Google adds memory to App Engine
Google's App Engine team have announced their first enhancements to App Engine for 2013 – High-Memory Instances and Mail Bounce Notifiers, now available in version 1.7.5 of the cloud platform. Users had wanted instances with more memory but without uprating the CPU; now the F4 and B4 instances can be used with 1GB, twice the previously available memory. A 1GB instance of the front end costs 16 cents more at $0.48 an hour than a 512MB instance ($0.32 an hour). Mail Bounce Notifications allow App Engine apps to be told when mail they have sent is not being delivered.
Google are also bringing online experimental support for the Java 7 runtime with its string-based switch statements, invokeDynamic support, "diamond" operators for generics and automated resource management. The notes for Java 7 remind users that Java 6 support will be removed in the future and it is worth checking existing apps with the new runtime.
Another experimental service being added is Google Cloud Endpoints, which make it simple to annotate applications and create OAuth 2.0 authenticated RESTful or RPC services. There are also updates to the Google Plugin for Eclipse, which add support for creating Android apps that talk to Google App Engine backends. Full details of all the changes are available in the release notes.
