Service Oriented Architecture

Features and Advantages

1. Service

Service is the fundamental theory of Service oriented architecture. They are variety of services offered in the directory of “Yellow Pages” such as, courier services, roofing services, and garage services. For every service a person or organization is assigned to offer something like transmit messages and goods, take care of vehicles, repair and installation of roofs on buildings-any service that would benefit other people or organization (Service customers). Services provide the following advantages:

• Improved Information flow: In contrast to large applications that could cause information silos and are often costly, SOA is finer-grained software that saves integration costs

Performance measurement enables designer of services to put real clauses into contracts, and this makes system managers to evaluate that the clauses are meeting the requirements.

• Security Attack Detection: message monitoring can provide detection of attacks in particular messages.

5. Message Control

Message control provides the following advantages:

• Functionality of management related policies: For example, by prohibiting a service customer to a particular service volume or giving priority to certain types of messages.

• Function of security policy: For example, by controlling accessibility to particular services or restricting messages that could damage the systems of the enterprise or the enterprise (e.g: viruses etc).

6. Message Transformation

Message transformation provides the following benefit:

• Data translation: the act of converting data from one format to another format. Data conversion through special-written software is costly but converting data through SOA is less costly.

7. Message Security

Message security provides the following

Hence this could be done by creating a new service for Internet cash payment and integrating in with the service.

10. Service Discovery

Service discovery provides the following benefit:

• Capability to optimize functionality, performance and cost: by choosing service modules by this criterion.

• Simplification to introduce system upgrades: ability to select available service upgrades and replace it with the old version.

11. Asset Wrapping

The IT assets of an organization are responsible to perform the services. Hence, for service provision a software and hardware assets are required.

With the adaptation of SOA the function of asset wrapping is applied to the existing software’s.

Asset wrapping provides the following benefit:

• Integration of existing assets: this serves the factor of assets preservation. The price of creating or buying replacements is avoided, and therefore smooth transfer from old to new architecture is possible.

12. Virtualization

The act of using multiple operating systems with a single computer unit is called
