AWS Application Load Balancing for Scalable EC2 Systems

As web traffic grows, keeping your applications online and responsive becomes a critical challenge. Understanding how to distribute network traffic effectively is the key to building reliable, fault-tolerant cloud architectures. This text-only course guides you through the process of setting up an AWS Application Load Balancer (ALB) to manage traffic across multiple EC2 instances. You will learn how to design a secure network environment, route requests efficiently, and ensure your applications remain highly available even during traffic spikes or server failures. What you'll learn: - Understand the core concepts of load balancing, high availability, and cloud network architecture. - Configure Virtual Private Cloud (VPC) subnets across multiple Availability Zones for redundancy. - Deploy and configure EC2 instances to run behind a load balancer. - Set up an Application Load Balancer (ALB) with target groups and routing rules. - Implement automated health checks to ensure traffic only goes to healthy instances. - Apply security best practices using security groups and modern traffic encryption principles. You will start by learning the fundamental terminology of cloud networking and load balancing. From there, you will progress through setting up your VPC, launching EC2 instances, and configuring the Application Load Balancer to distribute traffic. This course is designed for beginners in cloud computing, aspiring system administrators, and developers looking to understand AWS networking basics. No prior experience with load balancers is required. Start reading today to master the essentials of scalable cloud infrastructure.
