The document discusses open data on AWS. It provides an overview of how shared data on the cloud can accelerate research. AWS cares about open data because its customers supply and use data shared on AWS. Sharing data in the cloud allows data users to spend more time analyzing data rather than acquiring it. The AWS Public Datasets registry allows finding satellite imagery, elevation data, transportation data and more that are shared publicly. Examples show environmental monitoring, flood forecasting, and optimizing ship navigation using open data on AWS.
