Here is the video of a quick talk I gave two weeks ago at OW2Con 2012 dealing with Petals Enterprise Service Bus.
He gives some background about what is Petals, how it can be used, why it is a distributed runtime, what is really new in the last version and finally what is planned in the next version.
I already spent many time explaining what we have in mind to push Petals in the cloud and this will be a reality in the next months as we are currently working on that exiting feature. More information soon, for real this time!
