Who	Question	Answer
JCH	How many VMs do they manage, and how many people are required to manage the OpenStack infrastructure?
JCH	What led to the decision to choose OpenStack at that time?
JCH	Are the VMs billed or is the service free? If they are billed, on what basis? And is this billing automated?
JCH	How is the lifecycle of the VMs managed?
MBA	Use of micro-segmentation (east-west isolation)? If yes, what technology?
MBA	Are VM deployments automated? (cf Aria Operations with automated processes).
MBA	Update cycle (security, updates, new features, etc.)? The level of complexity for carrying out these updates?
MBA	Is their VM architecture solely based on OpenStack or do they operate in a hybrid mode (multiple types of hypervisors)?
MBA	What is their level of satisfaction with the product, support, and OpenStack strategy in the long term?
MBA	What is the operational load (depending on the scope) to manage and maintain the OpenStack infrastructure?
MBA	Do they have a cost estimate for their OpenStack infrastructure (OPEX)?
MBA	Regarding security audits, is it possible to trace information about actions on VMs, hypervisors, etc.?
MDO	Ceph and HPC? How is Ceph used in the context of computation on HPC clusters?
MDO	How are Kubernetes clusters generated on OpenStack?
MDO	Average hardware lifetime?
MDO	How many people are required to manage CERN Ceph clusters?
LBO	Do their OpenStack clusters rely on homogeneous hardware?
LBO	Are they often confronted with solutions that do not support OpenStack as a hypervisor layer?
RFA	How do they manage OpenStack updates?
RFA	How do they manage bare metal deployment?
RFA	Redundant network infrastructure?
