Serverless Architectures

Build scalable apps without managing servers. Master AWS Lambda, API Gateway, and DynamoDB for event-driven architectures.

Serverless allows developers to focus on code, not infrastructure. This course teaches you to build event-driven applications using AWS Lambda. You will trigger functions from HTTP requests via API Gateway, file uploads to S3, and database changes in DynamoDB. Learn to manage state with Step Functions and observe your distributed applications using X-Ray. This architecture minimizes operational overhead and scales to zero cost when idle.
