An approach to affinity-based network configuration is disclosed. In one approach, an apparatus for configuring a network based on affinity is described. The apparatus includes a set of business rules describing the order of importance of a plurality applications, an affinity analysis module that receives the set of business rules and a plurality of application requests and detects affinities between the application requests and an infrastructure of the network based on the set of business rules, an affinity computation module coupled to the affinity analysis module that determines a new network configuration based on the detected affinities, and a network management module that configures the network based on the new network configuration.
