Orchestration also aids with zero-downtime deployment: there are many scenarios when your model must be operating 24 hours a day, seven days a week, and 365 days a year, and you may have a new version of the model that you want to update with no downtime. What Kubernetes provides by default is a multi-deployment model, which includes blue and green deployment (either green or blue serving the production version, allowing you to deploy your new version to the other environment, and then switch which production environment serves production) and canary deployment.
