Infrastructure as a Service (IaaS) clouds promise unlimited raw computing resources on-demand. However, the performance and granularity of these resources can vary widely between providers. Cloud computing users, such as Web developers, can benefit from a service which automatically maps performance non-functional requirements to these resources. The authors propose a SOA API, in which users provide a cloud application model and get back possible resource allocations in an IaaS provider. The solution emphasizes the assurance of Quality of Service (QoS) metrics embedded in the application model. An initial mapping is done based on heuristics, and then the application performance is monitored to provide scaling suggestions.
