Difference between web services & remoting?

1) Protocol :

 Webservice can be accessed over HTTP protocol . Remoting can be accessed over any protocol (including TCP, HTTP, SMTP etc)

2) Interoperability :

Webservices support interoperability across platforms, and are ideal for heterogeneous environments. Remoting requires the client be built using .NET, enforcing homogenous environment.

3) Ease of programming :

Webservice is easy to create and deploy . Remoting is complex to create

4) State Management :

Webservices are stateless . Remoting support for both stateful and stateless environments through Singleton and SingleCall objects
