In this final part of the book, we want to see how our anomaly detection engine stacks up to the competition. Chapter 18 will briefly review three competitors from public cloud providers Amazon, Microsoft, and Google. We will also set up an account with Microsoft’s Azure Cognitive Services Anomaly Detector service and try it out. Finally, in Chapter 19, we wrap up the book with a bake-off, comparing our engine to the Cognitive Services anomaly detection service. We will review the results of this bake-off and close with ideas on how to make our anomaly detection engine and service better for users.
