The management of Service-Level Agreements (SLAs) in Edge-to-Cloud computing is a complex task due to the great heterogeneity of computing infrastructures and networks and their varying runtime conditions, which influences the resulting Quality of Service (QoS). SLA-management should be supported by formal assurances, ranking and verification of various microservice deployment options. This work introduces a novel Smart Contract (SC) based architecture that provides for SLA management among relevant entities and actors in a decentralised computing environment: Virtual Machines (VMs), Cloud service consumers and Cloud providers. Its key components are especially designed SC functions, a trustless Smart Oracle (Chainlink) and a probabilistic Markov Decision Process. The novel architecture is implemented on Ethereum ledger (testnet). The results show its feasibility for SLA management including low costs operation within dynamic and decentralised Edge-to-Cloud federations.

边缘到云计算中的服务级别协议的智能合约

边缘到云计算中的服务级别协议(SLA)的管理是一项复杂的任务,这是因为计算基础架构和网络的异构性很大,并且它们的运行时间条件也不同,这会影响最终的服务质量(QoS)。SLA管理应得到各种微服务部署选项的正式保证,排名和验证的支持。这项工作介绍了一种新颖的基于智能合约(SC)的体系结构,该体系结构可在分散计算环境中的相关实体和参与者之间进行SLA管理:虚拟机(VM),云服务使用者和云提供商。它的关键组件是经过特别设计的SC功能,不信任的Smart Oracle(Chainlink)和概率性的马尔可夫决策过程。这种新颖的架构是在以太坊分类帐(testnet)上实现的。
