after reading through the documentation I’m a little bit confused about how to deploy Node-RED to AWS with high availability.
https://nodered.org/docs/getting-started/aws mentions, that EFS is requires for an HA deployment.
However, there is also an S3 storage provider. As far as I understand the concept of a storage provider, by using the S3 storage provider all data will be stored on S3. Or is there some data that is still stored on local disk?
Is using EFS required for a HA infrastructure aka. multiple nodes running in parallel? Or is using the S3 storage provider not requiring EFS any more?
Can someone please help me understand the details here?
