AWS Lambda lets developers run code without managing servers — known as serverless computing.

What is AWS Lambda?

AWS Lambda runs backend code in response to events, automatically managing infrastructure.

Benefits of Lambda

• No server management
• Scales automatically
• Pay only for what you use

Use Cases

• Real-time file processing
• Web applications backend
• IoT device data handling

Example: Node.js Lambda Function

exports.handler = async (event) => {
  console.log('Hello from Lambda');
  return 'Success';
};
