But still need to find a way to support lower layers of software infrastructure (e.g., hypervisor, storage) Buy support from a vendor (e.g., use of enterprise distros with “free” Linux).,Free!,Misconception: OpenStack is a Product,No, it is an open source codebase, managed by OpenStack Foundation Manages process around changes to the open sour
