Load balancer vs dns vs floating ip
Currently I have the following setup:
My domain is pointed to the floating ip, that point on one of the two loadbalancer that point on one of the two apache server.
The reason it was done like this is that we need to never have a single point of faillure.
But is it a little bit overkill, and what is the point of all the parts?
I means, if on godaddy, I setup the dns to send all @ to both apache server ip, will it have the same result?
Or if I make the dns to send all to the loadbalancer?
Or maybe skip the loadbalancer and point the floating ip directly to the apache server?
What would be the best setup to be sure to never have any downtime?
