STFC supports a diverse set of Science Activities. These activities require a substantial “eInfrastructure” to manage, preserve, analyse and simulate their data. Such eInfrastructure includes both the physical infrastructure (HPC and HTC computing resource, disk and tape storage), and the software infrastructure needed to enable the data to be processed.
IRIS is the co-ordinating body for the provision of this eInfrastructure and is a collaboration between STFC, its eInfrastructure Providers and representatives from the Science Activities themselves.
More details of what IRIS is (and indeed what it isn’t) can be found under what is IRIS? and IRIS-FAQ.
