actually, i see to much revolutionary technology. i read some pages
quickly about this one, and they didn't say it is anything brand new.
so to those, who think it is another way of thinking, i say very good,
man! we need many useful aspects of seeing a problem, but not all
aspects need a new programming language or environment or such. my
example is always Ada, and the way how they incorporated all OO
aspects into a previously existing language with extending what was
already there. you want SOA? then think that way, and keep using
your current programming tool as long as it conforms enough.

SOA is just a new label for the good old distributed computing.
The only new thing is that they now try to use available protocols to
transfer the requests instead of a specific protocol like CORBA.
The most common protocol is TCP/IP as protocol and XML as
data format.
The basic disadvantage is that SOA uses a stateless environment
and thus implies more management tasks to assure a fixed data flow.

all that much about SAO, but it looks to me that it will gel in well with
the application that need performance as one of its criteria. and also we
may need to invest on the development of some additional tools to manage
and maintain these services.

The data has to be converted to XML, send, converted back from XML
then the same for the response again.
Thus SOA via XML has a lot of overhead in the interface stubs, which
is not so good if you really need the performance.

SOA stands for Service Oriented Architecture and it does not imply that the
data has to be sent via XML. Indeed XML is a common mode of transporting
data but that is an implementation detail.

I think it's MS' second attempt at getting everythoneto adopt Web Services.
Their initial Web Services push was viewed as too MS-centric.
