In a virtualized cloud-based server environment, quality of service is assured by optimising the placement of service components according to the geographical location (eg. GPS latitude/longitude) of consumers 211 via a topological model 213 of candidate hosts to which bounding conditions 217 (eg. delay, bandwidth, storage) are applied in order to select a particular host 219 from an ordered list 218. The consumers position and velocity are periodically reevaluated in order to select hosts dynamically. |
