Recently, Microsoft confirmed the retirement of three Azure AI services: Personalizer, Anomaly Detector and Metrics Advisor.
Azure AI Personalizer enabled applications to make better decisions at scale using reinforcement learning. Personalizer processed information about the state of the application, scenario, and/or users (contexts), as well as a set of possible decisions and associated attributes (actions) to determine the best decision to make. Microsoft has confirmed that the Azure AI Personalizer service will be retired on October 1, 2026 and you will not be able to create a new Personalizer resource from now on.
Azure AI Anomaly Detector lets you monitor and detect anomalies in time series data with less machine learning (ML) knowledge, whether in batch validation or real-time inference. Microsoft has confirmed that the Azure AI Anomaly Detector service will be retired on October 1, 2026 and you will not be able to create a new Anomaly Detector resource from now on.
Azure AI Metrics Advisor lets you perform data monitoring and anomaly detection in time series data using the power of AI. The service automates the process of applying models to your data and provides a set of APIs and a web workspace for data ingestion, anomaly detection and diagnostics, without the need to know how to learn automatic. Microsoft has confirmed that the Azure AI Metrics Advisor service will be retired on October 1, 2026 and you will not be able to create a new Metrics Advisor resource from now on.
In addition to the three above, Microsoft is also retiring Azure Spatial Anchors which allows you to create, curate and share 3D content or real-scale points of interest across different platforms and devices.
Microsoft did not provide any reason why it was discontinuing the above services. I suspect these services are being retired as Microsoft focuses on strategic areas of long-term growth and long-term competitiveness for the company.
