DLL that you call from within a web page hosted in IIS

I have an algorithm, written in MS C++ that I'm going to move to the cloud. But I don't know a lot about cloud applications. The plan is that I just work on my algorithmic code, and somebody else who is versed in cloud stuff will hook it up. It was suggested that I modify my code into "a DLL that you call from within a web page hosted in IIS". Can someone tell me what I might need to know about this? Do you think I need to know anything about web or IIS to do this? If I just format my code as a DLL that could be called by another C++ program (a test harness) - then should I be able to hand off that DLL to somebody else to stitch into the usage by "a web page hosted by IIS" ? I would want to supply a DLL (not source code) with a published API that others can put "in the cloud". Wondering if I need to know about web and IIS...

OK, thanks. Just wanted someone else to say "all you need to do is supply the DLL and api" -- which is what I was hoping....

You need to create COM/COM+ DLL to use in your webpage.
For beginner tutorial on COM is here.

Oh, I'm not going to get into the COM nightmare -- I'll produce a DLL and hope others on the project can hook it into the web.

Or, am I wrong, is COM not a total nightmare?

You can go through the tutorial link provided above(here).You can understand it easily.
I don't think a normal dll can be called in web page.
COM dlls are language independent dll, can also be called from any non-scripting/scripting languages like java script/vb script ect...
