In this presentation, recorded at the recent Google I/O Conference, Martin Fowler and Rebecca Parsons of ThoughtWorks describe some of the applications they've developed for Google App Engine, including implementation of other languages, such as JRuby, on top of the App Engine for Java implementation.
They also present an initial framework for characterizing different kinds of clouds and examine how these characteristics will impact the adoption path for enterprises and the kinds of applications these enterprises will move to the cloud. Of particular interest here is the central role of Big Table in App Engine. Broad adoption of this platform could lead to lots of lightening striking at the dominant role relational data base systems currently enjoy.
