Design Microservices Architecture with Patterns and Principles - Introduction - Scale the Microservices Architecture Des

The video tutorial discusses scaling microservice architectures, focusing on both vertical and horizontal scaling. It explains scalability, the differences between vertical and horizontal scaling, and how each method can be applied to handle increased requests. Vertical scaling involves enhancing a single server's resources, while horizontal scaling adds more servers to distribute the load. The tutorial also covers the importance of stateless and stateful applications in scaling and introduces the concept of the scale cube for microservices.

What is the primary goal of scaling a microservice architecture?

• To simplify the codebase

• To decrease the application size

• To reduce the number of servers

• To accommodate millions of requests

Which of the following best describes vertical scaling?

• Reducing the number of requests

• Distributing the load across multiple servers

• Enhancing the power of existing machines

• Adding more machines to the resource pool

What is a limitation of vertical scaling?

• It decreases reliability

• It has maximum capacity limitations

• It is not suitable for distributed architectures

• It requires changing the existing code

How does horizontal scaling improve reliability?

• By reducing the number of servers

• By simplifying the application code

• By adding more CPU and RAM

• By providing redundancy through multiple machines

What is a key consideration when horizontally scaling stateful services?

• Managing state with the CAP theorem

• Ensuring the services are stateless

• Increasing the power of existing machines

• Reducing the number of machines

In the context of microservices, what is the scale cube?

• A method for reducing server costs

• A pattern for scaling monolithic applications

• A concept for understanding scaling dimensions

• A tool for measuring application performance

What is the benefit of applying horizontal scaling to an ecommerce application?

• It reduces the need for an API gateway

• It decreases the number of microservices

• It allows handling more requests with distributed load

• It simplifies the monolithic architecture
