Scope of a SCA assembly [message #499638]

Hi,

I am currently trying to class SCA with the entire SOA topic and to put
it into an entire SOA development process.

Assuming, I have a big picture showing all my services and their
dependencies that are required to fulfill my business requirements. Now,
I want to realize this service-oriented architecture.

Which parts of this service landscape are now transferred into one SCA
assembly? Is every service a SCA assembly? Or is the entire landscape a
SCA assembly?

Greetings

Mike

I think you are misjudging SCA.
SCA has several facets. One of them is the implementation of services.
Just like web services.

Another one is related to integration.
Another one is related to combining services to create a higher-value
service (yes, just like BPEL, under another shape).

But clearly, one facet SCA does not have is SOA governance.
When you have your big picture, you can't see SCA.
Some of the services in your picture may be part of an SCA application,
but that's it. SCA won't help you to organize or classify your SOA
architecture. Or if it does, it's up to you to find how.

Regards,

Vincent.
