How does the digital ocean floating IP work? Could it essentially replace the need for a 'failover' Load Balancer?

I was made aware of Digital Ocean’s floating IP’s when I contacted support with regards to setting up a High Availability Load Balancer. I was also referred to this link:


How exactly does the floating IPs work?

This also made me thinking, if floating IPs allow the smooth switching between droplets, for a simple ‘Failover’ system, why do I even need a Load Balancer? Can’t I just use floating IPs pointing to my Production Server and it’s fail over backup?

Hi there,

With a Load Balancer, you can actually load balance the traffic between your webservers. So that way you can scale up if your traffic grows. Also, the load balancer would do health checks for your servers and forward traffic only to healthy servers.

With a floating IP, one of the servers would be idle all of the time and would only be used when the main server crashes. That way you can’t really scale but you would only have a failover system.

You can use Keepalived for the automatic failover:

Hope that this helps. Regards, Bobby
