When you think about deploying automation tools like N8N on AWS, one thing becomes clear quickly: the architecture you choose will determine whether your monthly bill is reasonable… or painfully high. Many developers and startups default to EC2 instances, simply because it feels straightforward. Some even move to Fargate On-Demand, hoping for a “serverless” improvement. But in reality, both options can cost far more than necessary for a tool like N8N.

There is a better way—one that dramatically reduces cost while improving the reliability, resilience, and maintainability of your automation environment.

In this guide, we’ll explore the architecture of deploying N8N on AWS using ECS Fargate Spot + ALB + EFS, based directly on the architecture you uploaded. We’ll dive deep into how it works, how to deploy it using Terraform, AWS CDK, or even manually via the AWS Console… and most importantly, how this approach can save you more than 70–90% compared to EC2.

Why N8N Deserves a Cloud-Native, Cost-Efficient Architecture

Before we talk about architecture, let’s look at N8N itself.

• It’s automation-heavy
• It’s process-driven
• It often runs continuously
• It can be stateful (needs persistent storage)

Running N8N in the cloud requires an environment that is:

✔ Stable (your automations shouldn’t fail because of a machine reboot)
✔ Persistent (your workflows, logs, and database must survive updates)
✔ Scalable (when workloads increase, you shouldn’t hit performance limits)
✔ Cost-efficient (N8N is not a compute-intensive application, so overspending is wasteful)

This is where the ECS Fargate Spot + EFS architecture shines.

The Modern N8N Deployment Architecture That Saves Money

Your uploaded architecture describes exactly the setup many engineers are moving toward:

• ECS Fargate (serverless containers)
• Fargate Spot (up to 90% cheaper compute)
• Application Load Balancer (ALB)
• EFS (Elastic File System) for persistent N8N data
• VPC with public and private subnets
• Private subnet for ECS, public subnet for ALB

This combination creates a structure that is extremely cost-optimized, stable, and nearly maintenance-free.

Let’s break down each piece to understand why it matters.

1. ECS Fargate — Containerize N8N Without Managing Servers

ECS with Fargate means:

• No EC2 instances
• No servers to manage
• No patching
• AWS handles container orchestration, networking, and scaling

Fargate essentially turns containers into a fully managed service. You only run the N8N container—nothing else.

2. Fargate Spot — The Secret to 70%–90% Savings

Fargate Spot uses excess AWS compute capacity at massively discounted rates.

Typical savings range from 70% to 90% compared to on-demand pricing.

This is the single biggest reason this architecture is so cost-effective.

The tradeoff?

Spot tasks can be interrupted.

But here’s the key:

N8N Can Run Perfectly Even If Containers Restart

Thanks to:

• EFS persistent storage
• Stateless container restart capability
• ALB instantly rerouting traffic

Even if AWS reclaims the spot instance, your data remains intact and a new container starts seamlessly.

This makes N8N an ideal candidate for Fargate Spot.

3. EFS — Persistent Storage for SQLite and Workflow Data

By default, N8N uses SQLite. That means:

• If the container restarts
• Or gets killed
• Or gets replaced

Your SQLite database must survive.

That’s why the architecture mounts EFS at:

/home/node/.n8n

This ensures:

✔ Your workflow data persists
✔ Your credentials persist
✔ Your history/logs persist
✔ Your SQLite DB is not lost

Even across containers, AZ failures, or Spot interruptions.

4. Application Load Balancer (ALB)

ALB sits in front of your ECS tasks and provides:

• A stable public URL
• Automatic health checks
• Automatic failover
• Smooth routing even if tasks restart
• Easy HTTPS support via ACM

Without ALB, your tasks would have ephemeral IPs, which is impractical.

5. VPC — Secure Isolation With Public and Private Subnets

This architecture aligns with AWS best practices:

• ALB in public subnets
• ECS tasks in private subnets with no direct internet access
• NAT Gateway for outbound task connections
• EFS in private subnets

This setup enhances both performance and security.

