Design Cloud Architectures and Generate IaC

This agent designs, analyzes, and optimizes cloud infrastructure solutions across AWS, GCP, and Azure, delivering comprehensive architecture recommendations with implementation guidance. It starts with requirements analysis: application requirements, expected load, business constraints, compliance/security/performance needs, budget constraints, and existing infrastructure or migration needs.

It then handles platform selection and service mapping - recommending the optimal cloud platform(s), mapping equivalent services across providers (e.g. EC2/Compute Engine/VMs), identifying managed-service opportunities to cut operational overhead, and considering multi-cloud or hybrid scenarios when beneficial. Architecture design covers high-level diagrams of all components, network topology (VPCs, subnets, security groups), auto-scaling/load-balancing/disaster-recovery strategy, data storage design (databases, object storage, caching), and security best practices (IAM, encryption, monitoring).

Cost optimization calculates estimated monthly cost per component, recommends reserved/spot instances or committed-use discounts, identifies rightsizing opportunities, and plans cost monitoring and alerting. Implementation planning produces a phased deployment roadmap, Infrastructure as Code templates (Terraform, CloudFormation), monitoring/logging/alerting strategy, and backup/disaster-recovery procedures.

The output is an Architecture Summary (platform choice and rationale, key services, estimated monthly cost breakdown, scalability characteristics), a detailed architecture diagram, an Infrastructure as Code sample, and implementation phases (e.g. Foundation weeks 1-2 for VPC/networking/security groups, Core Services weeks 3-4, Application Deployment weeks 5-6, Monitoring and Optimization weeks 7-8). It applies the AWS/Azure/GCP well-architected framework pillars throughout: security-first with defense in depth and least privilege, cost-consciousness with explicit estimates, scalability planning, operational excellence via monitoring/logging/automation from day one, multi-AZ/region high availability, and compliance considerations (SOC2, HIPAA, GDPR) when specified.

Use this agent when a new cloud infrastructure needs to be architected from requirements, an existing setup needs a cost/scalability review, or you're planning a migration to or between AWS, GCP, and Azure. It is well suited to producing a full architecture with cost estimates and IaC templates. It is not meant for a single resource tweak or a quick config change with no architectural implications - a targeted infrastructure change doesn't need a full well-architected review.

Input: application requirements, expected load, budget constraints, and compliance needs.

Output: an Architecture Summary, a detailed architecture diagram, an Infrastructure as Code sample, and a phased implementation roadmap. Example Terraform snippet the agent produces:

resource "aws_vpc" "main" {
  cidr_block           = "10.0.0.0/16"
  enable_dns_hostnames = true
  enable_dns_support   = true

  tags = {
    Name = "main-vpc"
  }
}

resource "aws_autoscaling_group" "web" {
  name                = "web-asg"
  vpc_zone_identifier = [aws_subnet.public_a.id, aws_subnet.public_b.id]
  target_group_arns   = [aws_lb_target_group.web.arn]
  health_check_type   = "ELB"

  min_size         = 2
  max_size         = 10
  desired_capacity = 4
}

Works across AWS, GCP, and Azure, producing Infrastructure as Code via Terraform or CloudFormation, and designs around standard cloud primitives (VPCs, auto-scaling groups, managed databases, load balancers).

Cloud/platform engineers architecting new infrastructure or reviewing an existing one for cost and scalability, and teams planning a migration to or between AWS, GCP, and Azure who need a documented, cost-estimated architecture.
