Design Microservices Architecture with Patterns and Principles - Using Domain Analysis to Model Microservices and Checkl

The video tutorial covers the modeling and decomposition of microservices, emphasizing the importance of designing them based on business capabilities. It highlights the principles of domain-driven design, including bounded contexts and sub-domain models. A checklist for decomposing microservices is provided, focusing on single responsibility, appropriate sizing, and avoiding chatty communication and dependencies. The tutorial concludes with steps to apply these concepts to an e-commerce application, ensuring independent deployment and evolution of services.

What is a key characteristic of microservices that allows them to be changed independently?

• They are designed by business capabilities.

• They are tightly coupled.

• They are loosely coupled.

• They have multiple responsibilities.

What is the main rule for ensuring a microservice is well-designed?

• It should rely on other services.

• It should be as large as possible.

• It should do one thing.

• It should have multiple responsibilities.

Why should chatty communication between microservices be avoided?

• It leads to tightly coupled services.

• It enhances service autonomy.

• It simplifies the design process.

• It increases the size of microservices.

What should be possible when deploying a microservice?

• Deploying with at least two other services.

• Deploying only during off-peak hours.

• Deploying without redeploying any other microservices.

• Deploying all other services simultaneously.

What is the first step in applying domain-driven design to an ecommerce application?

• Defining the bounded context.

• Analyzing the business domain.

• Identifying microservices.

• Applying tactical design patterns.
