Assessing readiness for microservices

The decision to adopt a microservices architecture is as much about organizational and technical readiness as it is about aspiration. While the allure of microservices is strong—offering scalability, resilience, and team autonomy—the transition involves considerable complexity. Moving prematurely or without the necessary groundwork can lead to significant setbacks, technical debt, or even failure.

Signals of readiness for microservices

Alberto Acerbis

Alberto Acerbis

Alberto Acerbis is basically an eternal student because the subject matter is endless. He has always defined himself as a backend developer, but he does not disdain poking around on the other side of the code either. He likes to think that 'writing' software is mainly about solving business problems and providing value to the customer, and in this, he finds DDD patterns a great help. I am a co-founder of the DDD Open and Polenta and Deploy communities.
