What Amazon Personalize is
Amazon Personalize is a managed machine learning service that uses customer data to generate item recommendations and user segments. Its options include user personalization, personalized ranking, similar items, personalized search, user segmentation, Trending Now, and Next Best Action. It supports both real-time recommendations and batch workflows. The user-personalization recipe can be trained on up to 3 billion interactions and 5 million unique items. Inference is available through the getRecommendations and getPersonalizedRanking APIs. A search-ranking plugin integrates with OpenSearch v2.9 and above to personalize search results in real time. Listed AWS integrations include SageMaker AI Data Wrangler, Amplify, S3, CloudWatch, and CloudTrail; partner services include Amplitude, Braze, Optimizely, and Segment. AWS says data is encrypted and models are unique to each customer account rather than shared with other AWS accounts or Amazon business units. A free tier is available for the first two months of usage, with monthly allowances for data processing, interactions, training, and real-time requests. Pay-as-you-go pricing has no minimum fees or upfront commitments.
