Microservices Design Patterns

Which design pattern helps in routing the client requests to the appropriate service based on the request type?

• Circuit Breaker

• API Gateway
  

• Service Registry
  

• Sidecar

What is the primary purpose of the Circuit Breaker pattern?

• To manage inter-service communication

• To route requests to the appropriate service

• To prevent cascading failures in a microservices architecture

• To provide service discovery

What is the function of the Service Registry pattern?

• To cache frequently accessed data

• To store configuration settings
  

• To keep track of service instances and their locations
  

• To balance load among different services

What is the main advantage of the Event Sourcing pattern?

---

• Simplifies data synchronization

• Ensures high availability

• Provides real-time analytics

• Allows reconstructing past states by replaying events

What is the purpose of the Strangler Fig pattern?

• To gradually replace legacy systems with new microservices

• To manage distributed transactions

• To implement service discovery

• To handle fault tolerance

Which pattern is used to aggregate responses from multiple microservices into a single response?

• • Chained Microservice Pattern

• Aggregator Pattern

• • Proxy Pattern

• • API Gateway Pattern

Which pattern acts as a single entry point for a defined group of microservices?

• • API Gateway Pattern

• • Aggregator Pattern

• • Proxy Pattern

• • Circuit Breaker Pattern

What is the role of the Proxy Pattern in microservices?

• • To decompose a monolith into microservices

• • To handle synchronous communication between services

• • To offload shared tasks such as security and logging

• • To provide a fallback mechanism for failed services

Which pattern involves splitting a monolithic application by incrementally replacing its functionality with new microservices?

• • Strangler Pattern

• • Circuit Breaker Pattern

• • Proxy Pattern

• • Chained Microservice Pattern

What is the main purpose of the Chained Microservice Pattern?

• • To manage database transactions

• • To chain a series of microservices where each service performs a single task

• • To handle failure in microservices

• • To aggregate responses from multiple services
