1. What about support for cron-like periodic events? Maybe something like cron.yaml in Elastic Beanstalk, but serverless.
2. Does Java support means, that it will be possible to write lambdas in any JVM hosted language, like for example Clojure?
2. Yep. Initially, you'll have to include the Clojure runtime as a library in your ZIP file, so it will look to Lambda like a Java function. Then assuming there's interest, we'll promote it to a first-class experience in the console and API as a language of its own at a later date.
