API-led Connectivity and CQRS: API layering and the CQRS API implementation

In this 4 part blog series, I describe in detail how one might go about modernizing a functional, but legacy Supplier Relationship Management (SRM) application without redeveloping (or even touching) it. Why? The release cycle for the legacy app is too long and it doesn’t scale in a way that will meet the needs of newly required mobile application.

Additionally, an aspect of SOLID software design is the Open/Closed Principle which in our case can be applied as we are extending and providing functionality without actually modifying the core application.
