Migration from Legacy systems

Several IT organizations have spent huge amounts of resources on their existing legacy applications which have huge amount of knowledge stored within them and day to day business processes are intricately woven around these systems. But with the advent of cloud and collapsing of boundaries, these legacy systems have become huge bottle necks for companies looking to expand over the cloud and take their business processes to a higher level. These legacy systems are not necessarily main frame systems but also various other applications that the company has been using to run its business operations from enterprise wide packages to client server software.

Several companies look forward to leverage their legacy systems over the cloud because they can re-use the existing logic supporting their various business organizations. Also cloud enabling a legacy system would be “fast to market” since the new system is based on existing legacy elements. Shorter ‘time to market” and ‘reuse’ of existing logic means lower costs to the company and also a system developed based on an existing system will be much more stable and secure.

The Cloud-Enabling Process

Legacy Assessment
The first stem in cloud-enabling a legacy system is to scan for and identify individual components. Scan and assess each the components, boundaries, dependencies, and functions. This assessment is vital and it lays the foundation for the re-architecture

Legacy Architecture

In order to re-architect and simplify existing processes it is very important have a clear idea of the legacy system’s architecture. The various levels of abstraction and the interaction between layers are analyzed. The analysis is charted out using call graphs, control flow graphs, structure chart etc.

Developing Wrapper Classes

Wrapper classes are classes which enable communication between the cloud components and the existing legacy components. Not all existing legacy components need to be leveraged on to the cloud. Only certain components are identified to be wrapped on to the newly developed cloud components.

Transformation to Web GUI

This is the final stage of cloud enabling the legacy system wherein the legacy UI are mapped or transformed into Web enabled GUI to be used in the web application.

Why Cloud enable legacy system services of KlioTech?

Customer centricity is the most vital aspect of cloud enabling legacy system. The cloud enabled system must be several level ahead of the existing system in terms of user friendliness, functionality, accessibility etc, for this customer centric development is the most vital and KlioTech does just that by lending an open ear to customers feedbacks, suggestions and ideas during the cloud enabling process.

Our process of legacy to cloud transformation process uses phased methodology to ensure a smooth transformation and easy leverage of the legacy system on to the cloud.
