Secure APIs with Authorization
Create APIs with robust authentication and authorization using AWS serverless technologies.
Overview
Secure APIs are essential for protecting sensitive data and ensuring that only authorized users or systems can access specific resources. AWS serverless technologies provide robust authentication and authorization capabilities that can be implemented without managing complex infrastructure. This approach allows you to focus on your business logic while leveraging AWS's security expertise.
Architecture
Secure API Architecture
A reference architecture for secure APIs showing the flow from authentication through API Gateway to Lambda functions with proper security controls.
This architecture provides a comprehensive security model for APIs. Amazon Cognito handles user authentication and identity management. API Gateway uses authorizers to validate tokens and control access to endpoints. Lambda functions implement business logic with fine-grained permissions through IAM roles. Secrets Manager securely stores and manages sensitive credentials needed by the application.
Pricing Calculation
Small Scale (1,000 users, 500K API calls/month)
| Service | Usage | Monthly Cost |
|---|---|---|
| Cognito | 1,000 MAU | $0.00 (Free tier) |
| API Gateway | 500,000 requests | $1.75 |
| Lambda | 500,000 invocations (128MB, avg 200ms) | $0.21 |
| Lambda Authorizer | 500,000 invocations (128MB, avg 100ms) | $0.11 |
| Secrets Manager | 3 secrets | $1.20 |
| CloudWatch Logs | 5 GB | $2.50 |
| Total | $5.77 |
