This document discusses the transition from a monolithic architecture to a microservices architecture at Jobandtalent. It highlights that microservices allow for greater scalability of the platform, teams, and product. Some challenges of microservices include increased complexity of communication and coordination. It provides examples of how Jobandtalent addressed these challenges through tools like message buses and API contracts. Overall, the transition helped Jobandtalent scale to support 10 million users, though adopting microservices was difficult and required waiting for the right time.
