"The automation and provisioning of network services to create the best user experience." (Forrester)

🌁Software Engineering: Service Choreography (Definitions)

"A way of aggregating services to business processes. In contrast to orchestration, choreography does not compose services to a new service that has central control over the whole process. Instead, it defines rules and policies that enable different services to collaborate to form a business process. Each service involved in the process sees and contributes only a part of it." (Nicolai M Josuttis, "SOA in Practice", 2007)

"An a priori global and public model meant to capture all the interactions taking place for a given purpose among a number of participants." (Giorgio Bruno & Marcello La Rosa, "Collaboration Based on Web Services", 2008)

"Choreography is the message exchange behavior that a business exposes in order to participate in a business relationship based on electronic message exchanges." (Christoph Bussler, "Business-to-Business (B2B) Integration", 2009)

"An architectural style in which one or more components in a software system are event-driven and minimally coupled. 'Minimally coupled' means that the only relationship between the event producer and the event consumer is a one-way, “fire and forget” notification.
