While the initial comments all look good, it seems everyone needs a bit of reality. I would love to see this actually work, but let's analyze this article:
1. "..over 4000 customers have chosen Cisco ACI" - yet my account team canNOT provide one reference customer in production.
2. "...excited to announce our plans to extend ACI into the public cloud domain" - no commitment on date. This looks, sounds, and feels like a response market announcements. High on hype, low on value.
3. "Today, ACI supports multiple hypervisors, bare metal servers, and Linux containers on premise" - that's a generous statement if you have the right hardware. How is Cisco going to decouple the requirements they've presented to our DC in a cloud environment?

Look, I'm all for this being real, but let's hold the fist bumping until something more solid than this vaporous marketing article comes to light.
