"Production-ready" means the architecture keeps working when hardware or software fails, and gives complete observability when issues arise.
8 Pillars of Production-Ready AWS Architecture
- Network Foundation: VPC with public subnets (load balancers only) and private subnets (app servers & databases) spread across at least 2 Availability Zones. Tight security group rules.
- Self-Healing Compute: Auto Scaling Groups behind an Application Load Balancer. No single points of failure.
- Protected Data: Multi-AZ relational databases with automated backups and regular restoration drills. Encrypted storage at rest and in transit.
- Security & IAM: Least-privilege IAM roles, secrets managed via AWS Secrets Manager, separate AWS accounts for Dev/Staging/Prod, and MFA enforcement.
- Observability: Centralized logging (CloudWatch/OpenSearch), distributed tracing, and actionable alarms for high error rates or latency spikes.
- Infrastructure as Code: Every component provisioned via Terraform or CloudFormation. No manual AWS console changes.
- Resilience & Disaster Recovery: Clearly defined RTO (Recovery Time Objective) and RPO (Recovery Point Objective) targets.
- Cost Controls: AWS Budgets, anomaly detection, and mandatory tag policies.
