Cristian, In my case I am moving from OpenNebula to ACS.
ACS seems like a good compromise between being lightweight and capable. I am happy with Local Storage, it is true that it is a mount-point but I mount a LVM volume there, which can be a raid, multiple drives, etc. ACS does a good job with Local Storage VM migration (even if not live migration). For me local storage is best and then the fail tolerance can be provided at a higher level (k8s?, etc) But my use case is not public cloud, but rather in-house corporate private cloud.
