2. Microservice architecture, benefits, and their disadvantages

Question

Accepted Answer

Microservice architecture is a software design pattern where an application is divided into small, independent services.

Benefits of microservice architecture:
- Scalability: Each service can be scaled independently, allowing for better performance and resource utilization.
- Flexibility: Services can be developed, deployed, and updated independently, enabling faster development cycles.
- Fault isolation: If one service fails, it doesn't affect the entire application.
- Technology diversity: Different services can use different technologies, allowing for the best tool for each job.
- Team autonomy: Each service can be developed and maintained by a separate team, promoting ownership and accountability.
Disadvantages of microservice architecture:
- Complexity: Managing multiple services and their interactions can be complex and require additional infrastructure.
- Distributed system challenges: Communication between services introduces network latency and potential failure points.
- Data consistency: Maintaining consistency across multiple services can be challenging.
- Operational overhead: Deploying and monitoring multiple services requires additional effort and resources.
