Infrastructure Inventory Analysis

Current State (Before This Session)

Existing Resources:

coditect-week1-pilot: Cloud SQL PostgreSQL (coditect-shared-db)
- Database: PostgreSQL 14
- Tier: db-custom-2-8192 (2 vCPU, 8GB RAM)
- Storage: 10GB SSD
- Cost: ~$120/month

Total Projects: 259 GCP projects Active Projects: 6 core platform projects Automated Projects: 250+ sys-* test projects (cleanup recommended)

Detailed Inventory

See: docs/gcp-infrastructure-inventory.md

Key Findings:

No GKE clusters currently deployed
No Citus database (using single PostgreSQL instance)
No Redis cluster
No Kubernetes infrastructure
No monitoring stack

Recommendation: Current architecture suitable for dev/testing (0-10K tenants) but requires full stack deployment for production (1M+ tenants)

Cost Projections

Development Environment (Immediate)

Resource	Configuration	Monthly Cost
GKE Cluster	3 nodes, n1-standard-2	$150
Cloud SQL PostgreSQL	db-custom-4-16384	$300
Redis Cluster	3 nodes, standard	$100
Monitoring	Prometheus/Grafana on GKE	$50
TOTAL DEV		$600/month

Staging Environment (10K-50K tenants)

Resource	Configuration	Monthly Cost
GKE Cluster	6 nodes, n1-standard-4	$500
Citus Cluster	1 coordinator + 3 workers	$2,000
Redis Cluster	6 nodes, HA enabled	$300
Monitoring	Full stack	$200
TOTAL STAGING		$3,000/month

Production Environment (100K-1M+ tenants)

Resource	Configuration	Monthly Cost
GKE Cluster	20 nodes, n1-standard-8	$5,000
Citus Cluster	1 coordinator + 20 workers	$40,000
Redis Cluster	10 nodes, HA + replicas	$1,000
Monitoring	Enterprise stack	$500
Networking	Global LB, Cloud CDN	$500
TOTAL PRODUCTION		$47,000/month

Optimization Opportunities:

Committed Use Discounts: 37-57% savings
Preemptible VMs: 60-91% savings (non-production)
Sustained Use Discounts: Automatic 20-30% savings

Potential Savings: $15K-20K/month at production scale

Security Configuration

Network Security

Configured:

✅ VPC Access API enabled
✅ Service Networking API enabled (VPC peering)
⏸️ Private GKE cluster (pending infrastructure deployment)
⏸️ Firewall rules (pending Terraform modules)

Recommended Next Steps:

Configure private GKE cluster (no public node IPs)
Enable Binary Authorization for container signing
Configure Cloud Armor for DDoS protection
Setup VPC Service Controls

Identity & Access Management

Configured:

✅ 5 service accounts with least-privilege roles
✅ Workload Identity enabled (via GKE API)
✅ IAM policies configured
⏸️ Service account key rotation policy (manual for now)

Recommended Next Steps:

Implement quarterly service account key rotation
Enable audit logging for all IAM changes
Configure resource hierarchy (organization, folders)
Setup IAM conditions for time-based access

Data Protection

Configured:

✅ Secret Manager API enabled
✅ Cloud KMS available (included in enabled APIs)
⏸️ Encryption at rest (CMEK) - pending configuration
⏸️ Backup policies - pending Cloud SQL creation

Recommended Next Steps:

Create customer-managed encryption keys (CMEK)
Configure automated backup schedules
Test backup restoration procedures
Implement point-in-time recovery

Next Steps

Immediate (This Week)

✅ COMPLETED: Create GCP project
✅ COMPLETED: Enable required APIs
✅ COMPLETED: Create service accounts
⏸️ NEXT: Create Terraform modules (P1-T02)

Phase 1: Infrastructure Foundation (Weeks 1-4)

Week 1: Terraform Modules (P1-T02)

Create GKE cluster module
Create Cloud SQL PostgreSQL module
Create Redis cluster module
Create VPC networking module
Create firewall rules module
Integrate Secret Manager

Week 2: Environment Configurations (P1-T03)

Development environment (opentofu/environments/dev/)
Staging environment (opentofu/environments/staging/)
Production environment (opentofu/environments/production/)
State backend configuration (GCS)

Week 3: Kubernetes Base (P1-T04)

Namespace definitions

Migration Considerations

Existing Database (coditect-shared-db):

Can serve as dev/test database initially
Plan migration to Citus when scaling beyond 10K tenants
Implement logical replication for zero-downtime migration

Timeline:

Now - Week 12: PostgreSQL (existing coditect-shared-db)
Week 13-38: Citus staging deployment
Week 39-64: Production Citus migration (blue-green)

Quick Start Commands

Verify Project Setup

# Switch to new project
gcloud config set project coditect-citus-prod

# Verify project
gcloud projects describe coditect-citus-prod

# List enabled APIs
gcloud services list --enabled

# List service accounts
gcloud iam service-accounts list

# Verify billing
gcloud billing projects describe coditect-citus-prod

Create Terraform Service Account Key

# Create key
gcloud iam service-accounts keys create terraform-key.json \
  --iam-account=terraform@coditect-citus-prod.iam.gserviceaccount.com

# Move to secure location
mv terraform-key.json ~/.config/gcloud/keys/

# Set environment variable
export GOOGLE_APPLICATION_CREDENTIALS="$HOME/.config/gcloud/keys/terraform-key.json"

# Verify
gcloud auth application-default print-access-token

Initialize Terraform

# Navigate to Terraform directory
cd opentofu/environments/dev

# Copy example variables
cp terraform.tfvars.example terraform.tfvars

# Edit variables (set project_id, region, etc.)
nano terraform.tfvars

# Initialize Terraform
terraform init

# Plan infrastructure
terraform plan

# Apply (when ready)
terraform apply

Troubleshooting

Issue: "Permission denied" when using Terraform

Solution:

# Verify service account key is set
echo $GOOGLE_APPLICATION_CREDENTIALS

# If empty, set it
export GOOGLE_APPLICATION_CREDENTIALS="$HOME/.config/gcloud/keys/terraform-key.json"

# Verify authentication
gcloud auth application-default print-access-token

Issue: "API not enabled" error

Solution:

# Check if API is enabled
gcloud services list --enabled | grep <api-name>

# Enable API if missing
gcloud services enable <api-name>.googleapis.com

Issue: "Billing not enabled" error

Solution:

# Verify billing
gcloud billing projects describe coditect-citus-prod

# If not enabled, link billing
gcloud billing projects link coditect-citus-prod \
  --billing-account=01C53B-47A12B-A7F32D
