Event driven architectures (EDA) will come in the following years more to the front in distributed applications and their architectures. Some think they are the next step after SOA, others have the idea that the 2 (reference) architectures complements. Eitherway, in todays distributed applications some concepts of EDA are already used, although mostly the defined/used software delivery cycles don’t position them very explicitly in a good structured quality generating delivery process. Contemporary SOA is becoming a mature technique and a new standard in enterprise architectures. The possibilities are that EDA undergoes the same and delivers some extra or other quality characteristics than contemporary SOA. It can bring the continuous seek to unification intra and inter applications and/or enterprises to a new level. What EDA certainly shall do is bring our designs closer to an inherent attribute of nature: send and move on.
