Module 1: VPC

Production-ready multi-AZ networking with VPC endpoints for cost savings.

Features

Networking
VPC Endpoints
Security

3 Availability Zones (configurable)
Public subnets (/20) for load balancers (4,096 IPs each)
Private subnets (/18) for EKS nodes (16,384 IPs each)
NAT Gateways (multi-AZ or single for cost)
VPC Flow Logs to CloudWatch
EKS-optimized tagging for automatic subnet discovery

Usage Example

module "vpc" {
  source = "../../modules/vpc"

  vpc_name = "mcp-production-vpc"
  vpc_cidr = "10.0.0.0/16"
  region   = "us-east-1"

  # Multi-AZ configuration
  availability_zones = ["us-east-1a", "us-east-1b", "us-east-1c"]

  # Subnet sizing
  public_subnet_cidrs  = ["10.0.0.0/20", "10.0.16.0/20", "10.0.32.0/20"]
  private_subnet_cidrs = ["10.0.64.0/18", "10.0.128.0/18", "10.0.192.0/18"]

  # Cost optimization: Single NAT gateway (vs. one per AZ)
  single_nat_gateway = false  # false = multi-AZ (HA), true = single (cost savings)

  # VPC endpoints (saves data transfer costs)
  enable_vpc_endpoints = true

  # VPC Flow Logs
  enable_flow_logs           = true
  flow_logs_retention_days   = 7
  flow_logs_kms_key_id       = aws_kms_key.logs.arn  # Optional encryption

  tags = {
    Environment = "production"
    ManagedBy   = "terraform"
  }
}

Outputs

output "vpc_id" {
  description = "VPC ID"
  value       = module.vpc.vpc_id
}

output "private_subnet_ids" {
  description = "Private subnet IDs for EKS nodes"
  value       = module.vpc.private_subnet_ids
}

output "public_subnet_ids" {
  description = "Public subnet IDs for load balancers"
  value       = module.vpc.public_subnet_ids
}

Cost Breakdown

Component	Monthly Cost	Notes
NAT Gateway (Multi-AZ)	$97.20	3 NAT gateways × $0.045/hour × 720 hours
NAT Gateway (Single)	$32.40	1 NAT gateway (not HA)
VPC Endpoints	$21.60	6 endpoints × $0.01/hour × 720 hours
VPC Flow Logs	~$5.00	Based on log volume
Total (Multi-AZ)	$123.80	Production recommended
Total (Single NAT)	$59.00	Development/staging

Cost Savings: Use single NAT gateway in dev/staging to save ~$65/month. VPC endpoints save ~70% on data transfer costs, paying for themselves with moderate traffic.

Features

Cluster Mode (Production)
Standard Mode (Dev/Staging)

9 total nodes
Automatic sharding
Multi-AZ deployment

Benefits:

Horizontal scaling up to 500 nodes

Use case: Production, high-throughput workloads

Usage Example

module "elasticache" {
  source = "../../modules/elasticache"

  cluster_id     = "mcp-langgraph-prod"
  engine_version = "7.0"
  node_type      = "cache.r6g.large"  # 2 vCPU, 13.07 GB RAM

      name  = "timeout"
      value = "300"  # Close idle connections after 5 min
    }
  ]

  tags = {
    Environment = "production"
    ManagedBy   = "terraform"
  }
}

Outputs

output "configuration_endpoint" {

}

Cost Breakdown

Component	Monthly Cost	Notes
cache.r6g.large nodes (9×)	$496.80	9 × $0.075/hour × 730 hours
Automated backups	~$5.00	7-day retention
CloudWatch Logs	~$2.00	Based on log volume
Total (Cluster Mode)	$503.80	Production
cache.r6g.large (Standard)	$109.50	2 nodes (primary + replica)

Cost Optimization: Use Standard mode with cache.t4g.micro for dev/staging ($24.82/month for 2 nodes).

IRSA (IAM Roles for Service Accounts)

IRSA eliminates the need for long-lived IAM access keys by mapping Kubernetes service accounts to IAM roles.

How IRSA Works

Setup IRSA for Application

Create IAM role via Terraform

# In terraform/environments/prod/main.tf
create_application_irsa_role = true
application_service_account_name = "mcp-server-langgraph"
application_service_account_namespace = "mcp-server-langgraph"
application_secrets_arns = [
  "arn:aws:secretsmanager:us-east-1:123456789012:secret:mcp-langgraph/*"
]

Annotate Kubernetes service account

apiVersion: v1
kind: ServiceAccount
metadata:
  name: mcp-server-langgraph
  namespace: mcp-server-langgraph
  annotations:
    eks.amazonaws.com/role-arn: arn:aws:iam::123456789012:role/mcp-langgraph-prod-application

Use in Pod

apiVersion: v1
kind: Pod
metadata:
  name: mcp-server
  namespace: mcp-server-langgraph
spec:
  serviceAccountName: mcp-server-langgraph  # IRSA annotation
  containers:
  - name: app
    image: mcp-server-langgraph:latest
    env:
    - name: AWS_REGION
      value: us-east-1
    # AWS SDK automatically uses IRSA credentials

Access AWS services

import boto3

# No credentials needed - IRSA automatically provides them
secrets_client = boto3.client('secretsmanager')
response = secrets_client.get_secret_value(SecretId='mcp-langgraph/api-keys')

Benefits of IRSA

No IAM keys: No long-lived credentials to rotate or leak

Automatic rotation: STS credentials expire and rotate automatically

Least privilege: Per-service-account IAM roles

Audit trail: CloudTrail logs all API calls with role assumption

Kubernetes-native: Standard service account annotations

State Management

Terraform state is stored in S3 with DynamoDB for state locking.

