Services are increasingly provided by cloud computing systems. Such services are often accessed while on the move. If the distance between the user and the service is getting large, quality-of-experience, in particular for interactive services, deteriorates. To counter this, the provisioning location of the service should be as close to the user as possible. This paper describes the concept of follow-me cloud, according to which services are migrating in unison with the user’s movements. The key components required for such integrated user mobility/service mobility management are introduced and mappings to an OpenFlow-based implementation are described.
