The monolithic world has a few advantages of its own. Monitoring and logging is one of those areas where things are easier compared to microservices. The sheer number of microservices across which an enterprise system might be spread can be mind-boggling.
As discussed in Chapter 1, An Introduction to Microservices, in the Prerequisites for a microservice architecture section, an organization should be prepared for the profound change. The monitoring framework was one of the key requirements for this.
Unlike a monolithic architecture, monitoring is very much required from the very beginning in a microservice-based architecture. There is a wide range of reasons why monitoring can be categorized:
- Health: We need to preemptively know when a service failure is imminent. Key parameters, such as CPU and memory utilization, along with other metadata, could be a precursor to...
