The Production Cloud Infrastructure Pre-Flight Checklist: 5 Gates Before Deployment Before applying Terraform changes, deploying cluster updates, or promoting infrastructure code to production, run through this 5-stage operational readiness checklist: 1. Identity & Access Management (IAM) [ ] Principle of least privilege enforced (zero wildcard * actions on production resources). [ ] Service accounts use short-lived STS tokens or OIDC federation instead of static access keys. [ ] Multi-Factor Authentication (MFA) and conditional IP/context access enforced for administrative roles. 2. Network Architecture & Security Boundaries [ ] Database instances and private microservices reside strictly in isolated private subnets with no public IPs. [ ] Security group ingress rules explicitly define CIDR blocks and specific ports (no 0.0.0.0/0 on management ports like 22, 3389, or 5432). [ ] Egress traffic routes through monitored NAT Gateways or VPC Endpoints for cloud services. 3. High Availability & Resilience [ ] Workloads and data stores span at least two distinct Availability Zones (Multi-AZ). [ ] Auto-scaling policies and Pod Disruption Budgets (PDBs) are configured to handle node-level failures. [ ] Automated backups with point-in-time recovery (PITR) are active and verified with cross-region replication where required. 4. Telemetry, Observability & Guardrails [ ] Centralized structured logging enabled (e.g., VPC Flow Logs, audit logs, container stdout). [ ] Standard alert thresholds set for error rates (5xx), resource saturation (CPU/Memory>80%), and synthetic health probes [ ] An automated rollback strategy or blue/green switch mechanism is verified. 5. Cost & Lifecycle Hygiene [ ] Mandatory cost allocation tags applied (Environment, Service, Owner, CostCenter). [ ] Cloud storage lifecycle rules defined to transition old build artifacts and logs to cold storage. Key Takeaways Eliminate static IAM access keys in favor of short-lived OIDC federated credentials. Never expose database or internal service endpoints to public CIDR blocks. Validate Multi-AZ redundancy and automated point-in-time recovery before pushing live. Enforce cost-allocation tags and automated lifecycle rules across all provisioned resources.
