An auction and witness enhanced trustworthy SLA model for decentralized cloud marketplaces

Cloud computing has become one of the most important technologies that have changed the traditional application development and operation (DevOps) lifecycle. However, current cloud software DevOps often faces the following key challenges: 1) selecting the best fitting service providers, customizing services and planning capacities for large-scale distributed applications; 2) guaranteeing high-quality and trustworthy service level agreements (SLAs) among multiple service providers; 3) enhancing the interoperability of cloud services across providers; 4) designing incentive model effectively among players. In this study, a framework called AWESOME is proposed to build a decentralized cloud marketplace and to address the above challenges. The proposed framework contains four subsystems including a customizable auction model, an incentive witness mechanism, and a social behavior-based simulator as one automated framework. We also provide a proof of concept to demonstrate that the AWESOME framework is feasible.
