A repository stores a contract between a service consumer and a service provider that provides a service, the contract specifying a service-level objective associated with a service to be applied for the service consumer. An enforcement device is configured according to the contract, where the configuring causes the enforcement device to perform enforcement of the service-level objective in a connection between the service consumer and the service provider, the connection allowing the service consumer to access the service in response to the enforcement device confirming that the service consumer is associated with the contract.
