Description
At the University of Cambridge, hardware resources provided via the IRIS collaboration form an essential part in the data processing activity for two ESA science missions. For the Gaia mission, the core photometric processing recently migrated entirely to cloud infrastructure provided through IRIS. Using Apache Spark based distributed processing to characterize and calibrate the photometry and low-resolution spectra and generate the photometric and spectral data products for the upcoming Gaia DR4 catalogue. For the upcoming PLATO mission, aiming to discover earth-like exoplanets around solar-like stars, IRIS cloud resources are being used as the platform for the Exoplanet Analysis System which will be a key element of the on-ground processing.
