Serverless

Serverless is a framework and platform for building and running applications on AWS Lambda and other serverless cloud services. It lets developers define their application's functions, events, and infrastructure in a simple YAML file. With a single command, you can deploy the entire stack—code, AWS Lambda functions, and triggers—and have everything wired together automatically in the cloud. This removes the manual work of configuring cloud services, making it faster to go from code to a live application.

The tool includes a web dashboard that provides a central place to manage all your serverless applications, regardless of which AWS account or region they're in. This dashboard gives you instant metrics on usage, performance, and errors, and allows you to query across all Lambda invocations to troubleshoot specific requests. For teamwork, it offers secure ways to share secrets, environment variables, and AWS account access, and even lets you share and run test events for Lambda functions directly from the interface. Its ecosystem is extended by thousands of plugins that add new capabilities and integrations.

Serverless is built for developers and teams who want to adopt serverless architecture without getting bogged down in complex cloud configuration. It's particularly useful for building APIs, scheduled jobs, and event-driven applications. Large companies like Nordstrom and Expedia use it to streamline their development process, but it's also accessible for individual developers looking to deploy projects quickly and manage them efficiently.
