Here’s the original question:

Hi Udi,

This is Kumar, i am new to .NET and related technologies. Actually i am designing an application with few a components like a Socket Server(a service) which received input from payment terminal for loyalty application, which should communicate with Web Services deployed in an IIS application server, then the web services should communicate with an Oracle Database.

What are the patterns and best practices to use for the communication between the socket server and application server, and how do I scale for multiple clients in socketserver, and what are the security things that i need to consider.

Should i need to use .NET Remoting instead Web Services for my application server layer, and which is best for my socket server?

Thank you for your support.

Kumar
