CloudFormation, Load Balancers & Auto Scaling Explained | AWS Cloud Practitioner | Day 18

Welcome to Day 18 of the AWS Builder Challenge 2026, a structured 21-day learning series designed to help you prepare for the AWS Certified Cloud Practitioner (CLF-C02) certification. Today's session brings together some of the most important AWS concepts used in modern cloud architectures: Infrastructure as Code, Elastic Load Balancing, Auto Scaling, Single Sign-On, Identity Federation, and Multi-Account Governance. You'll learn how AWS CloudFormation automates infrastructure deployment, how different Elastic Load Balancers distribute traffic, how Auto Scaling automatically adjusts capacity based on demand, and how AWS Organizations, IAM Identity Center, Service Control Policies (SCPs), and AWS Control Tower help organizations securely manage multiple AWS accounts. We also complete a hands-on lab where we deploy infrastructure using AWS CloudFormation and place an Application Load Balancer in front of multiple EC2 instances.
