Abstract	Smart-city services are typically developed as closed systems within each city’s vertical, communicating and interacting with cloud services while remaining isolated within each provider’s domain. With the emergence of 5G private domains and the introduction of new M2M services focusing on autonomous systems, there is a shift from the cloud-based approach to a distributed edge computing paradigm, in a continuum orchestration. However, an essential component is missing. Current orchestration tools, designed for cloud-based deployments, lack robust workload isolation, fail to meet timing constraints, and are not tailored to the resource-constrained nature of edge devices. Therefore, new orchestration methods are needed to support MEC environments. This article addresses this gap. We propose an orchestration platform and its algorithms to facilitate the seamless orchestration of both cloud and edge-based services, encompassing both critical and non-critical services. This work extends the current Kubernetes orchestration platform to include a novel location-specific resource definition, a custom scheduler to accommodate real-time and legacy services, continuous service monitoring to detect suboptimal states, and a refined load balancing mechanism that prioritizes the fastest response times. © 2008-2012 IEEE.
