An application deployment manager 8 associated with an associated Mobile Edge Computing server receives a notification (step 222) of a newly-attached terminal, and queries a database 60 (step 223) to identify any computing applications the terminal is associated with, and interrogates an application platform 12 and an update record 72 to determine whether the current version of each required service is currently hosted on the platform 12 (steps 225, 250). The application deployment manager 8 then retrieves any programme data not already hosted on the application management system (step 227) for installation ready for use by the terminal 2.
