The Serverless Framework is an open-source tool that simplifies the development and deployment of serverless applications. It allows developers to build applications without managing the underlying infrastructure, enabling them to focus on writing code. The framework supports various cloud providers, including AWS Lambda, Azure Functions, and Google Cloud Functions. With the Serverless Framework, developers can define their application's architecture using simple configuration files. This approach streamlines the process of deploying functions, managing resources, and monitoring performance. By leveraging serverless computing, organizations can reduce costs and improve scalability while maintaining flexibility in their development workflows.
