I coincidentally have a meeting with some sales reps and an engineer about their cloud infrastructure this afternoon. Anyone have questions they'd like asked? I'm trying to figure out if we can get our enterprise customers to trust their private cloud tech and then deploy our products within it. It's a long shot, but I have trouble saying no to sales people before there's money involved.
