Single Point Of failure means you have only single instance of service and when it fails and does not recover then it is called as SPoF.
If you configure Vahana with only single instance and if it cannot be scaled on break then there is SPoF

@Dilip_Vishwakarma - @naveen.gupta is asking even in HA more, do we have any Single point of failure.

And this third is more targeted to Vahana VRT architecture, rather than the new Vahana, though it might be useful if you can talk about both these VRT.

In some cases, I have seen Vahana completely down, for example, when Redis, API Gateway, or ESB is down. How can we avoid these failures?
