IT cloud services are expected to have a compound annual growth rate (CAGR) of almost 25% each year from 2013 to 2017 (IDC forecast). In order to keep up with this rapid evolution, it is essential for service and network providers to have efficient mechanisms and tools that simplify resource provisioning and management while minimizing capital and operational expenditures. In fact, cloud service is evolving from predefined to on-demand and user-driven provisioning. Because legacy networks have many limitations, cloud service environments should be significantly scalable, reliable and cost effective. Software as a service (SaaS), Platform as a service (PaaS) and Infrastructure as a service (IaaS) are increasingly considered to achieve these cloud environment objectives. However, there are several challenges that need to be considered when defining solutions for such public cloud environment. Among them, we can list definition and validation of mechanisms that enable service level agreement (SLA)-based resource allocation, resource scaling; resource availability; resource monitoring and recovery to support dynamic, efficient and on-demand resource provisioning over public cloud where both providers and customers are satisfied. This research program addresses very challenging issues related to resource provisioning and management in distributed virtualized communication environments. New mechanisms and tools will be developed to enable flexible and efficient networks and services provisioning and management within these environments. New mathematical models and algorithms will be developed that aim at satisfying multiple objectives of virtualized communication environments. New mechanisms will be also developed that integrate configuration, provisioning and optimization of resources through federation of virtualized communication environments. This research program will provide novel approaches that ease the migration towards open and interoperable communication environments while satisfying both providers and customer expectations.
