The Need

The European Space Agency (ESA) shares earth observation (EO) data collected through its comprehensive fleet of satellites orbiting the Earth with the many communities that study and leverage the data for scientific, commercial and educational purposes. The fleet of satellites serve multiple missions including the SMOS mission to measure soil moisture and ocean salinity, the Aeolus mission to profile the earth's wind patterns, the Cryosat mission to measure polar sea ice thickness and changes in ice sheets and the Swarm mission to study the earth's magnetic field.

Scalable data storage

GTT Virtual Data Center solution stores and processes ESA’s more than 8PB of earth observation multi-mission satellite data.

Hybrid cloud infrastructure

ESA's hybrid cloud is based on the GTT Virtual Data Center (VDC) solution, stores and processes ESA's EO multi-mission satellite data. The GTT VDC private cloud also offers a "single-pane-of-glass" user interface fit for a multi-cloud environment by allowing portability to third-party public clouds.

Network integration

Integration of multiple internet and connectivity resources to allow users to view, retrieve and perform data tasks using various archives and tools.


Working with GTT and other institutional partners, ESA is offering the many communities engaged with long – and short-term earth surface data exploitation, the ability to access and process data in a practical and secure way for a wide range of scientific, commercial and general interest purposes.”
