System Integration



Consulting and Systems Integration Strategies service examines the dynamics affecting the C&SI services market by analyzing key trends and drivers and evaluating the competitive landscape for companies currently competing in, partnering in, or entering the market. This service also identifies and evaluates marketing and sales strategies, partnering approaches, pricing trends, business models, and global sourcing strategies of leading and emerging systems integrators.

Consulting
We help companies think ahead. Business today is evolving faster than at any other time in history, and tomorrow there are going to be challenges we can't even imagine today. And opportunities. But to survive and thrive, we must imagine that future. We must anticipate it.
Even while we're helping you solve your business challenges today, we're thinking about the future - and how we can take you there. Which is what gives you the competitiv​e edge in what's to come.

Competitive Advantages
Consulting can give you the business analyses you need and follow through with implementation. The world's leading provider of integrated business, technology and process solutions, we can deliver a depth of resources that's unsurpassed by other firms.
We have the flexibility to deliver solutions quickly and cost-effectively. And our confidence in our ability to think ahead makes us willing to be measured against any business outcomes. Which means that with Wipro Consulting, you get the advantage of future thinking - along with the advantage of being taken the rest of the way.

Systems integration
A system is an aggregation of subsystems cooperating so that the system is able to deliver the overarching functionality. System integration involves integrating existing often disparate systems. System integration (SI) is also about adding value to the system, capabilities that are possible because of interactions between subsystems.
In today’s connected world, the role of system integration engineers is becoming more and more important: more and more systems are designed to connect, both within the system under construction and to systems that are already deployed

Methods of integration
Vertical Integration
Vertical Integration (as opposed to "horizontal") is the process of integrating subsystems according to their functionality by creating functional entities also referred to as silos. The benefit of this method is that the integration is performed quickly and involves only the necessary vendors, therefore, this method is cheaper in the short term. On the other hand, cost-of-ownership can be substantially higher than seen in other methods, since in case of new or enhanced functionality, the only possible way to implement (scale the system) would be by implementing another silo. Reusing subsystems to create another functionality is not possible

Star Integration
Star Integration or also known as Spaghetti Integration is a process of integration of the systems where each system is interconnected to each of the remaining subsystems. When observed from the perspective of the subsystem which is being integrated, the connections are reminiscent of a star, but when the overall diagram of the system is presented, the connections look like spaghetti, hence the name of this method. The cost varies because of the interfaces that subsystems are exporting. In a case where the subsystems are exporting heterogeneous or proprietary interfaces, the integration cost can substantially rise. Time and costs needed to integrate the systems increase exponentially when adding additional subsystems. From the feature perspective, this method often seems preferable, due to the extreme flexibility of the reuse of functionality.

Horizontal Integration
Horizontal Integration or Enterprise Service Bus (ESB) is an integration method in which a specialized subsystem is dedicated to communication between other subsystems. This allows cutting the number of connections (interfaces) to only one per subsystem which will connect directly to the ESB. The ESB is capable of translating the interface into another interface. This allows cutting the costs of integration and provides extreme flexibility. With systems integrated using this method, it is possible to completely replace one subsystem with another subsystem which provides similar functionality but exports different interfaces, all this completely transparent for the rest of the subsystems. The only action required is to implement the new interface between the ESB and the new subsystem.

common data format
A common data format is an integration method to avoid every adapter having to convert data to/from every other applications' formats, Enterprise application integration (EAI) systems usually stipulate an application-independent (or common) data format. The EAI system usually provides a data transformation service as well to help convert between application-specific and common formats. This is done in two steps: the adapter converts information from the application's format to the bus's common format. Then, semantic transformations are applied on this
