Creating and maintaining the software architecture

The goal of the project is to replace a monolithic software architecture based on the Model-View-Controller software pattern with a modular, high-performance, distributed and thus easily scalable application for use on dedicated servers, in the public cloud, on-premises, and as software as a service

The use of software patterns ensures that only one codebase is needed for the different deployment types
