Having worked in a payments company, where SLAs can be very demanding,

We broke our monolith server into microservices, and realized that we broke in to too many pieces as our SLAs broke. (every microservice you add to your usecase adds a small but fixed cost)

and finally decided to convert some microservices into libraries to save milliseconds and bring down our 95th percentile, I completely agree with the premise of the article.

never start with microservice, start with monolith with enough flexibility and inbuilt abstractions which can allow you to replace an abstraction with a monolith.
