ALB High Availability with Path-Based Routing and Auto Scaling
Build a production-grade multi-tier ALB with path-based routing to multiple ASG backends, cross-zone load balancing, connection draining, health checks, and CloudWatch monitoring — the SAP-C02 high-availability networking pattern.
Lab Overview
Deploy a highly available multi-tier web architecture using an Application Load Balancer with path-based routing. Create dual target groups with custom health checks, launch independent auto scaling groups across two availability zones, configure a single ALB to route traffic based on URL path, and implement advanced features including connection draining and cross-zone load balancing. Test failover scenarios, enable access logging to S3, and build a CloudWatch observability dashboard tracking request counts, healthy host counts, 5xx errors, and target response time — core SAP-C02 Domain 1 (Design Resilient Architectures) patterns.
