    % : Synchronize user info • This monolith has a knowledge about to which services it has to synchronize its information => Tight coupling (Anti-pattern)
24. • Anti-pattern emerged as a problem under increased traffic • The queues for synchronization got stuck *ODJEFOU

    $PVQMJOH • Each microservice should not have knowledge about other services • Use pub/sub model instead • Microservice just publishes some event • Other microservices subscribe it if needed

    .POPMJUI • When you adopt Microservices, you often need to migrate from monolithic architecture • Legacy monolith is likely to be tightly coupled to other services • Complete migration not to fall into anti-patterns • Otherwise you might end up increasing complexity
