Transformation without impact

Transformation without impact

 

The devops and cloud help integrate and produce microservices on industrial scale, but these are still would not replace fully the layers of legacy code, and thus the middleware technologies are to be brought into the digital transformation process.

 

There are new languages on the server and client side and the software development techniques and tools that address the needs of the web applications, but to develop business logic one needs to move to the distributed computing the systems with libraries that are filled with the code that initially were on the mainframe. Some companies adopted this from the start, but others started in the older computing generation environments, such as mainframes. These companies still speak the Cobol or Natural language to connect IT and Business. At the same time, these companies are also adopting the later technologies to insure the web and mobile presence. Apparently, the legacy development involves people for eternity, and very few make it to understand and master other technologies. The legacy software and hardware vendors do not stop at spending to provide the top class development integrated development environments to relook the legacy code from the contemporary perspective. The old languages are applied in the new environment of web protocols and latest development tools, making it attractive for the IT professionals who must maintain their critical skillsets in the competitive marketplace. This is part of the solution going forward, but it limits the legacy applications to the services to be used by the transforming enterprise. The services require the procedural programming that is not the most efficient, although in some cases is the best solution.

 

In general, the business logic comes with the visual aids such as screens because the business logic needs to be understood by people, often and preferably visually. This makes the screen coding much more attractive in the monumental legacy rewrite process. The screens sessions become the part of the web navigation process through the optimisation of the recorded code. The mainframe feel and look appears present in the instant transformations, but the smart tools provide the transformation logic to change the HTML drastically. The modern looking interfaces do resemble the technical and systems feature of the legacy maps, but do not present the typical technological barrier to the business users who are accustomed to work with the old systems.

 

The screen emulation approach has an advantage of almost not having to change any of the backend code, to minimise the effort of the legacy business systems maintenance. The emulation is working for the contemporary web pages as well to merge both worlds in one reasonably modern web interface. Although, the customers most certainly will want to leverage the web services of the legacy environments, so this will be also provided in the same virtually non-intrusive matter by scrapping the data from the screens into the service memory to be processed and shared with the customer as the business payload. It happens from time to time to address the issues on the backend, but it is always the case to improve the legacy code, as the emulation tool at the same time is a testing tool for the legacy applications.

 

The cost of such web development will be a fraction of the traditional API driven architecture approach through the pre-existent and so virtually change-free business interfaces and back-end business logic as well as the data models optimised through the years on running on the mainframes. The required changes are adhered to through the stylesheets and adjustment cosmetic backend modifications. With such speed of development and cost cutting the seamless transformation will allow to transfer the business data views and business functions APIs to the web applications in cloud and on premises.

 

middleware technologies also known as mWtech provides the architectural and engineering services to leverage these transformation platforms for the transformation of the legacy integration into the contemporary computing environments.
