Our booking platform experiences higher traffic during the day, requiring server upgrades which cause 10 to 30 minutes of downtime. How can you improve this situation?

To minimize downtime during server upgrades, I would implement a blue-green deployment strategy. This involves running two identical production environments, 'blue' and 'green'. During an upgrade, the new version is deployed to the inactive environment ('green'). Once tested, traffic is switched from the 'blue' environment to the 'green' environment. This allows for zero-downtime deployments. Additionally, leveraging containerization with Docker and orchestration with Kubernetes would enable automated rollouts and rollbacks, further enhancing resilience and minimizing disruption.
