Google App Engine – now supporting Java

Prior to this they have only supported Python, a language with a far more limited following. Here’s the rundown:

  • Supports JDK 1.6.
  • Free for limited use, no ability to pay for heavier use yet
  • Can access data behind the firewall through Secure Data Connect
  • Supports cron and data import ability
  • Uses BigTable (key/value pairs) for storage, so can’t use JDBC. Instead Java Data Objects (JDO) or the Java Persistence API (JPA)
  • Hasn’t yet passed Sun certification tests
  • Can support other languages that compile to bytecode and run on the JVM, like Ruby and JavaScript

Sounds like another interesting offering in the cloud computing arena.
