Design Microservices Architecture with Patterns and Principles - Design the Architecture - Microservices Architecture -

The video tutorial discusses transitioning from a monolithic to a microservices architecture to address scalability and deployment challenges. It emphasizes the need for both technological and organizational changes, outlines functional and non-functional requirements, and introduces key patterns like database per service and polyglot persistence. The tutorial also highlights the benefits of microservices, such as independent deployment and resilience, and suggests future improvements for the architecture.

What is one of the main problems with the previous modular architecture?

• Inability to scale and deploy independently

• High cost of maintenance

• Lack of security

• Complexity in user interface design

Which of the following is a non-functional requirement adapted for microservices architecture?

• User experience enhancement

• High availability

• User interface design

• Cost reduction

What pattern is used to ensure each microservice has its own database?

• Database per service pattern

• Distributed database pattern

• Centralized database pattern

• Shared database pattern

How do microservices communicate with each other in the described architecture?

• Shared memory

• REST APIs

• Direct database access

• File transfer

What principle is followed to ensure services are organized by business capabilities?

• Open/closed principle

• Dependency inversion principle

• Interface segregation principle

• Single responsibility principle
