When to use The Littlest JupyterHub#
This page is a brief guide to determining whether to use The Littlest JupyterHub (TLJH) or Zero to JupyterHub for Kubernetes (Z2JH). Many of these ideas were first laid out in a blog post announcing TLJH.
**The Littlest JupyterHub (TLJH)** is an opinionated and pre-configured distribution to deploy a JupyterHub on a single machine (in the cloud or on your own hardware). It is designed to be a more lightweight and maintainable solution for use-cases where size, scalability, and cost-savings are not a huge concern.
**Zero to JupyterHub on Kubernetes** allows you to deploy JupyterHub on Kubernetes. This allows JupyterHub to scale to many thousands of users, to flexibly grow/shrink the size of resources it needs, and to use container technology in administering user sessions.
When to use TLJH vs. Z2JH#
The choice between TLJH and Z2JH ultimately comes down to only a few questions:
Do you want your hub and all users to live on a single, larger machine vs. spreading users on a cluster of smaller machines that are scaled up or down?
If you can use a single machine, we recommend The Littlest JupyterHub.
If you wish to use multiple machines, we recommend Zero to JupyterHub for Kubernetes.
Do you need to use container technology?
If no, we recommend The Littlest JupyterHub.
If yes, we recommend Zero to JupyterHub for Kubernetes.
