Semi HA setup with minimum resources

Rancher
1

Hi. I am migrating from Docker Swarm so, Kubernetes and Rancher are afresh to me. After going through the Rancher docs, I got an idea of semi HA setup for us. Keeping our resources in mind I came up with this setup.
At present we run 10 applications and most of them are E-commerce websites and ERP software. The workload is not too high at this moment but we plan to deploy more applications in this cluster.

Now, we need suggestions/feedback from you. Can this setup be considered as an HA?

This looks interesting , a tight budget HA setup is an need of hour for us too. Rancher experts/ other members should throw a light on this.
