AWS Load Balancing Fundamentals for Scalable Applications

As web traffic grows, keeping your applications online and responsive requires efficient traffic distribution. Understanding how to route requests across multiple servers is a fundamental skill for any cloud practitioner or developer working in modern environments. This text-based course guides you through the core concepts of AWS Elastic Load Balancing. You will transition from understanding basic traffic routing to designing fault-tolerant, highly available cloud systems using different load balancer types. What you'll learn: - Understand foundational networking and load balancing terminology, including listeners, target groups, and routing algorithms. - Compare and select the right load balancer type—Application, Network, or Gateway—for your specific application needs. - Configure health checks to automatically detect unhealthy targets and ensure traffic is only sent to functional instances. - Apply secure traffic routing principles by integrating SSL/TLS certificates for HTTPS termination. - Practice monitoring load balancer performance using modern observability tools, access logs, and metrics. - Explore Infrastructure-as-Code patterns for deploying load balancers programmatically. The course starts with essential terminology and the basic mechanics of traffic distribution before moving into step-by-step written guides for configuring each load balancer type. You will wrap up by learning how to monitor traffic patterns and automate your setup using modern cloud practices. This course is designed for beginners new to cloud infrastructure, system administration, or backend development, with no prior load balancing experience required.
