Automatic modeling of virtual resources with sizing recommendations

A method includes accessing a database comprising a respective non-linear scalability model for each of a plurality of physical resources and each of a plurality of virtual resources in a virtualization environment. The method also includes generating a respective capacity consumption model for each of the plurality of virtual resources based on the non-linear scalability models. The method further includes determining a deviation from a predetermined threshold range in the respective capacity consumption model for a first virtual resource in the plurality of virtual resources. The method additionally includes determining a slope of the respective capacity consumption model for the first virtual resource, and determining a sizing recommendation for components of the first virtual resource based on the slope and the deviation. The method also includes modifying at least one of the components of the first virtual resource based on the sizing recommendation.
