Terraform Cloud Patterns ☁️

Multi-cloud Infrastructure as Code modules for AWS, GCP, and Yandex Cloud. Production-tested Terraform patterns with FinOps cost optimization.

🌐 Supported Clouds

Provider	Module	Features
AWS	modules/eks-cluster	EKS with spot instances, auto-scaling
GCP	modules/gke-autopilot	GKE Autopilot, Workload Identity
Yandex Cloud	modules/yc-managed-k8s	Managed Kubernetes, IAM integration

🚀 Quick Start

AWS EKS Cluster

module "eks" {
  source = "./modules/eks-cluster"

  cluster_name       = "production-eks"
  cluster_role_arn   = aws_iam_role.eks.arn
  kubernetes_version = "1.28"
  subnet_ids         = ["subnet-abc123", "subnet-def456"]
  
  cost_center = "platform-engineering"
  tags = {
    Environment = "production"
    Team        = "devops"
  }
}
Deploy
bash
terraform init
terraform plan -out=tfplan
terraform apply tfplan
💰 FinOps Features
Cost Optimization Built-in:

Spot instance support for EKS node groups

Budget alerts via CloudWatch/Stackdriver

Resource tagging for cost allocation

Right-sizing recommendations in outputs

Example cost tracking:

text
tags = {
  CostCenter  = "engineering"
  Project     = "api-platform"
  Environment = "prod"
}
🔄 CI/CD Integration
GitHub Actions automatically validates Terraform:

Format checking (terraform fmt)

Syntax validation (terraform validate)

See .github/workflows/terraform-validate.yml

🎯 Use Cases
Cloud Migrations: Migrate from on-premise to AWS/GCP/Yandex

Multi-Region Deployments: DR/HA across availability zones

Cost Optimization: FinOps tagging + spot instances

GitOps Workflows: Integrate with ArgoCD/Flux

🤖 AI-Augmented Infrastructure (Experimental)
Coming soon: ML-based cost prediction and auto-scaling recommendations.
