High availability is an important aspect in running production systems. To this end, you can add Pod Disruption Budget Specifications to the Pod Template Specifications you create. Depending on how you want your application to handle disruptions, you can define your disruption budget accordingly.
An example Seldon Deployment with disruption budgets defined can be seen below:
apiVersion: machinelearning.seldon.io/v1 kind: SeldonDeployment metadata: name: seldon-model spec: name: test-deployment replicas: 2 predictors: - componentSpecs: - pdbSpec: minAvailable: 90% spec: containers: - image: seldonio/mock_classifier_rest:1.3 imagePullPolicy: IfNotPresent name: classifier resources: requests: cpu: '0.5' terminationGracePeriodSeconds: 1 graph: children:  endpoint: type: REST name: classifier type: MODEL name: example
This example ensures that our serving capacity does not decrease by more than 10%.
