This model represents the Ea2Sa Microservices Platform Architecture, a cloud-native, service-oriented environment deployed across a hybrid on-premise physical cluster consisting of a Dell PowerEdge server and multiple Raspberry Pi 5 nodes. The architecture integrates business services, API-driven application services, containerized microservices, observability components, integration middleware, and infrastructure technologies to support a modular and extensible enterprise platform. The architecture is structured according to ArchiMate layers, illustrating how business capabilities are realized through application services, which are in turn supported by software applications, middleware, and physical infrastructure.
