Hi Michael,

Hi,
I have a problem understanding the intention of SCA. Of course I know,
what I can do with it, but I do not see why and when I should use it.
In my opinion it seems to be well-suited for building software
applications that consists of several components.
But what about business processes and SCA? I have 10 existing systems
that provide their capability by means of web services. Now I want to
realize a business processes requiring those capabilities. Here I need
user interfaces to interact with the process and so on. Sure, I can use
bpel as implementation for a component.
But why should I do this? I have Webservices, I have BPEL-engines. I
don't see the advantages.
And if I want to have components I can use Java. Sure, SCA supports
several languages. But SCA does not support .NET as one of the most
important big players.
Maybe you can help me, why SOA needs SCA :) Isn't IBM the only
enterprise using SCA? Haven't seen SCA engines from Oracle/BEA, SAP etc.
Some interesting articles:
- SOA is dead; long live Model-Driven SOA (January 26, 2009) [0]
- Oracle Tuxedo 10gr3 (January 21, 2009): [1]
"Certainly the most exciting part of these releases is the support for
the Service Component Architecture (SCA) in SALT 10gR3."
- SAP: [2]
SAP forms part of the OASIS SCA-BPEL TC.
- Relevance of the Service Component Architecture Standard to a Business
Process Expert (an old article from SAP): [3]
