SQS Worker with Serverless ⚡️

Experimental Serverless Amazon SQS Worker with AWS Lambda.

Update: Please see Serverless Analytics for a more realistic setup using Amazon Kinesis Streams to process your data and events. You can read more about the Kinesis and Lambda connection at Serverless Analytics with Amazon Kinesis and AWS Lambda. This was only intended as an April Fools' project …

Setup

• SQS Queue with your messages
• SNS Topic to handle CloudWatch Alarms
• DynamoDB table to persist configuration
• CloudWatch Schedule as cron replacement
• Three (scale, worker, process) AWS Lambda functions

Workflow

• CloudWatch Alarms on queue length post to SNS
• SNS Topic triggers scale Lambda function
• Function scale updates configuration in DynamoDB
• CloudWatch Schedule invokes worker every x minute(s)
• Function worker reads configuration from DynamoDB
• Function worker invokes process function(s)

Add noise to SQS

You should have some data in your queue to test this setup. Use wrk to send messages to SQS, but make sure to enable anonymous access to sendMessage for your queue first!
