Fast Resource Co-provisioning for Time Critical Application Based on Networked Infrastructures

Resource provisioning is a key step in the deployment of applications onto clouds. When some datacenter is not accessible or some part of the infrastructure is crashed, the provisioning mechanism is therefore essential for these applications to recover quickly from sudden failures, especially for time critical applications. However, most current solutions focus on the cloud provider's hardware to achieve the fast provisioning of cloud resources. This paper proposes a co-provisioning mechanism to partition the customer's cloud resource requests while preserving their connectivity. This mechanism uses a brokering approach that is totally transparent to both the customer and the cloud provider, specifically considering the network topology. We carry out experiments on an NIaaS (networked infrastructure-as-a-service) platform, called ExoGENI. Experimental results and data analysis show that this mechanism is feasible and can dramatically improve the speed of resource provisioning.
