Cloud Brokers enable interoperability and portability of applications across multiple Cloud Providers. On the other hand, incoming Cloud Providers start to support more and more unbundled Cloud Instances offerings. Thus, consumers may set up at their will the quantity of CPU, network bandwidth and memory or hard disk capacities their Cloud Instances will have. These facts enable the standardization of interoperable Cloud Instance configurations. In this paper, CompatibleOne is presented as an approach to bring Cloud Computing as a commodity. For this, the requirements to make of a product a commodity have been identified and have been mapped into the CompatibleOne architecture components. Our approach shows the practical feasibility of bringing Cloud Computing as a commodity.
