Docker Certified Associate Certification Training Course - Advantages of Microservices

The video tutorial explains the benefits of using microservices architecture, highlighting its cost-effective scalability, fault isolation, and ease of problem identification. It emphasizes the localized complexity of microservices, which allows for independent scaling and resource allocation. The architecture enhances business agility, enabling quick experimentation and failure. It simplifies understanding for developers, improving productivity and debugging. Microservices align with business use cases, allowing for easy modification of individual services without affecting the entire application.

What is one of the main advantages of using microservices in terms of scalability?

• They do not support scaling at all.

• They allow for easy scaling due to their loosely coupled nature.

• They require more resources to scale.

• They are difficult to scale independently.

How does fault isolation benefit microservices architecture?

• It increases the complexity of the entire system.

• It causes all services to fail together.

• It ensures that if one service fails, others can continue to operate.

• It makes it harder to identify problems.

Why is localized complexity beneficial in microservices?

• It decreases business agility.

• It requires understanding the entire system.

• It allows teams to focus only on their specific service.

• It makes the entire application more complex.

How do microservices increase developer productivity?

• By making the codebase larger and more complex.

• By allowing developers to focus on small, isolated pieces of software.

• By reducing the need for debugging.

• By requiring developers to understand the entire application.

How are microservices aligned with business use cases?

• They are structured around technical capabilities.

• They are structured around business capabilities.

• They ignore customer viewpoints.

• They make it difficult to improve individual services.
