Collaborating at a distance: Operations centres, tools, and trends

Successful operation of the LHC and its experiments is crucial to the future of the worldwide high-energy physics program. Remote operations and monitoring centres have been established for the CMS experiment in several locations around the world. The development of remote centres began with the LHC@FNAL ROC and has evolved into a unified approach with distributed centres that are collectively referred to as CMS Centres Worldwide. An overview of the development of remote centres for CMS will be presented, along with a synopsis of collaborative tools that are used in these centres today and trends in the development of remote operations capabilities for high-energy physics.
