EC2 RDS Resilient Three-Tier Baseline

Build a resilient three-tier architecture with Auto Scaling EC2 instances, Application Load Balancer health checks, and RDS Multi-AZ with read replicas — a high-value SAP-C02 resilience and DR scenario.

EC2 RDS Resilient Three-Tier Baseline - Platform Engineering Hands-On Lab Icon

Lab Overview

Deploy a complete resilient three-tier web architecture on AWS. Create security groups enforcing least-privilege tier isolation. Launch an RDS instance with Multi-AZ for automatic failover. Configure an Auto Scaling group behind an Application Load Balancer with health checks. Validate resilience by simulating instance and AZ failures — exactly the kind of architecture scenario tested in SAP-C02 Domain 2 and Domain 3.
