The best option for deploying a new version of your containerized application to production on GKE and ensuring that the application does not have performance problems after deployment is to deploy the application through a continuous delivery pipeline by using canary deployments, use Cloud Monitoring to look for performance issues, and ramp up traffic as supported by the metrics. A canary deployment is a deployment strategy that involves releasing a new version of an application to a subset of users or servers and monitoring its performance and reliability. This way, you can test the new version in the production environment with real traffic and load, and gradually increase the traffic as the metrics indicate. You can use Cloud Monitoring to collect and analyze metrics from your application and GKE cluster, such as latency, error rate, CPU utilization, and memory usage. You can also use Cloud Monitoring to set up alerts and dashboards to track the performance of your application.

In Site Reliability Engineering (SRE), the most effective way to manage an SLO is through Burn Rate Alerting. According to Google Cloud’s SRE documentation, a burn rate is the speed at which the error budget is being consumed relative to the SLO's compliance period. Relying on simple threshold alerts (Option D) or manual dashboard checks (Option B) often leads to "alert fatigue" or missed signals because they do not account for the rate of depletion over time.

By creating an alerting policy in Cloud Monitoring specifically based on the burn rate, you can identify "fast burns" (sudden outages) and "slow burns" (gradual regressions like increased latency). The system calculates the projection; if the current rate of error budget consumption is high enough to exhaust the remaining budget before the end of the 30-day window, it triggers a proactive notification. This allows the team to intervene while they still have a portion of the error budget remaining, effectively preventing an SLO violation rather than merely reacting to one after the fact. This approach aligns perfectly with Google Cloud's recommended practices for automated, data-driven incident prevention.
