With microservices, one application is split into several microservices. To conquer the complexity that is associated with multiple microservices and asynchronous event-based collaboration, it is important to have great visibility.

Ensuring high visibility means each microservice should be monitored. Automated health management of the microservices becomes important.

The debugging of problems needs an insight into what's happening behind multiple microservices. Centralized logging with the aggregation of logs and metrics from different microservices is typically used. Mechanisms such as correlation IDs need to be used to isolate and debug issues.
