To handle network failures gracefully

To enforce security policies

11. Explain the concept of service discovery in microservices architecture and its role in communication between services.

Service discovery is unnecessary in microservices.

Service discovery helps services find and communicate with each other.

Service discovery is only relevant in monolithic architectures.

Service discovery focuses on hiding services from each other.

12. Discuss the role of centralized logging in microservices architecture and its benefits.

It promotes fault isolation

It discourages service encapsulation

It hinders troubleshooting

It provides a unified view of application logs

13. What is a common challenge in microservices architecture related to data management?

Data duplication

Data centralization

Data consistency

Data encryption

14. What is the purpose of an API Gateway in a microservices ecosystem?
