You support a web application that is hosted on Compute Engine. The application provides a booking service for thousands of users. Shortly after the release of a new feature, your monitoring dashboard shows that all users are experiencing latency at login. You want to mitigate the impact of the incident on the users of your service. What should you do first?
MITIGATE is the keyword here. Increasing resources will not guarantee the mitigation. Rolling back will do this. This would be the quickest way to remove the new feature that is causing the latency and restore the application to its previous state. This would immediately mitigate the impact on users, while you continue to investigate the issue with the new feature and identify a long-term solution.
A. Roll back the recent release.
B. Review the Stackdriver monitoring.
C. Upsize the virtual machines running the login services.
D. Deploy a new release to see whether it fixes the problem.
