Cloud computing has emerged as a popular paradigm that offers computing resources (e.g. CPU, storage, bandwidth and software) as scalable and on-demand services over the Internet. As more players enter this emerging market, a heterogeneous cloud computing market is expected to evolve, where individual players will have different volumes of resources, and will provide specialized services, and with different levels of quality of services. It is expected that service providers will thus, besides competing, also collaborate to complement their resources in order to improve resource utilization and combine individual services to offer more complex value chains and end-to-end solutions required by the customers.
