Design Microservices Architecture with Patterns and Principles - Why Do We Need to Decompose? - The Scale Cube

The video tutorial explains the decomposition of microservices using the scale cube model, which includes three axes: X (horizontal scaling), Y (functional decomposition), and Z (data partitioning). It highlights the importance of identifying parts of an application that require independent scaling and deployment. The tutorial provides examples, such as an ecommerce application, to illustrate different scalability requirements. It emphasizes careful decomposition to ensure scalability and discusses how combining X and Y axis scaling can enhance microservice architecture.

What is the main reason for decomposing microservices?

• To make the system monolithic

• To increase the complexity of the system

• To enable independent scaling and deployment

• To reduce the number of services

Which axis of the scale cube is associated with horizontal duplication?

• X axis

• Y axis

• Z axis

• W axis

What does the Y axis in the scale cube represent?

• Data partitioning

• Functional decomposition

• Vertical scaling

• Service duplication

How does the Z axis differ from the X axis in the scale cube?

• Z axis is unrelated to scaling

• Z axis involves service duplication

• Z axis focuses on data partitioning

• Z axis is about vertical scaling

What is a benefit of combining X and Y axis scaling in microservices?

• Increased system complexity

• Simplified deployment

• Better scalability

• Reduced number of services
