2 Discussion: See starter question in the minutes

Overview:

• Main services offered by the AF.
• Scale: amount resources and number of users.
• What triggered the deployment of the AF? Were users demanding Jupyter/Dask/Scale-out etc.?
• What has been the adoption by users? Is the usage increasing over time?
• Do you only support interactive analysis? If not, how does non-interactive analysis look like?
• Can the AF be used via a terminal/batch?

Metrics

• How do you measure how many (active) users are using the facility?

• What other user metrics do you measure? Real-time or historical time series?

• What KPI do you consider to define success from the point of view of AF operations?

• How do you monitor storage (XCache or other) usage and performance?

• Number of users?

Software distribution

• How are the client software libraries made available to the users

• To what extent, and how, can users customize their software stack (e.g. versions of Coffea and dependencies)?

• To what extent do you provide support of the client software side? E.g. having one or few software distributions that are "guaranteed" to work?
