Bounded contexts play a central role in domain-driven design discussions. They are considered a promising solution for modularizing systems, whether as deployment monoliths or microservices. However, applying them in practice comes with challenges: it is often difficult to divide a domain into bounded contexts. Moreover, the concept is not easy to grasp. On the one hand, it represents the division of a software system into modules; on the other hand, it aims to separate different domain languages within a domain. Additionally, a bounded context is often regarded as a team. How can all of this be reconciled, and how can one work successfully with it in practice? This talk explains what bounded contexts are and then explores these challenges, showing how DDD can make projects even more successful.
