Currently, accessing global cloud services has its limitations in end-to-end quality of experience (QoE) due to the independent operation of cloud infrastructures and communication networks. The novel virtual network design approaches for resilient cloud services that are presented in this paper can realize end-to-end availability and latency guarantees by combining the control of network and cloud resources. We formulate design models as linear optimization problems to realize resilience either at the virtual or the physical layer. On the basis of extensive simulations, we analyze the effect on the overall performance when cost factors and influential parameters of the network virtualization environment are varied. We compare the proposed models in detail and show that they outperform prior approaches. Finally, we provide a discussion about the implementation and applicability of the proposed models.
