Service Oriented Architecture

It is many times important for us to have service oriented architecture. It is a kind of paradigm that organize and use distribute capabilities that may be under other’s domain. It ensures a uniform way to discover desired effects.Many times it is flexible to design different phases of development. All the systems using Service oriented architecture may utilize different particular systems. It ensures a model or plan that will be followed for completing a certain work. It ensures the consistency of the services with respect to vision and roadmap. Here architectural process is followed for system orientation.

SOA is a must for any business firm at present. Using this we can quickly and cost-effectively give a response to the market on any state. Consumer can be aware about the web based application by this. Service oriented architecture also integrates various web based process using by using several implementations. Here functions are separated into distinct services to ensure the users to unite and use them again and again in the action of producing applications. The users interact here in a properly defined and shared format among multiple services. In case of software architecture gathering of decisions from everyone is required. Here various types components, their features and interactions are available.

For any business enterprise having complicated structure Service oriented architecture is must. It is impossible for a software company to run the development of parallel section without it. There is also some demerits of SOA. At first in all firms it is not possible to apply. In case of transaction and security it is not suitable.

It is a true that SOA is different from other integrated applications. It is a simple process and undoubtly acceptable for all. If we apply it once in your firm then you will thank yourself after seeing it’s result.

1. What is Service Oriented Architecture (SOA)?

SOA is an architectural approach that enables the automation of businesses and governments allowing for more efficient communication and smoother operation. It basically allows the computing assets and other diverse and incompatible infrastructures of a business enterprise to work together.

2. What Problems does SOA Service Oriented Architecture solve?

SOA mainly helps to solve the problem of communication. For a very long time, different computing assets were unable to communicate with one another making integration and expansion extremely difficult and expensive. This problem which is known as data silos arises from the development of different and specialized systems for all the different services within a business enterprise. For example, if all the accounting for a particular business enterprise is done using operating system A and programming language A and the management of customer relationships is done using operating system B and programming language B, it may be difficult to integrate the two systems without SOA.

3. Who needs Service Oriented Architecture?

Any business enterprise that has invested greatly in applications requires SOA. In addition, any software company that has developed several vertical applications and cannot afford to go through the process of rebuilding all the applications from scratch requires SOA.

4. Why Choose SOA?

There are two main ways of ensuring integration within the different systems/ applications and data silos in a business enterprise: scrapping the whole system and building another more integrated one from scratch or using SOA to work with the existing systems. Since the first option is a bit too expensive for most public and private enterprises, most business enterprises choose to use SOA.

5. What are the limitations of Service Oriented Architecture SOA?

Despite SOA’s many benefits, it does have its limitations. First of all, there are certain operational functions that are outside the scope of service oriented architecture. This includes functions such as transactions and security. However, there are quite a number of ongoing investigations that are aimed at finding a way to adapt SOA to quality of service.

6. What’s the difference Between SOA and other methods of Integrating Applications?

Unlike traditional application connections which are often tightly coupled, SOA simplifies application integration enabling businesses to adapt to changing business environments without having to make changes to all the connected applications. Service oriented architecture also works with a wide range of applications including custom RPG, CoBOL, 4GL, BPCS, System/21, PRMS or any other applications that use Synon/Lansa or Asset.

Information Technology (IT) has been given an increasingly greater role in providing solutions for businesses moving to the next level. The demand to improve the content and the delivery of these important solutions has increased. This has resulted in the consolidation of the responsibility for solution design within the role of a solution architect who serves a similar need as was created during the evolution of the construction industry.

Solution Architecture is undermined by its poorly understood role. Its value to technology dependent organizations is lost on those business managers who do not understand the role of the Architect. The lack of understanding or acceptance by members of the IT profession also undermines the role. Also lost is a chance to improve business efficiency, and create a more productive economy.

Understanding solution architecture begins with the very basic concept that before starting to build something, it pays to consider what’s being built and how it can be built.

Ideally, the solution is defined by the customer’s needs, by project constraints such as funding and timing, and the availability of technology options.

The selection, design and specifications of the solution are the responsibility of the Solution Architect. In simplistic terms: Solution Architecture bridges the gap between business requirements and what technology can provide.

The practical application of solution architecture means Architects must be able to relate to both members of the business community such as managers and analysts, and with technologists in their native terms. The solution architect must have superb communication skills combined with deep technical knowledge exhibited through the medium of creativity.

Solution Architects are nearly always hired for their technical expertise. This expertise can be separated into three categories: technology, domain and depth of experience.

Civil engineering architects who design skyscrapers are required to solve very different engineering problems than those who design dams. This division of problem solving also applies to Solution Architecture where the Architect must be aware of his domain.