Backend Setup

Run backend setup (one-time)

cd terraform/backend-setup
terraform init
terraform apply

Creates:

S3 bucket with versioning and encryption
DynamoDB table for state locking
Access logging bucket

Configure backend in environments

# terraform/environments/prod/main.tf
terraform {
  backend "s3" {
    bucket         = "mcp-langgraph-terraform-state-prod"
    key            = "prod/terraform.tfstate"
    region         = "us-east-1"
    dynamodb_table = "mcp-langgraph-terraform-lock-prod"
    encrypt        = true
    kms_key_id     = "arn:aws:kms:us-east-1:123456789012:key/..."
  }
}

Initialize environment

cd terraform/environments/prod
terraform init  # Migrates state to S3

State Security: The S3 bucket contains sensitive data (database passwords, etc.). Enable:

Versioning (rollback capability)
Encryption (KMS)
Access logging (audit trail)
Bucket policy (restrict access)

Cost Optimization

Total production cost: ~$803/month (60% savings vs. default configuration)

Cost Breakdown

Service	Configuration	Monthly Cost	Savings
EKS	Control plane + 3 general nodes	$434.20	-
RDS	db.t3.medium Multi-AZ	$157.56	40% (vs. db.m5.large)
ElastiCache	2×cache.r6g.large (Standard)	$109.50	78% (vs. 9-node cluster)
VPC	Multi-AZ NAT + endpoints	$123.80	70% data transfer savings
Total		$825.06	~60% total savings

Cost Optimization Strategies

Use Spot Instances (70-90% savings)

enable_spot_node_group       = true
spot_node_group_desired_size = 5
spot_node_group_instance_types = ["t3.large", "t3.xlarge", "t3a.large"]

Savings: $185/month for 5 spot nodes vs. on-demand

Single NAT Gateway (non-production)

single_nat_gateway = true  # Dev/staging only

Savings: $64.80/month (reduces from 3 NAT gateways to 1)

Right-size RDS instances

Dev: db.t3.small ($30.14/month)
Staging: db.t3.medium ($60.28/month, Single-AZ)
Prod: db.t3.medium Multi-AZ ($120.56/month)

Savings: $90.42/month using Single-AZ in staging

ElastiCache Standard vs. Cluster Mode

Standard: 2 nodes (primary + replica) = $109.50/month
Cluster: 9 nodes (3 shards × 3 replicas) = $496.80/month

Savings: $387.30/month using Standard mode when clustering not needed

Cluster Autoscaler

Automatically removes idle nodes:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: cluster-autoscaler
spec:
  template:
    spec:
      serviceAccountName: cluster-autoscaler  # IRSA role

Savings: Variable, typically 20-40% on compute costs

Security Features

Encryption

Secrets: KMS encryption for EKS secrets (automatic key rotation)

RDS: At-rest encryption with KMS, in-transit with TLS

ElastiCache: At-rest and in-transit encryption with KMS

S3 State: AES-256 encryption for Terraform state

Network Isolation

Private subnets: All workloads run in private subnets (no public IPs)

Security groups: Least-privilege firewall rules

VPC endpoints: Traffic stays within AWS network

Network policies: Kubernetes NetworkPolicies for pod-to-pod traffic

IAM

IRSA: No long-lived IAM keys in pods

Least privilege: Per-service IAM roles with minimal permissions

MFA required: For human access to AWS console

CloudTrail: All API calls logged for auditing

Troubleshooting

Error: InvalidParameterException: The following supplied instance types do not exist

Cause: Instance type not available in selected AZsSolution:

# Use instance types available in all AZs
general_node_group_instance_types = ["t3.xlarge", "t3a.xlarge"]

Error: Error creating RDS Cluster: InvalidParameterValue: No subnets in availability zones

Cause: RDS requires subnets in at least 2 AZsSolution:

# Ensure at least 2 AZs
availability_zones = ["us-east-1a", "us-east-1b"]

Error: error waiting for EKS Node Group to be created: timeout

Cause: Node group creation can take 10-15 minutesSolution:

# Increase timeout
terraform apply -parallelism=10 -refresh=true

Pods can't pull images from ECR

Cause: Missing VPC CNI IRSA permissionsSolution: Verify VPC CNI addon is using IRSA role

kubectl describe daemonset aws-node -n kube-system
# Should show: eks.amazonaws.com/role-arn annotation
