While not explicitly mentioned in the provided information, we can infer that John Mosquera likely employed several strategies to minimize downtime during updates or maintenance, given the high uptime achievement. He probably implemented rolling updates, which allow for gradual replacement of old pods with new ones, ensuring continuous service availability. Blue-green deployments or canary releases might have been used for major updates, allowing for easy rollback if issues were detected. John's implementation of cross-region replication would have enabled maintenance on one region while serving traffic from another. The use of pod disruption budgets likely ensured that a minimum number of pods remained available during voluntary disruptions. Additionally, the comprehensive monitoring setup would have allowed for careful scheduling of maintenance during low-traffic periods and quick detection of any issues during updates. John likely employed strategies such as rolling updates, blue-green deployments, and carefully scheduled maintenance windows, leveraging his cross-region setup and comprehensive monitoring to minimize downtime during updates or maintenance of the Kubernetes clusters.
