Legacy Application Integration

Legacy systems were developed with the scope, functionality and features that met requirements at the time that they were created. Over time, as environmental factors change, organizations grow and technologies evolve, those systems may no longer fully meet expanded needs. Amazingly more powerful processors, storage potential orders of magnitude larger and very high-speed bandwidth enable effective integration of systems that have historically been operated separately.

Client Situation

Systems that were developed with limited scope within one functional unit may need to be integrated with functionality embedded in a system developed in a separate business functional area or operating unit. This situation is characterized by:

• multiple applications that are limited in scope or functionality
• separate databases that contain only a subset of the enterprise view
• complex systems that would be difficult and expensive to consolidate, or
• performance that is reliable and fast, with large capacity.

The need for application integration is especially high in the case of mergers and acquisitions. To get the most value out of strategic growth, the infrastructure and operations of the parent organizations must be integrated quickly and effectively.

IAI's Solution

IAI can integrate independent systems based in diverse environments to provide a unified user interface and consolidated data output. From the user’s perspective, the integrated system appears to be one, seamless whole, even though the solution retains its core components. Using SOA, web services are created for the core business processes of each source system. The web services are consumed by a common, web-enabled graphical user interface. This reuses the existing components of multiple legacy systems, while fulfilling the broader needs of the organization.

Value of this Approach

Integrating existing systems enables organizations to provide broader functionality and consolidate operations quickly. By reusing legacy system components, this approach contains costs and limits risk.
