It is a
daunting task to keep up with the changes taking place in technology-based
sector. The advent of service oriented architecture and Web services makes this
‘keeping up’ even more important because these technologies are changing the
way the internal systems are built, especially those that support the
organization and the interaction of the internal and external system.
service is a tactical implementation of SOA or service oriented architecture.
It bridges the difference between IT and businesses through a set of
business-aligned services. This is done with the use of a special set of
patterns, design principals and techniques. World Wide Web Consortium has
defined web services as a software system that is designed to support the
interoperable machine-to-machine interaction over a network. Web service is a
set of tools that can be used in a number of ways. REST, SOA and RPC are the
most common methods of use.
Service oriented architecture
involves the organization, discovery and description of services that enable a
company to select, bind and implement a service over the Internet. SOA is
different from the service-based architectures that focus on protocols and
formats. Service based architecture is a part of SOA. The advantages of
implementing SOA include increase in the application and development enabling
you to align your business with the IT sector, more effectively. This can be
implemented by using the CORBA, MQ series and Remote Procedure Call or RPC
technology. However, the web service is rapidly becoming a set standard used to
support service-oriented architecture.
