Towards an API-driven Approach for Universal and Lightweight Cloud-Edge Orchestration
Sebastian Böhm, Guido Wirtz · 2024
Service placement in cloud-edge environments is complex because workloads must be placed on constrained nodes based on particular objectives, like response time, energy, or cost. Many advanced techniques emerged over time to tackle this issue. However, real-world experiments are the minority. Theoretical and simulation-based evaluations are prevalent. We present a Platform for Universal and Lightweight Cloud-Edge Orchestration (PULCEO) to foster real-world evaluations. It supports creating, operating, monitoring, evaluating, and documenting orchestration solutions via a RESTful API. For evaluation, we performed a case study. We used PULCEO to reproduce a representative and theoretically designed solution for service placement in a real-world environment. Our platform can transfer theoretical orchestration solutions to realworld environments. Consequently, our platform simplifies real-world experiments with topology creation, dynamic link quality measurement, evaluation, and documentation automation.
