How NS implements HA mechanism

[Wei-Li_Wang]

Dear Experts.
We have multiple GWs that will be connected to NS simultaneously.
As for NS, each NS is now an independent small computer.
Now, if we want to make these NSs have an HA mechanism, are there any guidelines or better suggestions that can be provided?
I saw in the ChirpStack forum that each architecture seems to be different. Is there any official standard guide or recommended approach for HA or cluster?
Thank you.

Hi there ,
To implement HA, you need to think “component by component”.
For instance, you can implement HA for Postgres (some cloud providers are managing it for you), and connect multiple instances of the front to your HA DB.
Same for REDIS cluster.
The most difficult part will probably be MQTT, where you need to implement shared subscriptions.
Hope this helps.

Here’s what I’m planning to implement:

HA and redundancy for Chirpstack

Hey everyone, I’m looking to add High Availability and redundancy to my postgres/redis/MQTT and was just looking for some suggestions on what people are currently using and what is supported. For redis I am looking at using Redis Sentinel, although I feel I’ve seen comments that sentinel is not supported in the past. Is redis cluster the typical implementation instead? For postgres I am currently looking at using Patroni for handling failover to standby databases. Then have Chirpstack’s postg…

Chirpstack uses shared subscriptions by default these days, MQTT should be relatively easy IMO.
