Declarative Cloud Resource Provisioning Using OCCI Models

Abstract

Great competition in providing cloud services has built a huge diversity in ways to manage the rented computing resources. This diversity has led to the provider lock-in problem, i.e., binding the customer to one provider. Moreover, the increasing need for quick and easy infrastructure provisioning requires for an automated and parallel provisioning process, as it is a cumbersome process when done manually. To tackle these needs, we propose a standard conform cloud resource provisioning process which is able to deploy declarative models based on the Open Cloud Computing Interface (OCCI) standard. Therefore, a provisioning plan is generated, defining the resource provisioning order, followed by a systematic execution of it. In order to show the feasibility of this approach, we implemented a prototype and discuss it with the help of an example topology.
