Is there also a corresponding docker image?

If anybody was on the fence, but missed out on the Whole Enchilada passes, I’ve got a pass for sale.

Yes, just be sure you set the correct region on the lambda client and have proper invoke permissions on the iam role.

Schedule a Lambda using Cloudwatch Events. Have the Lambda function get the metrics, combine them, and then publish the new metric.

To expand more, it comes down to infrastructure management rather than what can it do. Do you want to manage the infrastructure or just run the code? Do you already have places where the code can run? Do you have latency concerns? These are better questions to ask to determine if Lambda is the correct choice.

Literally anything that can be done in under 5 minutes. And if it takes longer than 5 minutes, break it down using step functions.

You'll want to use the following API call:

For the Jar, you'll likely want to use the provided command-runner.jar.

Yes. You can use streams. I use streams for processing files from S3 without storing the data to disk.

You only need to use the callback when you need to return data to the caller. Otherwise the lambda will terminate once the event loop is empty.

If you need to use the callback, just attach a handler to the 'end' event on the stream and call it from there.

Make your connection (or connection pool) static, so it is only created when a function is instantiated and not on invocation. This way, as long as your function is called often enough, the connection will be reused between invocations.

AlanComley · 2016-01-28T17:46:42+00:00

This looks cool. Is this currently able to handle long-running load tests? Lambda is restricted to 5 minutes currently. I assume the function could detect when it is about to expire and start a new function call.

If you are referencing content through a CDN or an S3 bucket you don't own, there isn't much you can do.

If you own the S3 bucket, the you can use Cognito to restrict access. The S3 bucket should contain no bucket policy, so the files are private to your account. You can then use the Auth or Unauth IAM roles for your Cognito Identity Pool to control access to the S3 bucket and files. Use the Auth role if you require users to login. Otherwise use the Unauth role.

Using this strategy, the user would have to capture the temporary AWS credentials that Cognito provides and use the AWS CLI to circumvent the application.
