AWS Application Load Balancers (ALBs) and ECS Fargate Clusters are integral to modern cloud-native architectures. ALBs are designed to handle advanced routing, distribute incoming traffic to multiple targets, and provide high availability and scalability. ECS Fargate, on the other hand, allows you to run containers without managing the underlying infrastructure, making it an ideal choice for microservices architecture.
