An Always On capability in version 1.4.0 enables reservation of application instances to ensure live instances of an application at all times. This addresses latency issues and is an alternative to on-demand application instances, which are provided when requests come in.
App Engine 1.4.0 is "huge," said Matt Mastracci, CTO of App Engine user Gripe. The company provides complaint resolution services for mobile and Web users. "For us, the big [features] are High Replication Datastore, which means we never go down for maintenance," and the Always On capability, he said. Always On prevents users from ever having to wait for an instance of the application.
Google App Engine made its debut in April 2008 and hosts about 150,000 active applications per week. "We're now seeing about 1 billion page views per day," Lynch said.
