The Reactive Manifesto Authored by Jonas Boner, Dave Farley, Roland Kuhn And Martin Thompson. The Manifesto was created in response to companies trying to cope with changes in the software landscape, what happened was multiple groups of people independently developing similar patterns for solving similar problems. Aspects of a Reactive System were individually recognized by these groups, and The Reactive Manifesto is trying to bring these common ideas into a single unified set of principles.
