[CloudFormation template for deploying this stack.](https://github.com/verdaccio/verdaccio/blob/master/contrib/aws/cloudformation-ec2-efs.yaml)
Architecture:

v
Elastic File System
```
Architecture notes:
* Deploy this stack into the region closest to your users for maximum performance.
* We use an auto scaling group primarily for self-healing. The system requirements of Verdaccio are pretty low, so it's unlikely you'll need multiple instances to handle traffic load.
* Because Amazon Linux 2 doesn't include Node, we run Verdaccio as a Docker image rather than natively on the instance. This is faster and more secure than relying on third party package sources for Node.
* Elastic File System is cheap and stateful, and works across AZs. An alternative would be the [third-party S3 storage plugin](https://github.com/remitly/verdaccio-s3-storage).
* For backup, use AWS Backup
Estimated monthly cost for a small installation (in us-east-1):
You can deploy Verdaccio as a task with an [ECS Volume](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/using_data_volumes.html) for persistent storage.
Note: Fargate doesn't support persistent volumes, so you have to use the S3 storage plugin.
