The CryoCloud is a JupyterHub built for NASA Cryosphere communities in partnership with the International Interactive Computing Collaboration 2i2c. Launched in October 2022, the CryoCloud cloud-computing projects aim to establish a curated interactive computing platform and develop Cryosphere community expertise in open-soured and cloud-based platforms. The intention is to transition NASA communities into the cloud while discovering the needs and overall best practices for making this transition. This documents the first CryoCloud JupyterBook. The book documents the content, training, and best practices for scientific cloud computing, collaboration, and open science built by the CryoCloud team.
