Building Scalable Websites with Elastic Load Balancing and Auto Scaling

Modern websites must handle sudden spikes in traffic without slowing down or crashing. Understanding how to distribute incoming web traffic and automatically scale your infrastructure is a fundamental skill for any cloud practitioner.\n\nThis text-based course guides you through the core principles of high availability and load balancing. You will transition from hosting a single server to deploying a self-healing, scalable web architecture that automatically adapts to user demand.\n\nWhat you'll learn:\n- Understand foundational cloud scalability concepts, including horizontal vs. vertical scaling and high-availability design.\n- Configure secure-by-default security groups to isolate your application servers and load balancers.\n- Create reusable launch templates to define the baseline configuration for EC2 instances.\n- Set up an Elastic Load Balancer to distribute incoming traffic efficiently across multiple targets.\n- Configure Auto Scaling groups with modern target tracking policies and health checks to handle fluctuating traffic automatically.\n- Analyze traffic flow and verify system redundancy using structured configuration exercises.\n\nYou will start with essential terminology and the theory of cloud elasticity before moving on to step-by-step configuration guides. Through written explanations and clear architectural walkthroughs, you will learn how to connect and secure every component of a modern scalable system.\n\nThis course is designed for beginners who want to learn cloud infrastructure basics, with no prior scaling experience required.\n\nStart building resilient, production-ready web architectures today.
