Setup redundant servers with openremote
Budget: $30 – $250 USD
I would like to setup fully redundant system Of openremote.
Openremote come in docker container packages so my My thoughts are listed below. But I would like a sysadmin perspective on making a redundant setup with a clear upgrade path as the load on the servers grow.
At first I think it would be best to have two small VPS, that each contain the 4 docker containers.
1. HAProxy
2. Postgressql
3. KeyCloak
4. Manager
Then use haproxy for load balancing and fail over between the two VPS, that each have manager, haproxy and keycloak instances. And have the database setup for replication.
Each server could be setup with its own external up and domain etc. Et1 and et2 and then the proxy could receive euncoming traffic in "et" and spread the load to et1 and et2
No single point of failure.
Easy upgrade path as we can split out each of the containers for its own redundant pair of vps. I guess next step would be two dedicated vps for DB.
THOUGHTS?
And bits on the exact time and usd$$ you belive it would take.
Also please make a note if you have experience wirh openremote platform.
