What is Serverless?

Serverless computing lets you run code without provisioning servers.

Benefits

  • No server management
  • Auto-scaling
  • Pay per execution
  • Reduced operational overhead

AWS Lambda

  • Event-driven compute
  • Multiple language support
  • Integration with AWS services
  • Sub-second billing

Common Patterns

API Backend

Lambda + API Gateway

Event Processing

Lambda + S3/SQS/SNS

Scheduled Tasks

Lambda + EventBridge

Considerations

  • Cold starts
  • Execution limits
  • State management
  • Debugging complexity

Conclusion

Serverless is ideal for event-driven, variable-load applications.
