I think something like this would be invaluable. I think this particular area of technology is going to become very important for more and more people very quickly, and a nice road-map would be hugely useful. Also powerful would be if it were delivered in a wiki-style, collaborative environment so that it could be discussed and evolved by the community at large.

Jesse – LOL! That’s the reason why I didn’t go get another page and moved to a more structure tool (EA).

I’d hate to see the diagram the Software Complexist draws

Does a picture with a thousand words worth a million words?
Nice start, keep going

It’s great for a 1st draft, however the diagram seems to emcompass a variety of “lenses”.
for example there are conceptual temrs like Robustness, High Availability and ACID which describe the effects of a well designed system.
Then you have events. most notably are the Spoofing, Tampering, DoS.
Then there are infrastructure nodes like Database, HTTP, RPC.

there is an underlying picture you want to express. the picture can be viewed through any of these lenses, but trying to view the picture through all the lenses makes things fuzzy.

Another thought is what’s your target audience.
I still concider myself a novice at DDD and enterprise archicture. So just understanding the concepts and basic examples of messaging, uow, adaptive domain model provide tons of euraka moments. However details like spoofing, SaaS, multicore initialization, etc are just beyond me (or not applicable).

Then you have the more advanced audience who know about messaging, uow, and adaptive domain models. They want the details about preventing spoofing, how to utilize SaaS and multicore initialization, everying else is considered common knowledge.

again this is great material for a brain dump of the complexity of enterprise level systems. I think it now needs some refinement into what you want to communicate, and to whom.

Great!

I’ve always though that wikipedia should have a kind of “mind map” view, this is exactly what you’re proposing/showing.
I think the map should have a notion of importance. As you said “SOA is a tiny circle”…it should be more like a large town (using location map analogy) and why not having “Stive” a town with suburbs as spoofing, repudiation… etc.
So, yes, excellent idea, go ahead, and just highlight what are the strong concepts (large towns) and the main axes/relationships (highways)…just to clean it up.

Hello Udi

I like the idea, but from your picture I am not able to get an overview.
I suggest you use a tool like http://cayra.net/

Don’t publish this comment if you wish.
I’m wondering why did you distinguished S+S from SaaS. I personally don’t see any difference except from a marketing perspective.
