Effectively managing decentralized applications in cloud environments using a decentralized control paradigm is essential, as current cloud providers usually only offer a control interface for monitoring cloud infrastructures. This study proposes a decentralized service control framework for implementing the control across various organizations and coordinating collaboration among operators in a decentralized application. The proposed framework allows a consortium of organizations to control a shared distributed cloud infrastructure decentralized reliably. A consensus mechanism within the framework enables mutual coordination between the operators. This mechanism also uses an incentive protocol to enforce pro-active behavior and collaboration. We implement the framework with Hyperledger Fabric, and our experiments demonstrate its usability, reliability, and acceptable performance.
