This paper presents a model for a Dynamic Collaboration (DC) platform among Cloud Providers (CPs) that prevents adverse business impacts, cloud vendor lock-in and violation of service level agreements with consumers, and also offers collaborative cloud services to consumers. The authors consider two major challenges. The first challenge is to find an appropriate market model in order to enable the DC platform. The second is to select suitable collaborative partners to provide services. They propose a novel combinatorial auction-based cloud market model that enables a DC platform among CPs. They also propose a new promising multi-objective optimization model to quantitatively evaluate the partners.
