WCF NetTCP Binding Over Internet

Question

I have a question. I would like to serve a series of services made with WCF. The client that consumes the services is also .NET with WCF. I would like to have high speed of

Answer 1

Since you plan to use simple types and small data contracts, the binding you use is nearly irrelevant compared to the latency introduced by going over the Internet. So, the right answer is to use the one which is easiest to manage and the most secure.

I recommend that you host the app in IIS and use a wsHttpBinding and take all the manageability goodness that goes along with it. It will also happen to be interoperable, and while that is irrelevant today, it is just free, so why not?

And, please consider the granularity of your service. You know your customers better, but on the wide open Internet, stuff happens. Because the round trip time over the Internet is variable and impossible to control, it could take milliseconds or seconds or may not get there at all. So, you should take fewer trips with larger payloads if possible, and use all sorts of caching and async operations to make the app appear "fast".
