What Is JupyterHub?

JupyterHub allows you to create a multi-user Hub that spawns, manages, and proxies multiple instances of the single-user Jupyter notebook server.

JupyterHub can offer notebook servers to a class of students, a corporate data science workgroup, a scientific research project, or a high-performance computing group.

There are 3 main actors make up JupyterHub:

• Multi-user Hub (tornado process).
• Configurable http proxy (node-http-proxy).
• Multiple single-user Jupyter notebook servers (Python/Jupyter/tornado).

Roughly, this is JupyterHub works:

• Hub launches a proxy.
• The Proxy forwards all requests to Hub by default.
• Hub handles login and spawns single-user servers on demand.
• Hub configures proxy to forward URL prefixes to the single-user notebook servers.
• JupyterHub also provides a REST API for administration of the Hub and its users.

The diagram below shows you the high level architecture of a JupyterHub system.
