Deployment with TensorFlow Serving

Introduction Key Concepts Step-by-Step Process Best Practices FAQ

1. Introduction

TensorFlow Serving is a flexible, high-performance serving system for machine learning models designed for production environments. It provides a robust and efficient way to deploy ML models in a scalable manner.

2. Key Concepts

2.1 Model Versioning

TensorFlow Serving allows for versioning of models. This means you can have multiple versions of a model running simultaneously, allowing for easier updates and rollbacks.

2.2 RESTful API

TensorFlow Serving exposes a RESTful API to interact with the model. This allows you to send requests and receive predictions over HTTP.

2.3 gRPC Support

In addition to HTTP, TensorFlow Serving supports gRPC, which allows for faster communication between the client and server.

3. Step-by-Step Process

Note: Ensure you have TensorFlow and TensorFlow Serving installed on your system.

Save your trained model using the TensorFlow SavedModel format.
Install TensorFlow Serving using Docker:

docker pull tensorflow/serving

Run TensorFlow Serving using Docker:

docker run -p 8501:8501 --name=tf_model_serving --mount type=bind,source=/path/to/your/model,target=/models/model_name -e MODEL_NAME=model_name -t tensorflow/serving

Send a request to the model:

curl -d '{"instances": [your_input_data]}' -H "Content-Type: application/json" -X POST http://localhost:8501/v1/models/model_name:predict

4. Best Practices

Use versioning to manage model updates efficiently.
Monitor model performance and set up logging to track usage.
Scale your serving infrastructure based on the load and performance metrics.
Ensure security by implementing authentication on your APIs.
