Benefits, Advantage of Service Oriented Architecture (Web Serivce) Implementation - SRG Networks, Houston, Texas, USA

Enterprise Service Oriented Architecture

Technological changes are inevitable part of life and software industry is also part of that. We have witnesses drastic changes in the way software applications are developed and delivered in last few decades. Mainframe Cobol based application have been shrink into DOS system and DOS applications have been converted into rich windows based desktop applications. Internet and web based system have revolutionize the entire world in way business have been done and the way software applications have been used in late 80's and 90's. Millions of internet based companies have been mushroomed across the United States and rest of the world with emerging technologies and style of doing business. Traditional procedural based applications have been re-written in fourth generation programming languages (4 GL) that uses Object Oriented Analysis and Designing (OOAD) and Programming System (OOPS) concept. Companies have started offering online software services using Software-As-A-Service (SAS) model using combination of web based applications and web services. In 21st century, we are getting ready to take our OOPS application to a next level to achieve more efficiency and reduce IT cost by developing more maintainable and reusable software components using Service Oriented Architecture. There are lots of myths and facts about SOA and it remains secret for businesses and decision makers as why should they spend money into SOA based development. After all it's nothing but combination of web services developed to do exact same thing that their current applications are doing for their business. SOA have been taken to a next level to help large enterprises consist of hundreds of thousands of users, global office locations and numerous business divisions spanned across different countries executing business processes that is compatible with local law and enforcement laws. Enterprise IT inventory is filled with hundreds of proprietary applications individually developed and maintained by specific business division. Idea of Enterprise Service Oriented Architecture (ESOA) is to reduce these enormous amount of applications and develop a common platform that offers unique services that can be utilized company wide to bring uniformity and compliance standardization. ESOA is architectural concept of designing a software service (which can also be a web service) that provides necessary functionality using one of more complex applications.



Lets address some of the key questions about Service Oriented Architecture.

What good does it do for your business?
Why should you go for SOA?
What are key benefits / advantages of SOA?


1. High Return on Investment (ROI)
At enterprise level, corporations are undergoing many rounds of mergers and acquisition. Massive efforts have been executed to integrate large scale applications between two or more companies involved in a M&A. Enterprise Application Integration (EAI) tools definitely help in accomplish this task but EAI cost can be reduced by properly implemented SOA. Business processes replacement or modification can be simply achieved by integrating various services offered by your service repositories. Your list of services forms a repository that is out come of Service Oriented Architecture

2. Changing Business Scenarios
Business scenarios are changing everyday and it is crucial to change your IT applications to stay up to date with these changes in order to be competitive and maximize profits. SOA abstracts your core business rules and business components from the way it has been integrated with other applications to serve with data and information. For example, HR application is serving many partners application by serving business data. Due to recent change in new government laws, it is required to capture additional informational for a new hire candidate to for reporting payrolls and IRS dept. This change might cause in mal-functioning all dependent partner applications. This problem can be resolved by SOA, which uses HR applications and serve all partner applications (via web service) in providing necessary information. Changing in business process might result in changing SOA based application in the way it reads data from HR application. But this change is transparent to all partner applications. SOA reduces re-development effort for all partner applications and avoid application down-time to achieve efficiency.

3. Platform independent communication channel between IT Applications
SOA helps you implement communication medium between various IT applications such as legacy IT applications and latest web based RDBMS system. SOA introduce loosely coupled software modules (as a service) to be used by application independent of operating systems, networks and programming languages.
