AWS Elastic Load Balancing for High Availability

In today's cloud-driven world, application downtime means lost revenue and frustrated users. Building resilient systems starts with understanding how to distribute incoming traffic effectively across multiple servers. This text-based course guides you through the fundamental principles of high availability using AWS Elastic Load Balancing (ELB). You will learn how to set up, configure, and manage load balancers to ensure your applications remain online and responsive even during traffic surges or server failures. What you'll learn: - Understand core high availability concepts and how load balancing prevents single points of failure - Configure EC2 instances to act as secure, functional web servers - Create and manage target groups to route traffic efficiently to healthy instances - Set up security groups to enforce the principle of least privilege for your load balancer and servers - Deploy an Application Load Balancer and configure health checks to monitor instance status You will start with key cloud architecture terminology and foundational networking concepts. From there, you will progress through written, step-by-step configuration scenarios, learning how to link EC2 instances, security groups, and target groups into a unified, resilient system. This course is designed for beginner cloud administrators, aspiring DevOps engineers, and IT professionals new to cloud infrastructure. No prior cloud configuration experience is required to begin.
