete architecture: it is something that
leads to a concrete architecture.
SOA might call it a
style, paradigm, concept, perspective, philosophy, or
representation.
You can't buy SOA. There is no tool or recipe you can
use to make everything work.
You must make specific decisions that are appropriate
for your circumstances.
4. 2.1.2 SOA Improves flexibility
The key reason for using SOA is that it should help you in
your business
A critical factor for business success these days is keeping
time to market share. E.g.
You can rant and rave all you want about software quality (or
lack thereof), but the marketing guys run the world, and they
want market share now . . . period, end of discussion. My job
is to deliver on time, on budget, with the "appropriate" quality
metrics.
Flexibility has a lot to do with clear
organization, roles, processes, and so on. Therefore, SOA
has to deal with all these aspects.
5. 2.2 SOA Drivers: Distributed Sys
Distributed Systems: SOA is well-suited
Different Owners:
The OASIS SOA Reference Model's definition of SOA
continues by stating that those distributed capabilities
"may be under the control of different ownership
domains.
SOA includes practices and processes that are based
on the fact that networks of distributed systems are
not controlled by single owner.
6. 2.2.2 SOA Drivers:Different Owners
you have to compromise with others, and you have
to accept that different priorities and solutions
exist
7. 2.2.3 SOA Drivers: Heterogeneity
Large systems use different platforms, different programming languages (and
programming paradigms), and even different middleware. They are
heterogeneous. Similar to "agile" methods of software development, which
accept that requirements change instead of trying to fight against those
changes, SOA just accepts that there is heterogeneity in large systems
8. 2.3 SOA Concepts
Services
The goal of SOA is to structure large distributed systems based on the
abstractions of business rules and functions.
A service is an IT representation of some business functionality
at this level of abstraction, platform-specific details don't matter.
Thus, platforms can be heterogeneous.
Interoperability
for SOA, high interoperability is the beginning, not the end.
Loose coupling: Minimizing dependencies, boost scalability. SOA has
goals. And remember, SOA is only a paradigm, not a recipe.
Flexibility
Scalability
Fault tolerance
9. 2.4 SOA Ingredients
You can’t buy SOA.
Need the right degree of centralization, set up corresponding processes, projects.
Infrastructure
The infrastructure of a SOA landscape is called an enterprise service bus (ESB).
The key feature of the ESB is that it enables you to call services between heterogeneous systems. Its
responsibilities include data transformation, (intelligent) routing, dealing with security and
reliability, service management, monitoring, and logging.
Architecture
OASIS SOA Reference Model Definition of SOA
Web Service-based architectures and technologies are specific and concrete. While the concepts in the
Reference Model apply to such systems, Web Services are too solution specific to be part of a general
reference model.
Processes
Business Process Modeling (BPM)
Model-Drive Software Development (MDSD)
Governance
Set up the right process to establish SOA in your organization
Finding the right people who are able to combine all the different SOA ingredients,
SOA competence center deals with infrastructure, architecture, processes …
Understanding Governance, management support, doing the right homework are key success factors
10. 2.5 SOA Is NOT a Silver Bullet
SOA is the ideal solution for very special
circumstances: heterogeneous distributed systems
with different owners.
But there's a price to pay for dealing with
heterogeneity and different owners, and providing
flexibility, scalability, and fault tolerance.
If you have everything under control (i.e., a
homogenous system and/or no different owners), SOA
might be pointlessly expensive for you.
11. 2.6 SOA is Not a Specific Technology
SOA is the paradigm; Web Services are one possible
way to realize the infrastructure by using a specific
implementation strategy.
Web Services are emerging as the de facto standard for
SOA implementations.
Web Services might help provide the
infrastructure, but you will still have to construct the
architecture, and set up all the complicated processes.
Web Services standard is not mature.
SOA with other technologies (CORBA, MQ, TIBCO
…etc)
12. 2.7 SOA Versus Distributed Objects
The idea was to enable remote access to objects of
external systems.
Distributed Objects approach was having one general
business object model spanning distributed systems
which may be hard to organize, too much
centralization, and too many dependencies.
With SOA, data is exchanged between different
systems, and each system operates on its local
(redundant) copy with its own local methods and
procedures. Unlike with distributed objects, this
approach decouples the systems and lets them scale.
13. 2.8 SOA Terminology
A provider is a system that implements a service (a
business functionality) so that other systems can call
it.
A consumer (requestor) is a system that calls a service
(uses a provided service).
If you want to use a generic term for both the provider
and the consumer, you can use the term participant.
14. 2.9 Summary
SOA is an architectural paradigm for dealing with business processes distributed over a
large landscape of existing and new heterogeneous systems that are under the control of
different owners.
The key technical concepts of SOA are services, interoperability, and loose coupling.
The key ingredients of SOA are infrastructure, architecture, and processes (including the
meta-process of establishing SOA, governance).
The key success factors for SOA are understanding, governance, management
support, and doing your homework.
SOA is neither a specific technology nor a silver bullet. There are places where SOA is
appropriate and places where it is not.
Web Services are one possible way of realizing the infrastructure aspects of SOA. Using
Web Services is often recommended because it seems to be becoming established as the
standard technology.
