Overview
The Serverless Framework is an open-source CLI tool that helps developers build and deploy serverless applications on cloud platforms like AWS, Azure, Google Cloud, and more. In a serverless architecture, the cloud provider automatically provisions and manages the infrastructure, allowing developers to focus solely on writing code. Serverless applications are composed of small, stateless functions that are triggered by events, such as HTTP requests or database updates. These functions are run on-demand, and developers only pay for the compute resources consumed during execution. Serverless eliminates the need to manage servers, making it ideal for event-driven and microservices applications.
Key Features:
- No Server Management: Cloud provider handles provisioning and scaling of servers.
- Event-Driven: Functions are triggered by specific events such as HTTP requests, file uploads, or database changes.
- Pay-Per-Use: Charges are based on actual usage, meaning you only pay for what you use.
- Automatic Scaling: Functions scale automatically to handle increased traffic.
- Multi-Cloud Support: Supports multiple cloud providers such as AWS Lambda, Google Cloud Functions, and Azure Functions.
Use Cases:
- Event-driven applications (e.g., file processing, messaging)
- Real-time data processing
- Lightweight microservices
- APIs and back-end services that require on-demand scaling
