Organizing Large Web Service

[Spam Catcher]

Hi all,

How do you all organize your large web services?

I have a service which needs to cover multiple components. Do you build one
asmx file for all the functions. Multiple ASMX files - grouping by
functionality? Or have do you go the document route - in which the details
are in the XML, and the web service routes it to the appropriate backend?

Some of the components need "high" performance, and I need usability, so
I'm hoping to stay away from the document-centric model.

Any ideas?

Thanks!

One of the good things about webservices is that you can offset load between
servers easily based on functional requirement. Given the opportunity, its
easy to treat a set of services as a component and dedicate hardware to it,
of course if they need to call other webservices in a chain this can impact
performance. There is though no reason why you can't have lots of asmx file
locally utilising each others services though, nor is there really any
reason why you can't have one asmx file with lots of methods in it.

I tend to have lost of asmx file with related methods encapsulated and
offset these to other servers if the load in any single asmx method might
cause bottlenecks.

Most often, I would think in terms of functionality, which may or many not
correspond to the actual assemblies. Each service (page) should focus on a
particular set of methods that fit a particular type of functionality. If
you think of each page as a service (it is), then you are fine.

You do not have to line up services with "documents" in another application.
In fact, in most cases, that is a detrimental way to design your services,
as you are thinking UI rather than service.

Any ideas how I can reduce the number of web references? For example if an
application needs access to multiple ASMX files - it'll become tedious to
add all those references all the time?

[George Ter-Saakov]

You can have multiple WebMethods in single asmx file...
That is usually how it's done...

So you need to add only one reference... Like here for example
http://cardone.com/test/service1.asmx

I know that - but what happens when you have 100's of methods?

That's my problem.

[George Ter-Saakov]

Nothing happens :)
You just have a 100's methods...

Usually in your asmx file you have only declarations. As soon as method
called you route it to your internal classes... Which can be in different
files.

So your asmx file is not big at all. Like 4 lines per method.

PS: Of course I do not know what kind of web service you doing but usually
it's not suppose to be 100s methods. Rarely you need to expose all your
business to outside world.
May be you can expose one method "DoTheDew" that takes one string (or
generic class ) as a parameter.
That string suppose to be XML which is parsed out and routed to
appropriately. Something like
----IN--------------------
<BOD>
<Action>CreateOrders</Action>
<ActionDetails>..........</ActionDetails>
</BOD>

----OUT---------------
<BOD>
<Status>Success</Status>
<ErrorMessage></ErrorMessage>
<ResponseDetails>..........</ResponseDetails>
</BOD>
