AZ-400 – Question 14

You are currently defining a release strategy for an app, named APP-01.

The strategy should allow you to keep the time it takes to deploy new releases of the app to a minimum. The strategy should also allow you to roll back in the shortest time required.

Which of the following is the release strategy you should use?

A. Red/Black deployment
B. Rolling deployment
C. ג€Big Bangג€ deployment
D. Canary deployment 

Correct Answer: A 

Canary deployment –
With canary deployment, you deploy a new application code in a small part of the production infrastructure. Once the application is signed off for release, only a few users are routed to it. This minimizes any impact.
With no errors reported, the new version can gradually roll out to the rest of the infrastructure.