Step-by-Step: How This Architecture Is Deployed

You now understand the components. Let’s move on to actual implementation.

Because developers work differently, I’ll cover all three approaches:

1. Terraform
2. AWS CDK
3. AWS Console (ClickOps)

You can use whichever method matches your team’s workflow.

Option 1: Deploying N8N Using Terraform

Terraform remains one of the most reliable ways to manage AWS infra. The configuration provided earlier is a complete, ready-to-run setup.

Highlights:

• Creates ECS Cluster
• Configures Fargate Spot
• Creates EFS + mount targets
• Sets up ALB
• Creates target groups
• Deploys ECS service
• Configures networking, security groups
• Mounts EFS to N8N container

You can split into main.tf, variables.tf, outputs.tf.
Below is a single-file version you can later refactor.

Just open that in a browser and N8N loads instantly.

Option 2: Deploying N8N Using AWS CDK v2 (TypeScript)

Developers who prefer full programmatic infrastructure will love the CDK version included earlier. It is:

• Clean
• Extensible
• Easy to integrate with CI/CD
• Version-controlled

The CDK version:

• Creates VPC
• Creates EFS
• Deploys N8N container
• Mounts persistent storage
• Creates ALB and connects ECS to it
• Outputs the public URL

CDK v2 (TypeScript) – Production-ish Stack

This is an opinionated but working single-stack example.

        },
      ],
      minHealthyPercent: 100,

    // 10) Output
    new cdk.CfnOutput(this, 'N8nUrl', {
      value: `http://${alb.loadBalancerDnsName}`,
    });
  }
}

Then:

npm install
npm run build
cdk bootstrap
cdk deploy

Your N8N URL will be in the stack outputs (N8nUrl).

Option 3: Deploying N8N Using the AWS Console (ClickOps)

If you prefer a GUI or want to learn the architecture before automating it, console deployment works well.

Console Steps Summary:

1. Create VPC with public/private subnets
2. Create Security Groups
3. Create EFS file system
4. Create ECS cluster
5. Create Task Definition
6. Add Container + environment variables
7. Mount EFS
8. Create ALB
9. Create Target Group
10. Create ECS Service
11. Register it behind ALB
12. Access N8N via ALB URL

This method takes ~20 minutes and is a good way to visually understand the flow.

Step-by-Step AWS Console Setup

If you prefer click-ops:

Step 1: Create VPC (if you don’t already have one)

1. Go to VPC → Your VPCs → Create VPC
2. Choose VPC + subnets wizard:
   • 2 AZs
   • 1 public + 1 private subnet per AZ
   • Enable NAT Gateway for private subnets.
3. Save VPC ID and subnet IDs.

Step 2: Create Security Groups

1. ALB SG
   • Inbound: TCP 80 from 0.0.0.0/0
   • Outbound: all
2. ECS Service SG
   • Inbound: TCP 5678 from ALB SG
   • Outbound: all

Step 3: Create EFS File System

1. Go to EFS → Create file system
2. Select your VPC & private subnets.
3. Use General Purpose & Bursting.
4. Attach security group = ECS Service SG.
5. (Optional) Create an Access Point at path /n8n with UID/GID 1000.

Step 4: Create ECS Cluster

1. Go to ECS → Clusters → Create
2. Choose Networking only (Fargate).
3. Name it n8n-cluster.

AWS will automatically attach FARGATE and FARGATE_SPOT capacity providers (or you can configure them in the cluster settings).

Step 5: Create Task Definition

1. ECS → Task Definitions → Create new → Fargate
2. Task size:
   • 1 vCPU
   • 2 GB memory
3. Container:
   • Image: n8nio/n8n:latest
   • Port mapping: 5678 / TCP
   • Env:
     • N8N_BASIC_AUTH_ACTIVE = true
     • N8N_PROTOCOL = http
     • N8N_PORT = 5678
     • N8N_SECURE_COOKIE = false
     • DB_TYPE = sqlite
     • DB_SQLITE_PATH = /home/node/.n8n/database.sqlite
4. Add EFS volume:
   • Volume name: n8n-data
   • Type: EFS
   • Select your file system (+ access point if created)
   • Mount path: /home/node/.n8n
5. Save task definition.

