Given that the core workflow is "Terraform Infrastructure Builder," we will focus on the architectural design, specifications, and operational considerations that directly translate into robust, production-ready Terraform configurations.
While terms like "wireframes" and "color palettes" are traditionally associated with user interface design, we will reinterpret them to provide actionable insights for infrastructure architecture and visualization. "UX recommendations" will be translated into "Operational Experience (OpEx)" and "Developer Experience (DX)" recommendations for managing and interacting with the provisioned infrastructure.
This step finalizes the comprehensive design for your cloud infrastructure, encompassing all critical components from networking to compute, storage, databases, and security. The output here serves as the blueprint for the subsequent Terraform configuration generation, ensuring that the infrastructure is scalable, secure, cost-effective, and operationally efficient.
Our approach focuses on modularity, reusability, and adherence to cloud best practices, enabling a streamlined deployment process and simplified ongoing management.
These specifications form the granular details that will be translated into Terraform resources.
The proposed architecture is a highly available, multi-tier application environment designed for scalability and resilience, leveraging cloud-native services. It segregates public-facing components from private application and data layers, ensuring a robust security posture.

vpc, ec2-asg, rds, s3).prod, staging, dev with environment-specific variable files.Instead of UI wireframes, we describe the logical structure and flow of the infrastructure. This provides a mental model of how components interact.
* Entry Point: Internet Gateway (IGW) connected to the VPC.
* Load Balancer: Public-facing Application Load Balancer (ALB) resides in public subnets across multiple AZs. It receives traffic from the IGW.
* Bastion Host: Also in public subnets, acts as a secure jump box for administrative access to private instances.
* Application Servers: EC2 instances managed by Auto Scaling Groups (ASGs) reside in private application subnets across multiple AZs. They receive traffic from the ALB.
* NAT Gateways: Reside in public subnets, providing outbound internet access for instances in private subnets without exposing them directly.
* Databases: RDS instances (and ElastiCache, DynamoDB if applicable) reside in private data subnets across multiple AZs. They only accept connections from the private application subnets.
* VPC Endpoints: Services like S3, SQS, SNS are accessed privately within the VPC, bypassing the internet.
Flow: Internet -> IGW -> ALB (Public Subnets) -> Application Servers (Private App Subnets) -> RDS (Private Data Subnets)
* It queries the ElastiCache (Redis) for cached data.
* If not in cache, it connects to the RDS PostgreSQL database in the private data subnet.
* It may interact with S3 (via VPC endpoint) for static assets or file storage.
