一覽

KServe is a Kubernetes-native platform for deploying ML models (PyTorch, TensorFlow, SKLearn, etc.) with auto-scaling, traffic splitting (canary), monitoring, and explainability. Used by ML teams at Google, Kubeflow, and enterprises running inference at scale. Mastery takes 4-6 months. Senior practitioners command 20-30% premium because ML deployment is specialized and valuable.

什麼是 KServe Model Server

KServe is a Kubernetes-native platform for deploying and serving machine learning models. It provides model serving abstraction (supports PyTorch, TensorFlow, SKLearn, XGBoost, custom models), auto-scaling based on traffic, traffic splitting (canary, A/B testing), monitoring, and model versioning. KServe runs on Kubernetes via KNative, enabling serverless inference: models scale to zero when idle, spin up on demand.

❓ 常見問題

Should I use KServe or BentoML?
KServe: serverless on Kubernetes, auto-scaling, multi-framework, canary deployments. BentoML: simpler, containerized services, easier for small teams. KServe: large-scale, multi-tenant. BentoML: teams with single/few models. KServe steep learning curve; BentoML easier onboarding.
Can KServe scale to 10k+ requests/sec?
Yes, that's its strength. KNative + Kubernetes auto-scaling handle massive load. Batching, caching, and GPU acceleration improve throughput. Teams run 100k+ req/sec with KServe.
How do I do canary deployments with KServe?
KServe integrates with Istio for traffic splitting. Deploy v2 model, route 5% traffic to it. Monitor error rate. If healthy, shift 50%, then 100%. Full canary without manual infrastructure work.
Can I use GPUs with KServe?
Yes. Kubernetes allocates GPUs, KServe manages model scheduling. Specify GPU requests in model spec. KServe batches requests to maximize GPU utilization.
What's the difference between predictor and transformer?
Predictor: runs raw model (neural network input → output). Transformer: pre/post-processes data (normalize features, format output). Chaining them: transformer → predictor → output formatter.
