The rapid growth of Internet of Things (IoT) devices and emerging technologies, along with the growing demands of edge-deployed applications, has led to a complex paradigm where computation often shifts dynamically acrooss the IoT-Edge-Cloud continuum. The NEPHELE project addresses these complexities by enabling seamless orchestration across a diverse spectrum of computing resources, spanning multi-cloud environments to the far-Edge. In this paper, we present NEPHELE's multi-cloud infrastructure, built to overcome key orchestration challenges within cloud and edge environments. We discuss the core components and architectural decisions, focusing on multi-cluster resource orchestration mechanisms, integrated monitoring for local and multi-cloud systems, inter- and intra-cluster scaling, and networking capabilities. Experimental results demonstrate the efficiency of our infrastructure, highlighting overhead management in service deployment, migration, networking, and scaling scenarios, thus highlighting NEPHELE's robustness in handling distributed applications across heterogeneous environments.
