What often began as a clever solution of a resourceful employee, is pragmatically expanded and thus quickly grows into an extensive and almost impossible to understand system. Everyone in the company knows that all this has to be “ironed out”. But the next order is prioritized, and after all, it is still working …
One way or another, software landscapes emerge over time that are deeply intertwined with various company processes, but are no longer expandable and maintainable due to technological and personnel reasons. The complexity of the old systems is thereby ever-increasing and hindering “new” solutions. A vicious circle begins.
Our offer
- Classification of Legacy Code
- Risk assessment
- Targeted architecture refactoring
- Maintaining the vital company functions at every stage
Our aim is that your legacy application is not only technologically rebuilt , but also provides immediate added value. That’s why we analyze your software and the business processes behind it, identify the components, and classify the legacy code. We provide you with a risk assessment of the modernization of your existing application. Based on this assessment, we can offer various options and prioritize them according to your requirements.
With our expertise and many years of project experience, we work together with you to develop and realize the best solution for your case. While in one case a comprehensive modernization up to a new implementation can be the most profitable solution, in other cases targeted adaptations and extensions lead to sustainable success.
Example architecture refactoring of a legacy application
Extract microservices
Gradually identify isolatable functionalities and extract them as microservices or reimplement them.
Set up service layers for protection
A service layer as an interface between the existing system and the new microservices can serve as a so-called anti-corruption layer, which prevents poor design and malfunctioning of the legacy system from undesirably affecting the new microservices.
Monitoring
In all phases of this transformation, a uniform monitoring system ensures that operation is fully guaranteed.
