SLA Violation Detection in Multi-Cloud Environment using Hyperledger Fabric Blockchain

The increased usage of cloud computing technology and its industry-wide adoption has led to almost all modern consumer services being heavily dependent on cloud computing platforms. The user and the Cloud Service Provider (CSP) must agree on a Service Level Agreement (SLA) to keep performance above a given threshold and maintain a certain Quality of Service (QoS) (quality of service). This SLA is enforced by the CSP, who monitors the performance of the computers and compensates the user using the logs created by the underlying machinery. Similarly, a cautious customer can keep a monitoring system in place to examine the operation of the virtualized resources assigned to them regularly. This leads to distrust between the CSP and the customer, as neither party believes the other’s monitoring system is reliable. In this work, we propose a blockchain-based which guarantees the integrity of the client’s logs and verifies the SLA violations creating a trustworthy ecosystem. Furthermore, we carry out the scalability and performance analysis of proposed system using Hyperledger Fabric blockchain platform.
