I really HATE that Azure can not handle virtual IP addresses. Azure broke our application.
In line with another post that I voted for.
I have been working with clustered environments in Linux for many years.
Our application is capable of controlling the failover of a virtual IP address, to the active node in an Active / Passive cluster.
But, the Azure cloud is not capable of assigning an IP address, without being tied to a MAC address.
Our application is now broken!
You need to allow the assignment of virtual IP addresses for clustered environment, active node failover.
