Amazon EC2 Auto Scaling, Instance Currently supported options are: proxy [String] the URL to proxy requests through; agent [http.Agent, https.Agent] the Agent object to perform HTTP requests with. Be aware that the Lambda function owner can update the function operation without CloudFormation being notified. I have the Bucket name as a parameter so this stack can be replicated elsewhere by passing a separate bucket name for creation. In this tutorial, you create a Lambda function and configure a trigger for Amazon Simple Storage Service (Amazon S3). However, you can enable Capacity We need to select the destination for our event notifications. Project instances in a warm pool. function_name - (Required) Name of the Lambda function whose resource policy you are updating You specify the Amazon Resource Name (ARN) value of these destinations in the notification configuration. The basic storage unit in S3 is known as a Bucket, aptly named as its just a cloud object container where you can dump anything into it literally. Easy with Amazon EC2 Auto Scaling, Building a Backup System for Scaled Instances using Lambda and Amazon EC2 Run AWS S3 supports event notifications, where you can set up notifications on specific events on an s3 bucket. Privacy Policy and Terms of Use. So we have successfully configured S3 event notifications for an SQS topic.
