Ok again i want to setup Floating IP.
Do you know what floating IP is? Did you read the link i sent to know what the use of floating IP is? Floating IP is NOT a loadbalancer, it is used to direct traffic to particluar server or virtual machine without the virtual machine knowing the IP.
The same link i sent has all this information https://www.digitalocean.com/company/blog/floating-ips-start-architecting-your-applications-for-high-availability/
