The use of cloud computing is increasing in the field of high-energy physics (HEP). Both dedicated
and opportunistic cloud resources are delivering a growing fraction of the requirements of
large projects. The use of context-aware designs, such as those used in the mobile communication
industry, can improve our distributed systems and make them more responsive to changing
demands and dynamic resources. We show how context-aware service have been implemented
and their impact on the system. We describe our plans to add new context-aware capabilities in
the future.
