## HA setup using StatefulSets
## HA Setup Using StatefulSets
In order to have higher availability you can setup NATS and NATS
Streaming (STAN) to run in clustering mode. The following commands
will setup a 3 node NATS cluster as well as a 3 node NATS Streaming
cluster that has an attached volume for persistence. Note that you will need more than one node available in your Kubernetes cluster in order for this to work, so in case of deploying onto minikube or docker desktop, please try the single node installer instead.

For NATS Streaming, it is actually recommended to use the Fault
Tolerance mode as that would show better performance than clustering
mode and better failover. You can follow this guide to setup
[NATS Streaming with Fault Tolerance](https://docs.nats.io/nats-on-kubernetes/stan-ft-k8s-aws).
