So being an international company, we didn't want to be limited to having to VPN into one location. We built it around the idea that, anywhere you are, at any time, with your certain set of security protocols, we'll give you access. The data's going to pretty much stay where it is and not leave. So that's our definition of our internal facing cloud. We have accomplished that through a variety of technologies, but it's been scaling quite well. We've put thousands of workers on it.

How hard was it to get right?

HireRight has used Citrix for a lot of years and because of that we knew going in what does and doesn't work. One of the things we don't really care about is the network speed coming in. We've architected the solution to handle up to 300 milliseconds.

But it took a lot of mapping of business functions and groups, putting people into compartmental boxes -- these guys should see this slice, these guys should see that slice of . So I'd say 50% of it is knowing what people need and getting them correctly allocated, while the other 50% is understanding the limitations of the technology and planning accordingly.

One piece of advice for companies getting into it is the devil is in the details. You'll see everything from disk storms on storage arrays to problems getting applications published correctly and questions about how you lock it down correctly. All those were exercises we spent years working on. So we're actually proud of this particular endeavor because it's kind of the culmination of a lot of years of effort.
