WADI is an acronym of 'WADI Application Distribution Infrastructure'.
WADI started life as a solution to the problems surrounding the distribution of state in clustered web tiers. It has evolved into a more generalised distributed state and service framework.
WADI's aim is to resolve many of the problems of dealing with state in a cluster.
