I share your sarcasm, Steve. Aspects embedding is an OO approach, not SO one. However, here is, at least, one way of setting a 'liability insurance' on the 3rd...

Hi I have to do a project for the class, suppose we're going to architect a sales department based on SOA. First of all, I have derived some composite services...
I suggest you ask your advisor to provide a definition of the terms "interface", "contract", and "description". There are no standard definition files that...
... Khoshnevis, if you are so much of a hurray then you might want to try the open source tools from www.pi4tech.org and generate the WSDL and even the Java...

Registries have very little capacity to store metadata. For example, it's difficult to store in a registry why I should use a particular service, how I should...
Now we get to the hard part, which is addressing the differences between secure software and security infrastructure. I believe your question is referring only...
Shared infrastructure... interesting. What about a manufacturer having 50 plants all over the world distributing their products to large retailers such as Home...
I share your sarcasm, Steve. Aspects embedding is an OO approach, not SO one. I agree but, aspects in terms of interceptors is not an OO approach. Filters,...
How come "new" software architectures are beginning to look like advances in hardware architecture made back when RISC processors were the hot, new thing? That...
I'm with you on that definition, I completely agree that security should be part of the infrastructure (almost ether like) between services as much as it is...
The solution is remote integration that integrates 50 disparate ERPs in each distributor site. ESB is best way to go as of today. No, there's a much easier...
Standardized infrastructure is probably the better way of putting it, rather than shared infrastructure, although it's not a big stretch to go from one to the...

... Should we consider firmware ESBs low level plumbing? I think we should. That's just one step away from considering software ESBs as low level plumbing....
Specifically regarding the examples you mentioned, yes. The way I've tried to draw a line between infrastructure and applications is to look at the domain of...
Having 50 ERPs doesn't have to mean 50 data centres, its relatively normal to reduce the number of data centres well below the number of instances (as an...
Ahhh the vision of "one ERP" there is another angle here which is "if it ain't broke don't fix it". The cost of doing an ERP rationalisation strategy can be...
I would say that "security infrastructure" is a "utility " service. Security is very much the service in spite of the question it answers. BTW, before getting...

Great point Michael. One of the things I usually point out is that you have to consider things from a consumer's perspective. Security is a great example....
