When you ve chosen more than a single process to use to host your software, you have to decide how you ll communicate between them. Marshaling information between processes takes on many forms and can traverse many boundary types. One thing is constant, and that is that marshaling is expensive. There will always be a performance hit on your application, whether you re moving pieces of a system into different physical tiers or across processes on the same physical tier. Marshaling can occur across application domains within a process, across processes on the same machine, across machines within a LAN, or across machines distributed on the Internet. Different types of communication work best for different scenarios. Performance is not always the most important consideration when you re deciding how to communicate between processes. Most often, the decision to introduce another physical tier has already been made (a prerequisite for needing to select a communication technology), and other nonfunctional requirements, such as the need to use a pool of database connections, are larger considerations than performance (see 1 for several examples of these decisions). Communication and marshaling breaks down into two facets: What am I sending out of process (or out of the application domain), and how am I sending it What you re sending out of process can be a SOAP-formatted document, binary data, or a Message Queuing (MSMQ) message. How you ll send it involves a protocol, be it HTTP HTTPS, named pipes, or TCP , . We summarize the options in Table 8-2. With Web Services, what you re sending is always a SOAP message. Many people have the misconception that SOAP messages must always be sent via HTTP or HTTPS, but the SOAP specification intentionally leaves the question of protocol open. This means that SOAP messages can be send via TCP Simple Mail Transfer Protocol (SMTP), MSMQ, or a custom , protocol. HTTP and HTTPS are still the most common way to send Web Service requests. Remoting breaks the questions of how and what into two extensible layers of abstraction: channels and messages. The Remoting infrastructure is specifically designed to enable someone to plug into his own channel (protocol) and provide his own message format (what s getting passed over the protocol). Remoting ships with implementations of both channels and formatters; HTTP IPC, and TCP for channels, and SOAP and binary for message formats. ,

Web Services Can be exposed directly via configuration from COM+; otherwise, expose via IIS. Remoting Component Services should be exposed to clients using Remoting via IIS when using HTTP . To use TCP a custom , listener must be created and installed as an NT Service. Deploy a configuration file specifying URL to use to reach exposed type into the root of the web application. Must use HTTP as a channel, but any formatter can be chosen. .NET includes SOAP and binary formatters. N/A DCOM and Interop A DCOM proxy can be generated, and a .NET client can use it via an interop assembly. Custom interop is used internally by COM+ to communicate between managed and unmanaged stacks. N/A

You can use the COM SOAP stack to expose these as Web Services. You could also use ASMX and an interop assembly to expose them via IIS.
Use an interop assembly to expose functionality, or use vendor provided interop assemblies, such as the Office interop assemblies from Microsoft.
You can write a custom listener process that accepts requests from a TCP channel or via HTTP You can also program it to expect binary or SOAP messages over your chosen channel. . These choices are independent. It s only when you re hosting a remoted component within ASP .NET that you re limited in these choices, as you are bound to the HTTP channel. However, this channel can still be used to send binary or SOAP messages. We ll take a look at all of these scenarios in the sections that follow. Remote objects can also be used to pass messages across application domains within a managed process. This is what Remoting is most highly optimized to accomplish, and is what Microsoft says is the best reason to adopt Remoting. See 6 and 9 for a discussion of some of the issues relating to Remoting versus Web Services (which is really a debate of RPC versus Service Oriented Architecture, or SOA). With the introduction of the Windows Communication Foundation (WCF), Microsoft is moving this concept of an extensible layer of transport and messaging into all out-of-process calls that are done in the operating system (see 9 for a preview of WCF). This is why WCF is called the unified out-of-process call stack. Today with WCF, Web Services requests can get passed via MSMQ as easily as they are via HTTP There are really a lot of valid combi. nations.
