Pros & Cons of using microservices

Pros: Easier to test, deploy, and monitor since each service works independently,

service can scale better at a specific bottleneck
can serving older and newer version at the same time, and let older ones phase out gradually
development, test & deployment of each service is independent

Cons: latency between services and management issue

A service depending on several calls to others may suffer from a huge delay
different teams may work on the same/similar service at the same time, extra assessments are needed.

Besides, good documentation is always needed and a discovery tool also make operation easier.
