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.

A commodity is a good that is uniform in quality between companies that
produce/sell it.
They are examples of commodities

Why should Cloud computing be a commodity?
3/11/20145 Intercloud 2014
■ Here are some reasons…
• Bring standardization to the Cloud
• Accelerate and make easier the trading of Cloud resources
• Enforce SLAs through monitoring
• Increase of technology adoption

■ Here are some reasons…
• Bring standardization to the Cloud
• Accelerate and make easier the trading of Cloud resources
• Enforce SLAs through monitoring

Issues preventing Cloud computing commoditization
3/11/20147 Intercloud 2014
■ Not standardized VM configuration
■ Unknown VM performance
■ Unilateral SLAs
• Cloud providers impose SLAs

Not standardized VM configurations

Unknown VM performance
3/11/20149 Intercloud 2014
■ Cloud performance differs in Cloud providers due to:
• Heterogeneity in hardware suppliers
• Different Cloud Management Software
