1. A computer implemented method to adjust integration of composed applications of distributed components, the method comprising: identifying a composed on-demand application for a user, the composed on-demand application comprising a plurality of application components deployed on a plurality of data centers; deriving, using a processor, virtual geo-distances between the plurality of application components based on physical locations of the plurality of data centers, wherein the virtual geo-distances between the plurality of application components are indicative for corresponding data latency associated with distances between the physical locations of the plurality of data centers; and based on the derived virtual geo-distances, automatically adjusting configuration of the plurality of application components to optimize behavior of the composed on-demand application according to the corresponding data latency, wherein the automatic adjustment of the configuration comprising: influencing discovery and exposition of services at the composed on-demand application, based on the derived virtual geo-distances between the plurality of application components.
