AWS Lambda adds CORS support and removes preview signup requirement

CORS and Browser JavaScript Support for AWS Lambda

AWS Lambda now supports CORS, making it easier to call Lambda functions from browser JavaScript code. The default hosted package of the AWS SDK for JavaScript in the Browser now also includes the AWS Lambda APIs by default — check out Working with Services in the Browser.

No more preview signups!

AWS Lambda has dropped the signup requirement – the preview is now open to anyone with an AWS account. You can go immediately to the AWS Lambda console and begin using AWS Lambda. We hope this makes it even easier for customers to try out the service, including using the interactive editor and test functionality to write and run Lambda functions directly from a browser.
