  :: when I seprate the layers fysiclally on different machines why do this? this will kill performance and scalability. or maybe you just misunderstood .net remoting.

  :::: when I seprate the layers fysiclally on different machines ::why do this? this will kill performance and scalability. or maybe you just misunderstood .net remoting. I don't mean separate them all (3 machines in this case just for the fun).. But i saw some winforms starterskit//sample-apps where they try to run the DAL as a service, even a webservice, so you can seperate it for the rest.. I'm not sure If this will have any advantages, that was my question. I didn't used remoting for so far...

I'm not sure If this will have any advantages One advantage of a webservice is that you can usually expose it to the external world. So, theoretically your app could run inside the co. firewall and outside the co. firewall (assuming correct DMZ setup, etc). If remote access is a requirement and it cannot be only a web app and you cannot implement a VPN then this type of architecture MIGHT be appealing. However, webservices are SLOW, so you would have to accept the performance hit in return for a wider range of access. I would suggest though doing a web app or VPN before doing this type of architecture.

  You said "webservices are SLOW". Would remoting be any faster? If not, what could be the best solution?
  Thanks much.

  You can put your BLL in the client and DAL in the server and use either web service or remoting to call your DAL from your client.

  What do BLL and DA stand for in full? Thanks.

  BLL = Business Logic Layer
  DAL = Data Access Layer (or Data Abstraction Layer)
