When we are using Static Public IP, then there is no need to update the DNS records each time that the IP address changed. This ensures us that there will be no downtime to our services, while the DNS servers are not updated (a process that can take few hours).
The Azure public IP is a separate service, which we can associate to a new or existing Network Interface or to a load Balance. The Network Interface is associated to Virtual Machine. Therefore, if we are using a Static IP, then we can migrate IP Address from one machine to another. This is a powerful option in cases that we need to migrate services between virtual machines.
In this post I go over the theory of networking is a glance in order to cover the main terms which we all must know, before we start to play with the powerful options that Azure Static Public IP provide us. Next I present several practical scenarios of using static public IP (create IP, associate to existing VM, Migrate between VM, and so on).
