• deploy the service function in the online application exchange;
• identify a first domain event requesting access to the service function from a user;
• call, with a wrapper function, the service function in the online application exchange, in response to the first domain event;
• record, with a wrapper function executed on top of the service function, a metric associated with the service function and a return parameter;
