Enterprise Service Bus - definisjon og bruksmåter

This report defines the term Enterprise Service Bus (ESB) as a software architecture facilitating application integration using message routing. A typical ESB product supports many different functions, such as monitoring and controlling message routing between services, distribution/version control of services, and often a lot of other functionality as well (for example protocol conversion, security). We investigate one specific product, WSO2, and discuss the functionality it offers and how it potentially could be used. This product was chosen as an example because it is easy to obtain, and not because it necessarily is better than other products on the market. This report does not suggest which ESB to choose, rather it discusses the desired functionality and standards support that should be considered when choosing a product in the future.
