In Chapter 3, Understanding the Microsoft Azure Architecture, you learned about affinity groups.
Using affinity groups, we can make sure compute and storage are close together to keep latency as low as possible. This is necessary because Azure datacenters are huge, and without these affinity groups, the virtual machines could reside on opposite sides of the datacenter. This could result in a performance penalty. With affinity groups, Microsoft promises to keep virtual machines as close together as possible.
Perform the following steps to create a virtual machine:
The first step in the process of creating a virtual machine is to create an affinity group.
To do so, go to the Settings menu item in the left window of Azure Management Portal. Then, select Affinity Groups in the menu bar.
Next, select Add an affinity group.
You will be presented with a window in which you give a name to the affinity group, a description, and select the region.
