What is Region in Azure?

Azure operates in multiple data centers around the world. These data centers are grouped into geographic regions, giving you flexibility in choosing where to build your applications. It is important to understand how and where your virtual machines (VMs) operate in Azure, along with your options to maximize performance, availability, and redundancy.
