Serverless computing lets you run code without managing servers. AWS Lambda is the most popular serverless platform.

Key benefits: No server management, automatic scaling, pay per invocation, built-in fault tolerance.

Lambda supports Node.js, Python, Java, Go, and more. Each function gets up to 10GB memory and 15 minute execution time.

Common use cases: API endpoints, data processing, scheduled tasks, webhooks, file processing, real-time stream processing.

Triggers: API Gateway, S3 events, DynamoDB streams, CloudWatch scheduled events, SNS notifications.

Cold starts are the main challenge. Mitigate with provisioned concurrency and keeping functions warm.

Serverless is ideal for event-driven architectures. Combine with API Gateway for REST APIs and DynamoDB for storage.
