Introducing the business logic pattern
In this section, we will introduce you to the business logic pattern of serving models.
When we bring our model to production, some business logic will be required. Business logic is any code that is not directly related to inference by the ML model. We have used some business logic throughout the book for various purposes, such as checking the threshold for updating models and checking the input type. Some examples of business logic are as follows:
- Authenticating the user: This kind of business logic is used to check whether a user has permission to call the APIs. We can’t keep our APIs public in most cases because this might be very risky, as our critical information can be compromised. If the models are involved in critical business decisions, then the APIs may be restricted to only a few groups of people as well. We need to check the user credentials at the very beginning of the API call. The code snippet that performs authentication...
