Building distributed applications or microservice applications brings a whole new range of problems. All those application components, or microservices, need to communicate with each other. How will we do that: using messaging, or would direct HTTP calls be a better choice? Often, we must make such decisions early in a project. Since it’s hard to change it later, we call it an “architectural decision”. But this is often an excuse so we can blame the architect if the choice turned out to be wrong.
