Recent rapid development of both networking and cloud computing technologies is transforming the Internet from an infrastructure for data transportation to a general platform for service provisioning upon which a wide spectrum of cloud computing applications can be deployed. Such transform requires networking and cloud computing to be integrated in the next generation Internet, which calls for federated management of both networking and computing resources for service provisioning. The Service-Oriented Architecture (SOA), which has been widely adopted in cloud computing through the IaaS, PaaS, and SaaS paradigms, has been applied in networking to enable the Network-as-a-Service (NaaS) paradigm. The NaaS in networking together with IaaS in cloud computing offers a promising approach toward converged network-Cloud service provisioning in the next generation Internet. A key challenge to achieve high performance converged network-cloud services lies in composition of network and Cloud services with end-to-end performance guarantee. In this chapter, we present our recent research progress in Quality of Service (QoS)-aware network- cloud service composition, including system model and problem formulation for network-cloud service composition and our proposal of an efficient algorithm to solve this problem. We also report the experimental results for evaluating the performance of the proposed algorithm in this chapter.
