Serverless API (AWS Lambda)
Serverless architecture on AWS using Lambda functions for compute, API Gateway for HTTP routing, DynamoDB for NoSQL storage, and S3 for object storage.
This pattern eliminates server management, provides automatic scaling, and follows a pay-per-use pricing model. Ideal for event-driven workloads and APIs with variable traffic patterns.
