Service
oriented architecture (SOA) refers to the use of loosely coupled software
systems and components that enable interaction and communication between IT
applications based on different technological platforms. People are generally
unaware about service-oriented architecture, because it is a relatively new
technological innovation. Although SOA is now being increasingly implemented in
all types of organizations, it is still a relatively little known technology, because
of its highly technical nature. The technicalities involved make it quite
difficult for normal people to understand what service-oriented architecture
is, and how it can be utilized towards benefiting a business organization. The
technicalities however should not dissuade people from understanding SOA,
because the basics are quite easy to understand. The technicalities can always
be set aside as long as an individual is not planning to make a career in
service-oriented architecture.

 

To
understand what service-oriented architecture is in detail, people can get help
from SOA books, journals, and magazines that are easily available in most
bookstores. They can also talk to firms that provide SOA related services, or
request free e-journals or e-books from them. On the other hand, individuals
who are planning to make a career in SOA, and need to learn the basics, can
enroll themselves for free online SOA courses that are easily available on many
Internet websites.

 

 


 

Service-Oriented
Architecture or SOA is an architectural approach to finding business solutions,
with the main aim of acquiring loose coupling amongst cooperating software
agents. Service can be defined as the work done by the service provider to
deliver satisfactory results for a service consumer. Software agents act as
both, providers as well as consumers.

 

The
principle behind SOA is very different from that of an Object-Oriented program,
where it is necessary to combine data and the processing. Service-Oriented
Architecture accesses all the different, distinct business functions in various
enterprises and arranges them to become interoperable services. This is very
useful in the exchange of information with reliable partners. However, organizing,
managing and revealing these services can culminate in a high security risk.

 

SOA
is the foundation of all Web services. Web services are the strategic
implementation of SOA that helps to bridge the gap between the IT sector and
businesses, by employing specific business-oriented services, exclusive
principles, designs, techniques and patterns. SOA comprises of the dynamic
innovation, description and organization of services that allows companies to
choose, combine and summon a particular service over the Internet. SOA is
different from other service-oriented architectures like OBI or Open Buying
over the Internet and RosettaNet that concentrate on protocols and formats. SOA
is a set of services that interact with each other.
