Topic #: 2
You are deploying a new version of your application using the Blue-Green deployment pattern. What is a characteristic of the Blue-Green deployment pattern?
A.
The new version of the application is deployed first, followed by the old version.
B.
The old version of the application is deployed first, followed by the new version.
C.
Both the new and old versions of the application are deployed simultaneously.
D.
The Blue-Green deployment pattern only deploys single versions of the application.
In aBlue-Green deployment, two environments (Blue and Green) exist at the same time. The current version runs in one environment (Blue), and the new version is deployed to the other environment (Green). Traffic is switched to Green once the new version is validated.
“Blue-Green deployments maintain two production environments. The new version is deployed alongside the old version, and once validated, traffic is switched from Blue to Green.”
Thus, the correct answer isC.
