Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for determining a first cost and a second cost associated with a virtual memory page accessed during execution of an application, the first cost being associated with a first memory type, and the second cost being associated with a second memory type in a hybrid memory system, comparing the first cost and the second cost to provide a comparison result, determining a current location of the virtual memory page, the current location including one of the first memory type and the second memory type, and selectively migrating the virtual memory page from the current location based on the comparison result and the current location.
