Cloud and hub usage

Cloud and hub usage#

This displays the usage of our cloud infrastructure to give an understanding of our infrastructure setup and the communities that use it.

Last updated: Jul 30, 2026

Data source

Raw data:

This data is pulled from these two sources:

  1. The list of our hubs and clusters is pulled from our infrastructure/ repository.

  2. The active users data stream produced by JupyterHub and exposed at metrics/. See this PR for the feature.

Active users#

Unique monthly active users for each cluster. Clusters roughly map onto member communities (several of which have several sub-communities and hubs underneath them).

Click the dropdown for a list of month-end unique MAU counts, and see the dropdown at the top of the page for the raw data.

Number of clusters and hubs we run#

Multiple hubs are often run on a single cluster (e.g. a community with many sub-communities, one hub per class at an institution, etc).

Active users per hub#

Active users broken down by each hub that we run. Gives an idea of whether we have many hubs with few users, vs. a few hubs with a ton of users.
