JupyterHub is the best way to serve Jupyter notebook for multiple users. Because JupyterHub manages a separate Jupyter environment for each user, it can be used in a class of students, a corporate data science group, or a scientific research group. It is a multi-user Hub that spawns, manages, and proxies multiple instances of the single-user Jupyter notebook server.
Distributions#JupyterHub can be used in a collaborative environment by both small (0-100 users) and large teams (more than 100 users) such as a class of students, corporate data science group or scientific research group. It has two main distributions which are developed to serve the needs of each of these teams respectively.
The Littlest JupyterHub distribution is suitable if you need a small number of users (1-100) and a single server with a simple environment.
Zero to JupyterHub with Kubernetes allows you to deploy dynamic servers on the cloud if you need even more users. This distribution runs JupyterHub on top of Kubernetes.
Note
It is important to evaluate these distributions before you can continue with the configuration of JupyterHub.
Subsystems#JupyterHub is made up of four subsystems:
a Hub (tornado process) that is the heart of JupyterHub
a configurable http proxy (node-http-proxy) that receives the requests from the client’s browser
multiple single-user Jupyter notebook servers (Python/IPython/tornado) that are monitored by Spawners
an authentication class that manages how users can access the system
Additionally, optional configurations can be added through a config.py file and manage users kernels on an admin panel. A simplification of the whole system is displayed in the figure below:
JupyterHub performs the following functions:
The Hub launches a proxy
The proxy forwards all requests to the Hub by default
The Hub handles user login and spawns single-user servers on demand
The Hub configures the proxy to forward URL prefixes to the single-user notebook servers
For convenient administration of the Hub, its users, and services, JupyterHub also provides a REST API.
The JupyterHub team and Project Jupyter value our community, and JupyterHub follows the Jupyter Community Guides.