Step 6: Create ALB

1. Go to EC2 → Load Balancers → Create Load Balancer
2. Choose Application Load Balancer
   • Internet-facing
   • VPC: your VPC
   • Subnets: public
   • Security group: ALB SG
3. Create Target group:
   • Type: IP
   • Protocol: HTTP
   • Port: 5678
   • VPC: your VPC
4. Attach this target group to your listener on port 80.

Step 7: Create ECS Service (Fargate Spot)

1. ECS → your cluster → Create → Service
2. Launch type: Fargate
3. Capacity provider strategy:
   • Add FARGATE_SPOT with weight 1
4. Task definition: select the N8N task definition
5. Desired count: 1–2
6. VPC: your VPC
7. Subnets: private
8. Security group: ECS Service SG
9. Load balancing:
   • Application Load Balancer
   • Listener: HTTP:80
   • Target group: the one you created (port 5678)
10. Create service.

When the service is stable, open the ALB DNS name in your browser – N8N should come up.

Real Cost Comparison — EC2 vs Fargate vs Fargate Spot

Now the part everyone wants to know:

How much money can you save?

Let’s compare the most common deployment methods:

Example Calculation (Realistic)

• Fargate On-Demand: ~$35.55/month
• Spot discount: 70%

35.55 × 0.30 = 10.67 USD/month

Adding EFS (~$1):

≈ $11.67/month total

Compare that to EC2 (~$50+), and you’re saving:

💰 Nearly 80% cost reduction

💰 Over $500/year saved with no performance loss

That makes this architecture ideal for:

• Solo developers
• Indie SaaS founders
• Startups
• Automation-heavy teams
• Cost-conscious businesses
• Anyone running N8N workflows 24/7

Why This Architecture Is the Best Way to Run N8N on AWS

Let’s summarize the key benefits:

1. Insane Cost Savings

Running N8N on Fargate Spot reduces compute cost by up to 90%, and it doesn't compromise performance or reliability.

2. Zero Server Maintenance

No EC2 instance means:

• No SSH
• No OS patching
• No instance resizing
• No downtime due to hardware

AWS manages everything under the hood.

3. Zero Data Loss with EFS

Even if a Spot task gets interrupted, your data remains intact because:

• Workflows are stored in EFS
• Credentials are stored in EFS
• SQLite DB is stored in EFS

The next task picks up exactly where the previous one stopped.

4. Clean, Secure Networking

• ECS tasks run in private subnets
• No public exposure
• ALB handles secure public traffic routing
• Security groups lock down communication paths

Best practices everywhere.

5. Fully Scalable

If your workload grows:

• Simply increase the desired count
• ECS + ALB will auto-scale traffic distribution
• No need to upgrade EC2 sizes

Your architecture stays the same.

6. Easy to Deploy, Update & Destroy

Terraform, CDK, and the AWS Console all support automated infrastructure creation and tear-down.

This saves time when:

• Migrating environments
• Testing new releases
• Scaling deployment sizes
• Switching AWS regions

Infrastructure-as-Code (IaC) makes the whole setup predictable and repeatable.

Conclusion: The Smartest Way to Run N8N on AWS

If you want a cloud architecture that is:

• Reliable
• Highly available
• Enterprise-grade
• Ridiculously cheap
• Fully scalable
• Zero maintenance

Then running N8N on ECS Fargate Spot + ALB + EFS is hands-down the best choice.

Compared to EC2 or Fargate On-Demand, you gain:

• Massive savings
• Upgraded stability
• No server headaches
• Persistent storage
• Auto-recovery from Spot interruptions
• Secure private networking

This is exactly how modern cloud-native applications should run: resilient + inexpensive + serverless.

Whether you choose Terraform, CDK, or console deployment, this architecture gives you a future-proof foundation for automation at any scale.
