Have two droplets in a RAID type configuration
I am hosting several (30) low traffic Wordpress websites on a droplet and was wondering if there is a way I can have two droplets that are identical. So that I can use a load balancer to ensure that the websites never go offline.
Now I understand that I can clone and use images but if I update or upload content to one of the websites I would have to update the same website on the other server.
In my head I envisage things to run like a RAID harddrive, all data is cloned onto two drives so if one fails the other is still accessible.
Any help or advice is very much appreciated.
