Using Application Load Balancer with AWS Lambda

Modern applications require scalable, serverless architectures to efficiently handle user requests. When integrated with an Application Load Balancer (ALB), AWS Lambda allows dynamic request routing without the need for traditional compute resources. This Cloud Lab focuses on building a serverless learning platform where instructors can upload learning materials for learners. The ALB routes traffic to two Lambda-based microservices, ensuring role-based access control.

In this Cloud Lab, you’ll explore how ALB interacts with Lambda functions and learn to configure listeners and target groups for specific endpoints. You’ll set up a Lambda function for instructors to manage learning materials and another for learners to access available content. The ALB will be configured to route requests based on predefined paths, ensuring proper request distribution. Additionally, you test the system by simulating requests to validate role-based access and security.

By the end of this Cloud Lab, you’ll gain hands-on experience integrating Lambda functions with ALB and designing a structured request-routing mechanism. You’ll understand how ALB enables serverless microservices and how role-based access can be implemented in a scalable learning platform.

The following is the high-level architecture diagram of the final infrastructure that you will build in this Cloud Lab:
