Software Parade; the fun way to create an overview of hundreds of applications in Neo4J

One of the challenges in a (micro-)service landscape is to keep track of all capabilities in the services. Another is to keep track of the consumers of your service and the consumers beyond. Taking our IT landscape as an example: we work with over 120 teams on over 850 different applications varying from services, GUI’s, services, data builders and other types of applications.
