Multiple choices in hybrid cloud connections
David is right, there's a strong networking component in hybrid cloud operation. But the cloud vendors haven't been slouches on this point. If you're concerned about accessing the cloud by private network and you're looking to a telco cloud provider, such as Verizon, CenturyLink or NTT, you may be in luck. They'l like to package their cloud services with a private line access. The public cloud providers, including Amazon with Direct Connect, and Microsoft Azure, with Express Route, get you off the Internet and onto a private line as soon as your workload can reach an Equinix data center. No question but you need to know the details of how it's going to work for you.
