The document discusses the concept of cloud computing as a commodity, emphasizing the need for standardization to facilitate easier trading of cloud resources and enforce service level agreements (SLAs). It highlights the barriers to commoditization, such as the lack of standardized virtual machine configurations and performance variability among providers. The CompatibleOne platform is presented as a solution to these issues, demonstrating the technical feasibility of treating cloud infrastructure like other commodities.

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

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

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