Classic 3-Tier Web AppAWS Architecture Template

ALB-fronted web and app tiers on EC2 with RDS persistence and Redis caching inside a VPC.

Why this architecture works

  • Separating web and app tiers limits blast radius and lets each tier scale independently
  • ElastiCache absorbs read-heavy traffic so RDS stays sized for writes, not cache misses
  • Database credentials live in Secrets Manager, never in AMIs or environment files
  • ALB health checks plus CloudWatch alarms detect unhealthy instances before users do

From template to running infrastructure

  1. Open this template in the CloudForge visual designer (free account, no credit card).
  2. Customize resources, names, and connections on the drag-and-drop canvas — or ask Vani, the AI architect, to adapt it.
  3. Generate production-ready Terraform or CloudFormation in one click.
  4. Review the plan diff and security scan, then deploy with human approval.
