Alibaba Cloud Machine Learning Platform for AI (PAI) provides an all-in-one solution for both traditional machine learning and deep learning. This platform integrates data processing, model training, service deployment, and online prediction. The deployment of an online prediction service is an important step of applying algorithm models to actual business. To help users apply algorithms from end to end, PAI provides Elastic Algorithm Service (EAS) to support online prediction services that are used in scenarios where online inference is involved.
EAS allows you to publish models to API Gateway by using RESTful API operations. Models that are published to API Gateway can be called in business systems by using HTTP requests. For information about how to publish models to API Gateway, see Model Calling Methods.
