Create Terraform Infrastructure as Code for Cloud Deployment
Generate modular Terraform IaC configurations for cloud infrastructure with networking, compute, database, and security.
📝 The Prompt
Write a modular Terraform configuration to provision a [APPLICATION_DESCRIPTION] infrastructure on [CLOUD_PROVIDER] (AWS, Azure, or GCP). The setup should follow infrastructure-as-code best practices and be ready for a [ENVIRONMENT] environment.
**Infrastructure Components:**
1. **Networking:** VPC/VNet with [NUMBER_OF_SUBNETS] subnets across [NUMBER_OF_AZS] availability zones, including public and private subnet tiers, NAT gateway, and appropriate route tables.
2. **Compute:** [COMPUTE_TYPE] resources (e.g., EC2 Auto Scaling Group, ECS Fargate, AKS cluster, GKE cluster) running [APPLICATION_WORKLOAD] with a minimum of [MIN_INSTANCES] and maximum of [MAX_INSTANCES] instances.
3. **Database:** Managed [DATABASE_SERVICE] (e.g., RDS PostgreSQL, Cloud SQL, Azure Database) with [STORAGE_SIZE] GB storage, automated backups, and multi-AZ/replica configuration for high availability.
4. **Load Balancing:** Application load balancer with HTTPS listener using an ACM/managed SSL certificate for domain [DOMAIN_NAME].
5. **Storage:** Object storage bucket for [STORAGE_PURPOSE] (e.g., static assets, logs, backups) with lifecycle rules and encryption.
**Terraform Requirements:**
- Use Terraform version >= 1.5 with required_providers block
- Organize code into modules: networking, compute, database, load_balancer, storage
- Define all configurable values in variables.tf with descriptions, types, and sensible defaults
- Output critical values (endpoints, IPs, connection strings) in outputs.tf
- Configure remote state backend using [STATE_BACKEND] (e.g., S3 + DynamoDB, GCS, Azure Blob)
- Use locals for computed values and consistent tagging strategy with tags: Project=[PROJECT_NAME], Environment=[ENVIRONMENT], ManagedBy=Terraform
- Include data sources where appropriate instead of hardcoding AMI IDs or region-specific values
**Security:**
- Implement least-privilege security groups / firewall rules
- Enable encryption at rest and in transit for all applicable services
- Use IAM roles/service accounts instead of static credentials
**Deliverables:**
1. Complete file structure with main.tf, variables.tf, outputs.tf, providers.tf, and module directories
2. A terraform.tfvars.example file with sample values
3. Brief comments in each file explaining the purpose of each resource block
💡 Tips for Better Results
Specify your exact cloud provider and region so the AI generates provider-specific resource types and data sources correctly.
Describe your application's traffic pattern (e.g., steady, bursty, low-traffic) in the APPLICATION_WORKLOAD placeholder to get appropriate auto-scaling policies.
Ask for a companion GitHub Actions or CI/CD pipeline to run terraform plan on PRs and terraform apply on merge for a complete GitOps setup.
🎯 Use Cases
Cloud engineers and platform teams who need to scaffold a complete, modular Terraform project for deploying production infrastructure following best practices.
