Technical FAQ
01.How does Seldon Core manage model versioning during swaps?
Seldon Core uses a traffic routing mechanism to manage model versioning. By employing canary deployments, it allows gradual traffic shifts from the old to the new model. This is done through configurations in the SeldonDeployment CRD, where you can specify the percentage of traffic allocated to each version, ensuring zero-downtime during the transition.
02.What security measures should I implement for model swaps in Seldon Core?
To secure model swaps, implement TLS for all API communications and OAuth2 for authentication. Additionally, configure Role-Based Access Control (RBAC) to restrict access to sensitive operations within Kubernetes. Regularly audit logs for unusual activities and consider using network policies to control pod communication, enhancing overall security during model deployments.
03.What happens if a new model fails during a zero-downtime swap?
If a new model fails during deployment, Seldon Core can revert traffic back to the previous stable version automatically, thanks to its built-in rollback capabilities. This mechanism ensures that any errors or performance degradations are swiftly mitigated, maintaining service reliability while providing insights into the failure for debugging.
04.Is a specific version of Kubernetes required for Seldon Core deployment?
Seldon Core requires at least Kubernetes 1.18 or higher for optimal functionality. Additionally, ensure that your cluster has sufficient resources allocated for both the Seldon Core components and the models themselves. It's advisable to have a monitoring solution like Prometheus in place for performance metrics and alerting.
05.How does Seldon Core compare to AWS SageMaker for model deployment?
Seldon Core offers more flexibility with on-premise deployments and supports a wider array of model frameworks compared to AWS SageMaker. While SageMaker provides a fully managed service, Seldon allows for advanced custom deployments and integrations with CI/CD pipelines. However, SageMaker may simplify scaling and management at the cost of vendor lock-in.
