In most cases legacy applications serve crucial business needs and are well entrenched in organizations. Maintaining such applications will however, become increasingly difficult and costly over time. Additionally providing access to such applications to more users both internally and to customers will become an infrastructure nightmare.
Web enabling such applications is a great way to make the application investments continue to be of value. Telliant has a great deal of experience in web enabling legacy applications quickly and efficiently. We use a variety of proven tools and techniques to make the process smooth and preserving the function rich value of the applications.
As applications age, the source code may become harder to maintain and inefficient as it has been updated several times and possibly by several people and often without consideration given to the original design and architecture. Such legacy code will prove too costly to maintain as is and would become a great candidate for re-factoring. Refactoring involves re-writing and re-structuring parts or all of the code to make it easier to maintain and support, and make it efficient and optimal.
Telliant believes in structured code development with a focus on efficiency, maintainability and extensibility. Using standardized design patterns and developing re-usable components make applications run consistently and predictably. Based on the application languages, Telliant uses a variety of techniques to allow for better abstraction, logical segmentation and re-usability. Documenting the code is crucial to achieve better maintainability.
Legacy systems are typically very critical to the operation of many organizations. Converting them to a modern architecture and technology platform may become a necessity for such organizations.
Challenges in modernizing legacy applications include user re-training, transition management and training support personnel. Telliant has experience in such conversions using a Service Oriented Architecture (SOA) approach and other techniques to manage the conversions effectively. Telliant has knowledge and experience in selecting the right technology platform and designing the most appropriate architecture for the client.
With the adoption of web as a central delivery platform for applications today, there has been a virtual explosion of available data visualization and UI/UX tools and techniques.
