# Cloud Architect

## Core Philosophy

> "Cloud is not a destination. It is a set of building blocks. Choose the right ones, not the trendy ones."

## Cloud Selection Guide

| Need | AWS | GCP | Azure |
|------|-----|-----|-------|
| Compute | EC2 / Lambda | Compute Engine / Cloud Run | VM / Functions |
| Containers | ECS / EKS | GKE | AKS |
| Serverless | Lambda | Cloud Functions / Cloud Run | Functions |
| Database | RDS / DynamoDB | Cloud SQL / Firestore | Cosmos DB / SQL |
| Storage | S3 | Cloud Storage | Blob Storage |
| CDN | CloudFront | Cloud CDN | Azure CDN |
| ML | SageMaker | Vertex AI | Azure ML |
| IaC | CloudFormation | Deployment Manager | ARM / Bicep |
| Multi-IaC | Terraform (recommended) | Terraform | Terraform |

## Architecture Patterns

### High Availability
```
Region A (Primary)
├── AZ 1a → App + DB replica
├── AZ 1b → App + DB replica
└── AZ 1c → App + DB replica

Region B (DR)
├── AZ 2a → Standby + DB read replica
└── AZ 2b → Standby + DB read replica

Traffic: DNS weighted → Region A (100%) → failover → Region B
```

### Serverless
```
CDN → API Gateway → Lambda/Cloud Run → DynamoDB/Firestore
                                  ↓
                              S3/Bucket (static assets)
                                  ↓
                              SQS/PubSub (async processing)
```

### Microservices
```
CDN → Load Balancer → Service Mesh (Istio/Linkerd)
                          ├── Auth Service
                          ├── Order Service
                          ├── Payment Service
                          └── Notification Service
                          All via: Service Mesh mTLS + observability
```

## Cost Optimization Checklist

- [ ] Right-size instances (no over-provisioning)
- [ ] Use spot/preemptible for batch jobs
- [ ] Reserved instances for steady workloads
- [ ] Auto-scaling with min/max bounds
- [ ] Lifecycle policies on storage (hot → warm → cold)
- [ ] Delete unattached disks and idle resources
- [ ] Tag everything for cost attribution

## IaC Rules

- Terraform preferred (multi-cloud, large ecosystem)
- State in remote backend (S3+DynamoDB / GCS)
- Modules for reusable patterns
- `terraform plan` before `apply`
- No manual console changes — IaC only
