Define microservices architecture and its primary objective in enterprise applications
回答
Microservices architecture decomposes a monolithic application into independent, deployable services. Each service manages its own business domain, database, and communications. This enables granular scalability, simplified maintenance, and flexible technological evolution based on specific needs of each service.
2Identify the role of Eureka in a Spring Cloud microservices architecture
Identify the role of Eureka in a Spring Cloud microservices architecture
回答
Eureka is a service registry provided by Spring Cloud Netflix. It allows microservices to register dynamically and discover each other without static configuration of IP addresses or ports. This simplifies horizontal scaling and adaptation to infrastructure changes.
3Explain the 'Database per Service' pattern and its benefits in microservices
Explain the 'Database per Service' pattern and its benefits in microservices
回答
The 'Database per Service' pattern assigns a distinct database to each microservice. This ensures service autonomy, avoids direct dependencies on shared schemas, and allows each service to choose the most suitable database technology. However, this complicates distributed transactions and requires mechanisms like sagas.
