yuuvis® Momentum fields a core consisting of a small zoo of cloud-native microservices, which allows for high availability and scalability. The entirety of the core's functions is made available through the API-gateway as core API . Two services—three if counting in the API-gateway— serve the microservice architecture itself: ADMIN allowing service administration like restarting a service or changing its intended amount of instances, and CONFIG, reading, caching and delivering configuration information to the other services.
