Architecture

[Tom]

Hello,

I have a Windows form application that currently uses a database local to
the machine it is running on. We are planning on setting this application
up for a multi-user environment, so I would like to change to a 3-tier
architecture application for scalability:

1. My Client
|
2. My Business Logic Server (The client connects here)
|
3. My database server

We may also create another web form client in the future, and I would also
like that to connect to the business logic server as well.

My question is, what type of communication do you guys recommend between the
exist client and the business logic server?

1. If I use .NET remoting, can an ASP .NET page easily utilize the .NET
remoting code if I create an additional web form in the future?

2. If I setup the logic server to provide web services to clients, I have
heard that web services don't support transactions across multiple database
servers, so if I can't use web services, what should I use?

Any help is greatly appreciated. Thanks.

I personally would not use .NET remoting if you are thinking of the future. I
would use web services or better yet WCF.

Any code you write in a web service can be transactional.
