The cloud paradigm

The Cloud Paradigm

NASA Earthdata is available from Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs) that are in the process of moving data holdings to a cloud platform. In the new paradigm, data storage (orange in the illustration) will migrate to the cloud (green) and DAAC-provided tools and services built on top of the data are co-located in the Earthdata Cloud.

As this data migration occurs, DAACs will have more information about how users can access data. For example, the Cloud Data page at PO.DAAC offers access to resources to help guide data users in discovering, accessing, and utilizing cloud data. During this transition, some data will continue to be available from the traditional on premise archive, while some data will also be available from and within the Earthdata Cloud.
