vRA 7 introduced a number of new and very useful features such as unified blueprints, software components, event broker, and others. The event broker however has proven itself to be one of the most power new features we have seen in some time. How so you ask? Well if you have been working with vRA for any period of time you will remember the old way of triggering external workflow executions such as those run by vRO. If you have been using vRA for a really long time you will remember back before vRO when vRA wasn’t even vRA and run nothing but .Net workflows, but we won’t go back that far.
