Re: [soa-rm-ra] Cloud, IBM and orchestration

[Ken Laskey <klaskey@mitre.org>]

Michael,

I always questioned the "global" choreography view because in real life you never know what everyone is doing with everyone else.  Moreover, you have no need to know.  But most of life is a choreography with bits of orchestration thrown in.  My concern is while orchestration works well for the well-defined local aspects, I think "global" orchestration on too large a scale (e.g., the who is responsible for feeding Moscow problem) is equally futile.  However, it is very appealing because it gives the illusion of control.

Another interesting (IMO) note from the Cloud Expo was that IBM (and many followed) talked exclusively orchestration as a form of collective efforts and denied orchestration on the basis it did not work right. If you recall, I said (for the last 2 years) that global choreography (in WS CDL sense) is not suitable for services and represent and anti-pattern.

I hope, we will create a 'pragmatic practical SOA RAF' guide and the comment above is my 1 p. into this.
