Abstract:
The offers on cloud computing infrastructure have focused on providing computing and storage resources, and consider the network mostly as a required add-on and not truly as a resource itself. However, the need to have more robust solutions is becoming clearer. This paper argues that cloud infrastructure services will evolve and allow the definition of complete infrastructures that comprise both computing and network resources, referred to as Virtual Infrastructures (VI). The VI embedding problem is addressed through joint virtualization of computing and network resources. An Integer Linear Programming (ILP) formulation is presented and different embedding strategies are proposed: load balancing, combining the load balancing of physical resources with minimal bandwidth consumption; green, reducing the energy consumption of the infrastructure; dynamic, combining both load balancing and green strategies depending on the substrate state. To enable real-time optimization, a heuristic approach is also proposed.
