Two new developments are now available for the Google App Engine. Google is offering a Cloud Playground so developers can experiment with code without having to install the Cloud Engine software development kit. "Essentially, it's like Codecademy for the cloud, Google App Engine for idiots, or cloud-enabled applications development for newbies," John Koetsier writes. Appscale's ScaleSafe is an open-source backup that serves as a backup platform-as-a-service. "The companies that provide services in these markets represent a new reality that demands apps be built faster than ever before," Alex Williams writes.
