How to Manage Application Load Balancer (ALB) with Terraform

In this article, we discuss how to manage AWS Application Load Balancer (ALB) using Terraform. ALB operates at layer 7 of the OSI model, allowing it to make routing decisions based on protocol, port, headers, method, and other attributes. We demonstrate how to configure an ALB with EC2 instances in separate target groups, integrate ALB with AWS Lambda functions, and use a Web Application Firewall (WAF) for enhanced security. The article also provides code examples and diagrams to illustrate the concepts discussed.
