A computer-implemented method for placement of a plurality of application objects of an application within a network architecture is disclosed. The method includes generating during runtime of the application, an application topology model for the application, based on application metrics for the plurality of application objects. A resource topology model of a plurality of network nodes within the network architecture is generated based on resource metrics for the network nodes. A recommendation is generated for migrating an application object of the plurality of application objects to a network node of the plurality of network nodes using the application topology model and the resource topology model, the recommendation identifying the application object and the network node. The application object is migrated to the network node identified by the recommendation.
