Microservices - Event-Driven ArchitectureWhy might an event-driven microservice architecture be preferred over request-driven for high scalability?ABecause it requires fewer services overallBBecause it forces services to wait for each otherCBecause it eliminates the need for network communicationDBecause it decouples services and allows asynchronous processingCheck Answer
Step-by-Step SolutionSolution:Step 1: Understand scalability factorsHigh scalability requires services to operate independently without blocking each other.Step 2: Evaluate event-driven benefitsEvent-driven architecture decouples services and uses asynchronous messaging, enabling better scalability.Final Answer:Because it decouples services and allows asynchronous processing -> Option DQuick Check:Decoupling + async = scalability [OK]Quick Trick: Async decoupling boosts scalability [OK]Common Mistakes:MISTAKESThinking event-driven forces waitingAssuming fewer services means scalabilityBelieving network is not used
