Web Services and SOA

What is SOA?

Service Oriented Architecture (SOA) is an application framework that breaks everyday business applications into individual business functions and processes, called services. An SOA lets you build, deploy, and integrate these services independent of the applications and computing platforms on which they run.

Simply put, SOA means decoupling. In the history of software engineering, coupling between ‘pieces’ of a software system are like nails through pieces of wood: they make modification of the system design difficult, expensive, and time-consuming. With SOA, these problems can be overcome or at least minimized.

One of the other questions you should ask yourself and your company is, "what if we do not do SOA?" This is very important as it underlines what you or your company perceive as benefits from SOA. Your answer should have technical ramifications as well as business value attached to it. Some of them can be: ‘will not reduce costs of operations by 10%’, or ‘will not improve customer satisfaction by 20%’. Applying these types of metrics (business metrics), allows you to keep the end goal in mind as you delve into the technical aspects of the implementation. Also with that, the business value is usually greater than the project itself. In other words, you may be starting an integration project to service-enable applications, but your business value is visibility into customer purchasing habits.

Benefits of SOA:
  • With SOA, you build once and leverage repeatedly or ‘re-use’. It means each element of your business is captured and implemented in only one place. So, changing it is straightforward.
  • While re-use has benefits in development and maintenance costs, it also brings in the advantage of flexibility.
  • With clearly-defined interfaces between business systems, you can start modeling (and changing) the business process captured by them, at a level above individual systems or applications. Therefore, SOA enables process modeling at a truly enterprise scale.
  • It lets you compose new services out of existing ones, reducing the time of the Software Development Life Cycle. This in turn helps you respond quickly to changes and crunches the time-to-market.
The ability to compose new services out of existing ones has many merits. It:
  • Helps sellers demystify SOAs by demonstrating proven methods for implementing them efficiently.
  • Enables software across organizational and network boundaries to collaborate securely.
  • Makes it possible to use existing legacy applications via SOA wrapping.
SOA solution view of the SOA reference:Service characteristics:
  • An SOA is not only about exposing how you can call a service but also defining a set of characteristics for how these calls will be serviced:
  • "Service Oriented Approach (SOA) is differentiated from other technologies is not the service capabilities, but the service characteristics".
  • Characteristics of SOA are its
  • Performance,
  • Availability,
  • Capacity,
  • Quality of service,
  • Security.

Business Integration

Our BPM solutions help you manage processes and rules to conduct business faster, and in a smarter and more efficient manner. Our BPM offering using webMethods equips you to meet the challenges of managing an ever-changing business. We help you leverage your investments in legacy systems and provide seamless integration with visibility of business processes, using Business Process Modeling.

Thought methodology:

Our methodology is based on our experience in and the best practices of the industry. We address complex integration challenges with simple solutions in webMethods. We use webMethods's GEAR methodology effectively for designing high-availability architecture, for capacity planning, security, canonical strategy, performance tuning, change management, and collaborative development environment setup.

The inception phase involves making a detailed analysis of the enterprise systems, applications, platforms, and processes that need to be integrated.

This is followed by the definition phase, where the interfaces for implementation are identified and a detailed Integration Requirements Specification document is created. During this phase, the architecture and high-level design specification are built, and a Proof-of-Concept is carried out to validate the architecture and bring out the complexities involved.

The implementation phase involves coding and testing of adapters, mapping, transformation, routing rules, and building business processes. The interfaces are developed and tested in multiple iterations rather than in a one-iteration approach.

Then, during the testing phase, the interfaces are tested end-to-end across disparate applications and platforms.

Technical expertise:

The Infotalk integration team consists of experts in webMethods EAI, B2B and BPM tools and methodologies. Our team has been providing quality services and consulting support to fortune 500 companies for many years.

Benefits of Custom Application Development:

The closest relationship of a software company is with its client. To maintain a close-knit relationship, the company needs to make the implementation and execution of the client's requirement its utmost priority. At a stage when business firms are striving to become unique achievers, a simple software package with readymade applications may restrict their winning possibilities.

For procuring uniqueness in business objectives, customized or customer-friendly software is the best option. The role played by custom software development brings output as desired by the client. Customized software is prepared on the basis of the requirements and preferences of the client.

Procuring perfect custom software as the end product is not easy. It requires rigorous probing to understand, analyze, and accurately implement the ideas to result in a product. Again, pre-developed software may be less expensive, but the development of custom software is due to intrinsic research and excess requirements as the product has to be a client desired output.

The utilization of custom software procures faster, quality business results for the cost savings. A process-driven working model is followed by such companies which also involves pilot run and quality assurance tests.

The team involved in developing custom software has sound domain knowledge and also is well aware of the competitors in the business. In a fast paced business world where every firm is ready to outdo the other, working with a software that suits and is modified to the company’s needs and preferences is a viable option or lets say is a customized option.
