NVIDIA Triton Inference Server
- See also: Deployment
Introduction
NVIDIA Triton Inference Server is an open-source solution that streamlines model deployment and execution, delivering fast and scalable AI in production environments. As a component of the NVIDIA AI platform, Triton allows teams to deploy, run, and scale AI models from any framework on GPU- or CPU-based infrastructures, ensuring high-performance inference across cloud, on-premises, edge, and embedded devices.
Features
Support for Diverse Frameworks
Triton supports numerous training and inference frameworks such as TensorFlow, NVIDIA TensorRT, PyTorch, Python, ONNX, XGBoost, scikit-learn RandomForest, OpenVINO, custom C++, and more. This versatility empowers AI researchers and data scientists to select the most suitable framework for their projects without impacting production deployment.
High-Performance Inference
Triton enables inference on NVIDIA GPU-, x86-, Arm CPU-, and AWS Inferentia-based platforms. By offering dynamic batching, concurrent execution, optimal model configuration, model ensemble, and streaming audio/video inputs, Triton maximizes throughput and resource utilization.
DevOps and MLOps Integration
Designed with DevOps and MLOps in mind, Triton seamlessly integrates with Kubernetes for orchestration and scaling, exports Prometheus metrics for monitoring, supports live model updates, and is compatible with major public cloud AI and Kubernetes platforms. Many MLOps software solutions also integrate with Triton.
Model Ensembles and Pipelines Support
Triton accommodates modern inference requirements, such as multiple models with pre- and post-processing for single queries. It supports model ensembles and pipelines, executing ensemble components on CPU or GPU and utilizing multiple frameworks within the ensemble.
Accelerating AI in Various Applications
Triton delivers high-throughput inference by concurrently executing multiple models on a single GPU or CPU. With dynamic batching, Triton optimizes real-time inferencing under strict latency constraints and supports batch inferencing to maximize GPU and CPU utilization. Furthermore, Triton provides built-in support for audio and video streaming input and enables live updates of models in production without server or application restarts.
Scalability and Integration Ease
Available as a Docker container, Triton easily integrates with Kubernetes for orchestration, metrics, and autoscaling. It supports the standard HTTP/gRPC interface for connections with other applications, such as load balancers, and can scale to any number of servers for handling increasing inference loads for any model.
Python Native Support
PyTriton offers a user-friendly interface for Python developers to utilize Triton Inference Server for serving models, processing functions, or entire inference pipelines. This native support in Python facilitates rapid prototyping and testing of machine learning models while maintaining high hardware utilization.
Model Orchestration with Management Service
Triton introduces a new model orchestration functionality for efficient multi-model inference. This production service loads models on-demand, unloads inactive models, and allocates GPU resources effectively by placing as many models as possible on a single GPU server. The model orchestration feature is currently in private early access.
Large Language Model Inference
Triton supports inference for large language models like GPT-3 and Megatron, which may not fit on a single GPU. It can partition the model into smaller files and execute each on a separate GPU within or across servers.
Optimal Model Configuration with Model Analyzer
The Triton Model Analyzer is a tool that automatically evaluates model deployment configurations, such as batch size, precision, and concurrent execution instances on the target processor. It assists in selecting the optimal configuration to meet application quality-of-service (QoS) constraints, reducing time spent on finding the ideal configuration.
Tree-Based Model Inference with Forest Inference Library (FIL) Backend
The Forest Inference Library (FIL) backend in Triton enables high-performance inference of tree-based models with explainability (SHAP values) on CPUs and GPUs. It supports models from XGBoost, LightGBM, scikit-learn RandomForest, RAPIDS cuML RandomForest, and others in Treelite format.
Ecosystem Integrations
Triton is supported by a variety of cloud platforms and services, including Alibaba Cloud, Amazon Elastic Kubernetes Service (EKS), Amazon Elastic Container Service (ECS), Amazon SageMaker, Google Kubernetes Engine (GKE), Google Vertex AI, HPE Ezmeral, Microsoft Azure Kubernetes Service (AKS), Azure Machine Learning, and Oracle Cloud Infrastructure Data Science Platform.
