Deploying and managing, in an efficient and adaptive way, complex multi-service applications over technologically dissimilar cloud environments is one of the problems that have emerged with the cloud revolution. In this work, we have studied suitable techniques to determine the distribution of application modules onto multiple available clouds while respecting QoS (Quality of Service) properties and technology requirements specified for individual application modules. For this purpose, we have proposed parametric allocation algorithm based on three selection criteria, i.e., Cost, QoS and Hybrid (Cost and QoS). In order to maximize the performance of the whole application—when the performance of the whole application is dominated by the performance of communicating modules—we have proposed the allocation of intensively communicating modules on a single provider using the same selection
criteria (Cost, QoS and Hybrid).
