An incident occurred in the past week where an infinite loop in AWS incurred a massive bill. Essentially, every time a file was uploaded to S3 file storage, it triggered a Lambda function that would re-upload a new file back to S3, which would then re-trigger the Lambda function again. This process would repeat infinitely. As everything is serverless, all services are able to scale up indefinitely, including the bill. Watch the video to learn more and see how the problem was discovered and stopped as well as some solutions to prevent this from happening again.
