Each microservice is considered as an independent element, and all the elements together form the overall process body. This makes microservices reusable and well-debugged.
Simplified Event Logs Reading
When using BPMS, the business can see how the code works on well-designed and comprehensible diagrams. Speaking about the logging, all log files have a unique format, and the cause-effect relationship analysis becomes as simple and comprehensive as possible for the entire business process.
Variations in the Use of Programming Languages
Each microservice is an independent piece of code. Sometimes you need to combine different stacks (for refactoring or acceleration), and this is not a problem in the microservice approach.
BPM System Integration
With the integration of BPM systems (such as Camunda or jBPM), microservices are easier to manage and control – business processes are executed according to the BPMN 2.0 standards. Algorithms become self-documenting and transparent for business.
The Opportunity of TDD Use
It can be difficult to use TDD in modular systems due to the strong functional connectivity. As a result, the vast majority of modules are without TDD. Microservices can provide resistance to regression even for a highly complex development.
Easy to Scale
At the cluster level, you can scale a particular microservice, instead of all the components, which is typical of modular systems.
