The selection of Cloud providers, whose offers best fit the requirements of a particular application, is a complex issue due to the heterogeneity of the Cloud services, resources, technology and service levels offered by the several providers.

We describe its implementation inside Cloud Agency to broker the proposals that best fit user's needs.
