.NET Forum / ASP.NET / Web Services / February 2006.NET Remoting vs. Web Services
Any comments on .NET Remotinv vs. Web Services? Which would you choose? Thanks. Depends what I needed to do: if I needed to talk to a web-service, I'd choose a web-service! (etc) OK, being a bit more serious: remoting can be a pain; it demands incestuous knowledge between the client and server (even if it is only an interface in a shared assembly) - however, since it is generally used with binary transports, it is quicker, and allows convenient use of e.g. marshal-by-ref instances, proper tree serialization (instead of the light-weight xml structure etc), and a few other things. I would also recommend reading up on the proposed WCF details (part of WinFX and formerly known as Indigo) - this provides an alternative to remoting for talking between apps (e.g. services) in a schema-based way (similar to WSDL for web-services). Marc Thanks for the thoughts, I think? I have a showdown meeting to attend and I actually prefer web-services. > Depends what I needed to do: if I needed to talk to a web-service, I'd > choose a web-service!

Also note that the two are not necessarily mutually exclusive, although you would be introducing complexity by using both in tandem. Example comparitors: * Must it support non-.Net clients? * Must it support 1.1 clients? * Do we expect it to manage all security (authentication / encryption / etc) for us? * Do we need to be able to talk to different servers *at the same time* * What performance profile do we need? (paired with data throughput) * Do we need marshal-by-ref instances? (proxies held at the client that forward invoked methods to the server silently) * How complex is the data we are transporting - is it simple data, or complex object-graphs? * Must it work through firewalls? * Must it work via intermediaries? The list goes on... Marc It's actually pretty simple. The "component" needs to authenticate users to active directory. However, a proposal was made to separate authentication components on an application server (which I opose that too). So basically there is an LDAP component on an application server that receives calls from a remoting object on another application server that is called by the web server in the DMZ. I think it's a bit too much. So now they are making the argument that every application from this point must reference the remoting object to authenticate users instead of a web service on the server closest to the active directory server. Hope you understand what was just described, cause I'm not certain I understand it.

If your new component isn't going to be released for a little while the best answer is WCF (Windows Communication Foundation, formerly codenamed Indigo)... read this guide to get started with WCF - it is the future of distributed computing on the Windows platform. http://msdn.microsoft.com/msdnmag/issues/06/02/WindowsCommunicationFoundation/de fault.aspx Good luck!
