Lightning Talk: Controlling Home Directory Costs (with User Empathy) on the Cloud With `jupyterhub-home-nfs` - Yuvi P, 2i2c User home directories on JupyterHubs deployed in cloud providers has been a pain point for both end users and administrators. Administrators feel the pain of cloud costs for home directory storage (sometimes higher than compute!). No user wants to receive an email saying "well, this code you copy pasted downloaded 3TB of netcdf files into your home directory, and now we have used up our entire team's cloud budget for the next 2 years" (true story). The `jupyterhub-home-nfs` open source project is a JupyterHub native, cloud agnostic solution to these problems. Administrators can do per user limits, tune performance, report on usage and make cloud cost conscious choices around overprovisioning. It providers users empathetic *guardrails* to prevent them from overuse, rather than punitive *gates* that zap them after the fact. In this short talk, we will: 1. Describe the core of the problem, and how it manifests for users and admins. 2. Review current solutions and their limitations 3. Introduce `jupyterhub-home-nfs` and how it solves moves the solution space forward 4. Demo how this looks like for an end user 5. Talk about future direction, and opportunities for collaboration
