MICROS

What is the primary characteristic of microservices architecture?

• • All functionalities are grouped into a single base of code.

• Divides applications into small, independent services

• • Each service is responsible for a specific function.

• Maintenance and scalability are challenging

What architectural style influenced the development of microservices?

• • Service-Oriented Architecture (SOA)

• • Event-Driven Architecture

• Monolithic Architecture

• Cloud-Native Architecture

What concept did Amazon introduce in 2005 to support microservices?

• • Monolithic scaling

• Two-Pizza Teams

• Agile Scrum Teams

• Continuous Integration/Continuous Deployment (CI/CD)

What is one major disadvantage of monolithic architecture?

• It simplifies scalability.

• Easier testing and monitoring

• Simplified codebase management.

• Difficult to update and redeploy without affecting the entire system.

How do microservices communicate effectively?

• • Through direct database connections.

• Using shared memory.

• REST APIs for lightweight communication

• A single master service coordinating all requests.

What term describes the flexibility of using different languages and tools for each service in microservices?

• Data Decentralization

• Polyglot Programming

• Continuous Deployment

• Modular Codebase

What advantage does decentralized data management in microservices provide?

• • Increased system complexity.

• Single point of failure

• Flexibility and better performance

• Flexibility and better performance

Which principle is fundamental in designing microservices?

• Each service focuses on a single business function.

• Services should be tightly coupled.

• Use heavy protocols for communication.

• Maintain a single codebase for all services.

What are the benefits of using microservices?

• Each service can be scaled independently.

• A failure in one service does not bring down the entire system

• Requires all services to use the same programming language.

• Allows teams to work in parallel on different services.

What challenges are commonly faced with microservices?

• Increased complexity in managing distributed services.

• Maintaining data consistency across multiple databases.

• Lack of flexibility in scaling services.

• • More difficult to test and monitor multiple services in real-time.
