The initial setup of the solution is pretty straightforward. I don't think it's very complex, but I wouldn't call the implementation simple. If a person has knowledge of the solution, they shouldn't face any issues.

Some deployments take three months or more. Other deployments take less than a month. It depends on the complexity of the client's environment.

I wouldn't say the initial setup was straightforward, but it was well documented. Microsoft has good documentation. If you follow it, you have good chance of succeeding. If you deviate from it, you have good chances of never getting there.

Basically we had a planning phase. We laid it all out including how we were going to architect it, and then we deployed the gateway. It was a phased approach. We deployed the ATA lightweight gateway and each domain controller and did the port mirroring and all that.  

It took us, I think, from the planning phase, about three to five days going back and forth. The deployment phase that followed was maybe another three days. After that it was just tweaking, to make sure that we got to fine-tuning down.

We had two architects, two engineers, and then the help desk personnel, which maintains the solution. We used a network architect. We had a systems engineer and then we had the server techs. In total, at any given time, there were about four or five people helping.

The initial setup was complex. Without someone implementing it for us, we had to learn a lot of things on our own.
