You are developing a Microsoft Azure web application. The application will be deployed to
10 web role instances. A minimum of 8 running instances is needed to meet scaling
requirements.
You need to configure the application so that upgrades are performed as quickly as possible,
but do not violate scaling requirements.
How many upgrade domains should you use?
A.
1
B.
2
C.
5
D.
10
Is the answer not B? You have 10 running instances and have to have 8 running at any given time so you’d do deployments to 2 instances at a time..?
