Embodiments of the present invention provide an approach for mapping requirements (e.g., functional and/or non-functional requirements) to components and/or policies of a system topology in a networked computing environment (e.g., a cloud computing environment). In a typical embodiment, a set of functional requirements is mapped to a set of components. A set of dependencies between the set of functional requirements is then indentified so that a set of interrelationships between the set of components may be identified. A set of non-functional requirements is then mapped to a set of policies that are then applied to the set of components. Based on the set of components, the set of interrelationships, and the set of policies, a system topology is generated. Upon implementation of the system topology, runtime metrics may be collected as feedback that is utilized for refinement of the system topology, as well as a system topology deployed in the future.
