This letter 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. We 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. We propose a novel combinatorial auction‐based cloud market model that enables a DC platform among CPs. We also propose a new promising multi‐objective optimization model to quantitatively evaluate the partners. Simulation experiments were conducted to verify both of the proposed models.
