Question
Server1 <-> server2 setup?

Asked by mail7e0a6527772c8b16d287b5
Hey, I am running a database and webserver, on one cloud instance (server1).
However I want to have a running backup (server2), so if I need to restart or update server1, i want server2 to be live on my domain. I could change the DNS but that takes 24 hours to react - there must be a better way? Some sort of load balancing server in front of server1 and server2, where I can switch where the traffic should go to? What can you recommend of servers/software for this?
Thanks

Hello,
I could suggest using Haproxy as a load balancer. You could add your server1 and server2 to the pool and that way Haproxy would load balance the traffic to the two servers.
If you need to upgrade server1, you could remove it from the pool and the traffic would be forwarded to server2 only.
For more information you could take a look at this tutorial here:

Hope that this helps! Regards, Bobby
