As a kickoff to Google IO, Google announced the release of Google App Engine 1.5.0. The addition of long running instances has added a new level of control over the kinds of applications that can be run on the infrastructure. Pull Queues, another new feature, allow instances to request tasks. (In the past, these same tasks were relegated to individual instances.) A high replication datastore has been designated as the default. Later this year, Google will officially change the status of Google App Engine, making it an official Google product. At an estimated $9/month, using Google App Engine shouldn't be an expensive proposition.
