Google Introduces Cloud Functions
- Cloud Pub/Sub – any asynchronous Pub/Sub event
- Cloud Storage - Object Change notifications
- HTTP Invocation – synchronous invocation through HTTP
- Debug/Direct Invocation – using the CLI to develop/debug Cloud Functions
We asked Google what Cloud Functions can do:
The function has full access to the internet so you can call out to any 3rd party API, however you'll have to maintain your own auth keys etc for these external services.
Google did not want to comment on future development, so we do not know if they will add support for other languages. But it is likely they will.
