Topic 1 Question 92
You are designing a deployment technique for your new applications on Google Cloud. As part of your deployment planning, you want to use live traffic to gather performance metrics for both new and existing applications. You need to test against the full production load prior to launch. What should you do?
Use canary deployment
Use blue/green deployment
Use rolling updates deployment
Use A/B testing with traffic mirroring during deployment

D due to "full production load"

👍 3GCPCloudArchitectUser2022/02/25 Correct answer is A:
Canary deployment is a technique to reduce the risk of introducing a software update in production by slowly rolling out the change to a small subset of users before making it available to everybody.
This deployment technique is one where the SRE of an application development team relies on a router or load balancer to target individual routes. They target a small fragment of the overall user base with the newer version of the application. Once this new set of users are have used the application important metrics will be collected and analyzed to decide whether the new update is good for a full scale rolled to all the users or whether it needs to be rolled back for further troubleshooting.
