Richards, Mark. «The Role of the Enterprise Service Bus (presentation)». Consultado el 4 de junio de 2009."I do not consider process choreography part of an ESB, if we consider an ESB as a high-speed messaging middleware. However, I do consider process choreography part of the ESB *platform*. Fortunately most ESB vendors separate out these major components into different products, but package them under a consolidated ESB offering. So, in the strictest sense of the word, no, I would not consider it as part of an ESB. It is a related capability."
