SLA Violation Detection and Compensation in Cloud Environment using Blockchain

Abstract

The increased use of cloud computing technology and its wide adoption in the software industry has led to almost all modern consumer services being heavily dependent on the performance of the computing resources provided by the Cloud Service Provider (CSP). SLA which is agreed upon by both users and the CSP, plays a key role in keeping the performance of provisioned resources above a certain threshold. This SLA is enforced by CSP who uses the logs generated by the underlying machinery to monitor the performance of the machines and compensate the user. Similarly, a cautious customer might maintain its own monitoring mechanism to continuously evaluate the performance of the virtualized resources allocated to them. This creates distrust between the CSP and the client as both of them might not acknowledge the credibility of the other's monitoring mechanism and come at disagreement with each other on this. In this work, we propose a framework for SLA-violation detection and compensation using Hyperledger Fabric blockchain. Furthermore, we carry out the scalability and efficiency analysis Hyperledger Fabric network for the proposed system.
