AWS Production Environment - CTM Tier 4 implements a hardened, multi-AZ architecture spanning DMZ, application, and data tiers across ap-southeast-1 with Route 53, CloudFront, Shield, and WAF protecting inbound traffic. ECS Fargate tasks run in isolated private subnets across AZ-1 and AZ-2, with role-based access control, RDS PostgreSQL multi-AZ failover, and KMS encryption at rest securing the data tier. GuardDuty, Network Firewall, Inspector, and Security Hub provide continuous threat detection and vulnerability scanning, while CloudTrail, VPC Flow Logs, and X-Ray enable full audit and observability. CloudWatch, SNS, EventBridge, and Lambda orchestrate automated incident response and remediation workflows, with CodePipeline and Terraform IaC ensuring repeatable, drift-free deployments.
