As industries increasingly embrace digital and intelligent transformation, enterprises face significant challenges in the containerization upgrades for their Artificial Intelligence(AI) applications and dynamic service migration and management in Cloud-Edge continuum(CEC). This paper presents CloudSkin, an innovative platform designed to realize streamlined, seamless and intelligent service migration in Cloud-Edge Continuum by integrating advanced containerization techniques and AI-driven orchestration capabilities. Our approach, leveraging intelligent algorithms for service migration, can seamlessly transit services between cloud and edge environments, ensuring optimised resource allocation and reducing service latency to assure quality of service(QoS). CloudSkin has been enabled in a Mobility Usecase, empowering Cellnex businesses undergoing digital transformation to achieve higher operational efficiency. The experimental results show that compared to traditional reactive service migration, using intelligent proactive service migration can provide better migration detection, improving F1-Score up to 23.5%, and reducing 28.9% the service running time where the service latency violates SLA.

Machine Learning (ML) is becoming pervasive and integrated into different kinds of intelligent applications, and the collaborative Cloud-Edge continuum has been introduced as an emerging trend to support their adoption into use cases. However, managing these ML applications in the CloudEdge continuum is challenging due to the ML application's dynamic resource usage with different user loads and Cloud and Edge's dynamic resource availability. We envision machine learning methods that can be used for smart management in this dynamic environment, but how to deploy and utilize them for the adaptation scenario in Cloud-Edge continuum is unknown. This paper proposes an agent-based framework to enable autonomous smart management mechanisms that can be broadly enabled in diverse adaptation scenarios. The agent acts as a data-connector11https://github.com/bsc-scanflow/data-connector, connecting different sources of data, utilizing ML models for decision-making and triggering adaptations in Cloud-edge platforms. The case study shows the feasibility of our proposed data-connector for smart migration of an ML workload in the Cloud-edge continuum. The result shows that the smart migration-enabled Cloud-edge scenario has 11.9% ML application prediction time better than the Cloud scenario without migration. Moreover, with minimal customization, the data connector agent can be adapted for more use cases.
