On-Demand Bundling of Cloud and Edge Services
摘要
This paper discusses and demonstrates the bundling of cloud and edge services despite their non-functional discrepancies in terms of more resources/reliability/latency for cloud and less resources/reliability/latency for edge. While existing bundling guidelines target cloud services, only, bundling edge services could tackle cloud services’ data-freshness and data-security shortcomings. The proposed guidelines build upon the concept of capacity to represent bundled cloud/edge services, coordination relations to avoid conflicting bundled cloud/edge services, and a policy language for instance, the Open Digital Rights Language, to define what can be, cannot be, and must be exercised on bundled cloud/edge services. For validation purposes, a prototype implementing bundling of cloud and edge services for next-generation autonomous-cars is developed, deployed, and evaluated. The experiments’ results show that bundled cloud and edge services offer a convenient trade-off between computing power and low-network latency.
