Direct communication between microservices may result in a problem known as Death Star. The Death Star is an anti-pattern where there is communication between the recursion microservices, and making progress becomes extremely complicated or expensive for a product.
With the communication tools we saw previously, it is very easy to establish conversations between microservices with low latency. The common anti-pattern is to allow microservices to exchange messages with each other freely, if they have no information to process a specific task.
This is where we have an alert. If a microservice always needs to communicate with another to complete a task, it is a high coupling signal and we have failed in our DDD process. ...
