This document outlines the detailed design specifications, wireframe descriptions, color palettes, and user experience (UX) recommendations for the "Terraform Infrastructure Builder." The goal is to create a robust, intuitive, and production-ready system that enables users to generate modular and secure Terraform configurations for their cloud infrastructure needs.
This section details the structure, modules, variables, and outputs of the Terraform configurations that the builder will generate. The designs prioritize modularity, security, and extensibility, primarily targeting AWS as a default provider but with an architecture that allows for multi-cloud expansion.
The builder will generate a project directory with the following structure:
<project_name>/ ├── main.tf # Main entry point, module calls, and resource definitions ├── variables.tf # All input variables for the configuration ├── outputs.tf # Important output values (e.g., ARNs, IPs, DNS names) ├── providers.tf # Cloud provider configuration (e.g., AWS region, access keys) ├── backend.tf # Remote state backend configuration (e.g., S3, DynamoDB) ├── README.md # Instructions for usage, prerequisites, and outputs ├── modules/ # (Optional) If custom modules are generated or referenced │ ├── vpc/ │ │ ├── main.tf │ │ ├── variables.tf │ │ ├── outputs.tf │ ├── compute/ │ │ ├── main.tf │ │ ├── variables.tf │ │ ├── outputs.tf │ └── ... └── .terraformignore # Files to ignore during Terraform operations
This document outlines the detailed design specifications, wireframe descriptions, color palettes, and user experience (UX) recommendations for the "Terraform Infrastructure Builder" tool. The goal is to create an intuitive, powerful, and production-ready interface that empowers users to generate robust Terraform configurations for various cloud providers.

This document outlines the finalized design assets for the "Terraform Infrastructure Builder" workflow. While the primary output of this workflow is production-ready Terraform configurations, this step interprets "design assets" in two key ways:
The Terraform configurations generated will adhere to the following design principles and specifications, ensuring a secure, scalable, cost-effective, and maintainable cloud infrastructure.
The generated infrastructure will follow a modular, multi-tier architecture, emphasizing best practices for enterprise-grade cloud deployments.
* Isolation: Dedicated VPC per environment (e.g., dev, staging, prod) or per application, with appropriate CIDR block sizing.
* Subnetting: Public and Private subnets across multiple Availability Zones (AZs) for high availability.
* Public Subnets: For internet-facing resources (Load Balancers, NAT Gateways, Bastion Hosts).
* Private Subnets: For application servers, databases, and internal services.
* Network Segmentation: Logical separation of concerns using subnets and security groups.
* Scalability: Auto Scaling Groups (ASGs) for EC2 instances, or managed services like ECS/EKS/Lambda for containerized/serverless workloads.
* Instance Types: Selection based on workload requirements (CPU, memory, network performance).
* AMI Management: Standardized, hardened AMIs.
* Ephemeral Storage: Instance store for temporary data.
* Block Storage: EBS volumes for persistent data attached to EC2 instances.
* Object Storage: S3 buckets for static assets, backups, logs, and data lakes.
* File Storage: EFS/FSx for shared file systems where required.
* Managed Databases: AWS RDS (PostgreSQL, MySQL, Aurora) for relational databases, DynamoDB for NoSQL.
* High Availability: Multi-AZ deployments, read replicas.
* Backup & Recovery: Automated backups, point-in-time recovery.
* Encryption: At-rest and in-transit encryption by default.
* Load Balancing: Application Load Balancers (ALB) for HTTP/HTTPS, Network Load Balancers (NLB) for TCP/UDP, or Gateway Load Balancers (GLB) for third-party appliances.
* NAT Gateways: For private subnet instances to access the internet.
* Internet Gateways: For public subnet internet access.
* Route Tables: Configured for proper traffic flow.
* DNS Resolution: Route 53 for domain management and internal DNS.
* Least Privilege: IAM roles and policies granting only necessary permissions.
* Security Groups & NACLs: Granular network access control.
* Encryption: Data at rest (KMS) and in transit (SSL/TLS).
* Logging & Monitoring: CloudTrail, CloudWatch Logs, VPC Flow Logs.
* Secret Management: AWS Secrets Manager or Parameter Store for sensitive data.
* Right-Sizing: Selecting appropriate instance types and services.
* Lifecycle Policies: For S3, EBS snapshots.
* Tagging: Consistent resource tagging for cost allocation and management.
* Logging: Centralized log collection (CloudWatch Logs, S3, optionally third-party tools).
* Monitoring: CloudWatch metrics and alarms for resource health and performance.
* Tracing: Integration points for distributed tracing (e.g., AWS X-Ray).
A standardized naming convention will be applied across all resources for clarity, consistency, and ease of management.
