The Lumigo team has created a free command-line tool called the Lumigo CLI to automate manual tasks in serverless technologies on AWS, such as Lambda, EventBridge, and SQS. The tool includes commands for right-sizing Lambda memory settings, tailing events captured by these services, replaying messages from an SQS dead-letter queue, switching between AWS profiles, and many more. These commands are designed to help developers focus on adding business value with serverless technologies rather than spending time on manual tasks. By using the Lumigo CLI, developers can streamline their workflow and improve the efficiency of their serverless applications.
