I’m working on a .net portal which would be having lots of concurrent users. so scalability,performance need to be addressed in the design and architecture. We plan to use load balancing in the application.

Keeping this in mind,what would be the best way of communicating between IIS web server(hosting aspx,aspx.cs files) and application server (hosting .net assemblies like business logic and data access layer)? Should it be .net remoting or soap web service?or is there any other approach?

Thanks.

  1. Is there another approach? Yes – don’t distribute your objects. The most scalable approach is to NOT to distribute your objects away from each other. Ask yourself, why do you want to deploy one flavor of code to an ‘app server’ while another flavor of code goes to a ‘web server’? The communication that goes on between those two layers, if they are distributed, will be much much much much (etc etc) more expensive than a local call.

    With today’s 64-bit servers, with all of that memory, and the hot CPUs, and with ASP.NET’s superior memory management, why not put your business logic and DAL on the same physical machine as the ASPX files? Why not?

    If you need to scale, add more servers. Simple.

    There are good reasons, of course, to distribute. The most common good reasons have to do with domains of ownership – along several axes: security management, or even budget and control. In other words, to take the latter case, if team is responsible for running the business logic and a separate team is responsible for building and running the web layer -then it may make sense to distribute those two things to allow independence of management. Most of the good reasons for distributing computer code, have their origins in the structures of the human organizations using or developing the code.

    There is no good technical reason why a web page should not run on the same CPU, sharing the same CLR VM and memory heap, as the database access layer.

    Regardless what you do with distribution, it would be unwise to architect your system with less-than-formal interfaces defining the connections between the layers. If you keep formal interfaces, then it should be no problem for you to measure the perf and efficiency of a distributed approach versus a co-located approach.
