This sets up a N8n cluster with two Fargate Spot instances and a ALB. It is backed by an EFS file system to store the state. The total costs are around 3 USD per month (provided your ALB is in the free tier). It does not come with SSL (optionally it can listen for SSL connections), but this would raise the cost. You can also use a service like Cloudflare to run the SSL for you.
Note: This module has been setup as a cheap and easy way to run N8n. Data is stored on a EFS volume (you must back this up yourself). We use a single instance (Fargate Spot) so it might be replaced every now and then. N8n is not ment to run stateless behind a load balancer (you will get issues with webhooks).
