&gt; The module will still affect everything that is dependent upon it if it is rebuilt as a microservice.<p>Your services are running on different servers (or containers) to each other, so they&#x27;re partitioned. If one service has a bug that introduces a catastrophic error that takes all the server resources you&#x27;ll either:<p>Monolith: Bring down the service completely.
Microservices&#x2F;SOA: Timeouts to part of the system, and partial loss of functionality.<p>(Assuming you&#x27;ve done a decent job of engineering for partial failure)
