Understanding AWS Load Balancer Types and Traffic Routing

Modern cloud applications require robust distribution of traffic to ensure high availability, fault tolerance, and seamless scaling. Understanding how to route web traffic effectively is a core skill for anyone building on AWS. This text-based course guides you through the fundamental mechanics of cloud load balancing, helping you confidently choose and implement the right architecture for your workloads. You will transition from understanding basic traffic distribution concepts to analyzing complex routing scenarios for real-world applications. By reading through clear explanations and practical architectural scenarios, you will learn how to optimize performance and prevent single points of failure. What you'll learn: - Understand the core concepts of load balancing, health checks, and high availability - Compare the features and use cases of Application Load Balancers (ALB) and Network Load Balancers (NLB) - Configure routing rules, target groups, and path-based routing for microservices - Apply security best practices, including SSL/TLS termination and basic security group integration - Integrate load balancers with Auto Scaling groups to handle fluctuating traffic demands - Monitor load balancer metrics to troubleshoot latency and traffic distribution issues This course begins with foundational networking and load balancing definitions, establishing a solid baseline before moving into detailed comparisons of AWS Elastic Load Balancing options. You will then explore practical configuration strategies, traffic routing rules, and modern infrastructure integration patterns. This course is designed for beginner cloud practitioners, aspiring DevOps engineers, and system administrators who want to build a strong foundation in AWS traffic management. No prior load balancing experience is required, though a basic familiarity with cloud concepts is helpful.
