February 2021 Summaries

Serverless computing is a cloud-computing execution model where the cloud provider runs the server and dynamically manages machine resources based on actual consumption, allowing developers to focus on building products without worrying about infrastructure. Lumigo, a company, adopted 100% serverless technologies in its CI/CD pipeline, implementing a supercharged flow with guiding principles such as personal AWS environments, a serverless-first approach, and the developer's responsibility from A to Z. The company uses tools like GitHub, Pytest, Flake8, Serverless, CircleCI, CodeCov, Snyk, and Lumigo for its development workflow, which includes planning, coding, testing, releasing, and monitoring. With a mix of Kanban and Scrum methodologies, automated testing, and continuous deployment, Lumigo's serverless development flow enables the company to quickly release features and ensure high quality while minimizing errors.

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.
