How to assign 2 vds one domain?

Question

linux

I have two vds web servers with different ip, I need them to work together under the same domain name, how can I do this????

Answer 1

Round robin DNS?
However, you most likely have 2 different applications on these VDS? Well, write down your subdomain for each of them.

Answer 2

nginx + upstream

Answer 3

I will concretize the answer nikolayvaganov
nginx run in reverse proxy mode. You can put a third machine as a reverse proxy, especially if the VDS has one hoster = save ip.
If different people need HA, you can use Round robin DNS or use Amazon route 53.
