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
Answer Sari aano?
5 upgrade domains and 10 instances means each domain containing 2 instances. As we know updating a Cloud Service involves updating one upgrade domain at a time. With 5 upgrade domains that would mean 2 of the instances will be updated while remaining 8 will keep on working.
