With microservices, one application is split into several microservices. To conquer the complexity associated with multiple microservices and asynchronous event-based collaboration, it is important to have great visibility.
Ensuring high availability means each microservice should be monitored. Automated health management of the microservices becomes important.
Debugging problems needs insights into what's happening behind multiple microservices. Centralized logging with 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.
