This article proposes a next generation ubiquitous converged infrastructure to support the cloud and MCC services of the future. This infrastructure facilitates the interconnection of DCs with fixed and mobile end users through a heterogeneous network integrating optical metro and wireless access network technologies. The proposed architecture will address the diverse bandwidth requirements of future cloud services by integrating advanced optical network technologies offering fine (sub-wavelength) switching granularity with state-of-the-art wireless Long Term Evolution (LTE) access network technology supporting end-user mobility through wireless backhauling. To support the IaaS paradigm as well as the diverse and deterministic QoS needs of future cloud and mobile cloud services, the proposed architecture adopts the concept of virtualization across the technology domains. The proposed virtual infrastructure (VI) planning is taking a holistic approach that considers jointly the presence of all network technology domains and the IT resources to offer globally optimal solutions in terms of specific objectives such as energy consumption and resource requirements. This holistic approach also ensures allocation of the required resources across all technology domains to support not only the volume of service requests, but also their specific characteristics such as mobility of end users. Our modeling results identify trends and tradeoffs relating to resource requirements and energy consumption levels of the infrastructure across the various technology domains that are directly associated, with the volume and nature of the services supported.
