What is a significant advantage of microservices in cloud-native applications?

• A. They require a single, centralized data model.
• B. They complicate deployment and management.
• C. They enhance flexibility and make the application easier to manage.
• D. They eliminate the need for monitoring and observability.

Answer: (B)

Modularity and independent deployability of microservices give cloud-native apps their notable advantage: increased flexibility and easier management. By breaking the application into small, self-contained services, teams can develop, test, deploy, and scale each piece separately. This means you can update a single service without touching the entire system, choose the best technology for each service, and scale components that need more resources while leaving others unchanged. This granularity also helps with fault isolation—a problem in one service is less likely to bring down the whole application. Centralized data models clash with this approach, because microservices favor each service owning its own data to maintain loose coupling. While managing multiple services can introduce some complexity, the payoff is the ability to deploy and evolve parts of the system rapidly and independently. And monitoring remains essential in a distributed setup; you still need observability to understand how services interact and to detect issues across the system.
