The Microservices architecture is a method of developing software applications as a suite of independently deployable, small, modular services. Each service runs a unique process and communicates through a well-defined, lightweight mechanism to serve a business goal. As the buzz around microservices continues to grow, let’s delve into this fascinating world via a series of Multiple Choice Questions (MCQs).
1. What is the primary goal of the microservices architecture?
Answer:
Explanation:
The primary goal of microservices is breaking down large applications into small, independently functioning services.
2. In microservices, how do services typically communicate with each other?
Answer:
Explanation:
Microservices typically interact using lightweight protocols like HTTP/REST or messaging.
3. Which characteristic defines microservices' deployment?
Answer:
Explanation:
A key advantage of microservices is the ability to deploy each service independently, allowing for better scalability and maintenance.
4. What is a major benefit of adopting microservices?
Answer:
Explanation:
Due to their modularity, issues in one service can be addressed without affecting others.
5. What's a common challenge faced when adopting microservices?
Answer:
Explanation:
With each service managing its own database, ensuring data consistency becomes a challenge.
6. To manage inter-service communication in a microservices architecture, what pattern is often employed?
Answer:
Explanation:
An API Gateway acts as a single entry point for clients, directing requests to the appropriate service.
7. Which of the following tools can be used for service discovery in microservices?
Answer:
Explanation:
Eureka, from Netflix, is a popular tool for service discovery, helping microservices find and communicate with each other.
8. What's a common containerization tool used in the microservices world?
Answer:
Explanation:
While Kubernetes is more of an orchestration tool, it works hand-in-hand with containerization tools like Docker to manage and scale containers efficiently.
9. Which pattern is used to deal with the failure of service in a microservices architecture, preventing it from cascading?
Answer:
Explanation:
The Circuit Breaker pattern detects failures and prevents the system from trying a function that's likely to fail, stopping failures from cascading.
10. In microservices, what strategy allows services to be consumers and producers, facilitating asynchronous communication?
Answer:
Explanation:
Event Sourcing captures changes as events, allowing other services to consume and react, promoting asynchronous communication.
11. Which pattern suggests that every service should have its own private database to ensure loose coupling?
Answer:
Explanation:
The Database-per-Service pattern emphasizes that each microservice should own and interact with its own database to ensure they remain loosely coupled.
12. Which pattern helps in tracking the flow of a request across multiple services to diagnose issues and bottlenecks?
Answer:
Explanation:
Distributed Tracing is essential in a microservices environment to track the journey of requests across services and identify potential issues.
