Even though every part of this application is correctly split into each separated microservice, the independence of each service is not enforced. This lack of independence has several drawbacks, one of which is that containers must be started by following a pre-defined startup order. Otherwise, some containers might be terminated due to an application error (the application breaks when an unexpected error occurs, e.g. it is relying on another linked service that is not ready to accept the connection).</p>
