Implement distributed logging to collect, store, and analyze log data from service instances, include

information about service calls, errors, performance metrics, and other relevant data.

▪ Implement distributed tracing to track the flow of requests through the system.

▪ If a user adds an item to their shopping cart, the trace with information about the request flows from the

shopping cart service to the payment processing service to the product catalog service.
