Today at its latest Campfire One event, Google announced major updates to Google App Engine, their scalable cloud computing platform for web applications. App Engine developers will soon be able to create web-scale applications using standard Java APIs, and will be able to create AJAX components using Google's Web Toolkit. Other major features include cron support for scheduling tasks, tools for securely accessing and importing data, and a new Google development plugin for the Eclipse IDE.
Google continues to churn out releases to its platform-as-a-service Google App Engine API. Since the beginning of the year, there have been new releases every 4-6 weeks. The latest is out with focus on bringing parity between its Java and Python releases, a couple of new APIs that allow writing applications that monitor incoming live data and read/write files, and some task queue/cron updates.
