proIO GmbH
I am CEO of proIO GmbH based in Frankfurt am Main, Germany. We are using Cloudstack for over 3 years now in production to provide a high performance public cloud (www.megona.de). 1,5 years ago we migrated all vms from shared storage to local storage to use SSD disks only connected directly to the hypervsiors to get a maximum of IOPS.
