Data User Elements (DUE) is an important program within the
European Space Agency (ESA). The program is conducted at the ESA
Centre for Earth Observation in Frascati, Italy. DUE uses
satellites to collect valuable data about the current state of
the planet. The program is about demonstrating the usefulness of
Earth Observation products and services to end users worldwide.
DUE provides this data to scientists, governmental agencies, and
private organizations around the world. The data is used for a
myriad of purposes, including monitoring the environment,
improving the accuracy of weather reporting, and assisting
disaster relief agencies. Although much of DUE’s work is done by
satellites, some of the program’s data storage and computing
infrastructure is built on Amazon Web Services (AWS). DUE uses
Amazon’s scalable Web storage, Amazon Simple Storage Service
(Amazon S3), to house and retrieve its images and other end-user
products. To manage its files within Amazon S3, the program
utilizes a third-party tool b
