High Availability using a floating IP

A single VM hosting an application can fail and be offline, which also makes the application inaccessible.

To avoid such a scenario, it is possible to make the floating IP (FIP) high-available, which in turn can be used to make the application high available too.

Active-Passive High-availability

To accomplish a setup like this, we need the following:

1. 2 VMs hosting the application 2. 1 Floating IP 3. 1 VIP (shared IP) RFC1918 from within your project
