cloud computing environments

Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.

To demonstrate the practicality of two proposed model, research works are focused on as follows: O-Marketplace Model, after analyzing the limitations of existing cloud service delivery methods, a multi-cloud service delivery method is proposed to overcome these limitations, and a promising multi-cloud marketplace model is built up; Composable Application Model, we first build up its concept and its description method, then the experimentation is conducted by transform into TOSCA specification to evaluate the feasibility of the proposed multi-cloud application model.

Software-defined networking aims to change the inflexible state networking, by breaking vertical integration, separating the network’s control logic from the underlying routers and switches, promoting (logical) centralization of network control, and introducing the ability to program the network. Consequently, SDN is an important key for resolving aforementioned difficulties.
