A Blockchain Based Witness Model For Trustworthy Cloud Service Level Agreement Enforcement

Managing service level agreements (SLAs) in edge-to-cloud computing is a complex task that affects the resulting quality of service (QoS) due to the heterogeneity of computer infrastructures and networks and their different conditions of use. ALA management should be supported by formal assurances, rankings and revisions of various options for the provision of micro-services. This work presents an innovative intelligent contract architecture (SC) that enables SLA management between the entities involved and the players in a decentralized IT environment: Virtual Machines (VMs), Cloud Service Consumer and cloud providers. The most important components are specially developed SC features, a trusted Smart Oracle (Chainlink) and a probabilistic Markov decision-making process. Innovative architecture is implemented on Ethereum ledger (Testnet). The results show its feasibility for the management of ALS, including low cost exploitation within dynamic and decentralized edge-to-cloud associations.
