The video tutorial discusses the publish-subscribe architecture, focusing on its evaluation. It highlights the benefits, such as easy addition of subscriber services and scalability, using Kafka as an example. However, it also addresses drawbacks like the single point of failure in message brokers, challenges in debugging asynchronous communication, and issues with FIFO and exact-once requirements.

What is the primary purpose of evaluating an architecture?

• To increase the cost of implementation

• To eliminate all drawbacks

• To redesign the entire system

• To list the benefits and drawbacks

Which of the following is a benefit of the publish-subscribe pattern?

• Reduced scalability

• Higher costs

• Easy addition of new subscriber services

• Increased complexity

What is a potential drawback of having a single message broker in the architecture?

• It can become a single point of failure

• It simplifies debugging

• It ensures exact-once delivery

• It enhances performance

Why is debugging asynchronous communication often challenging?

• Because tracing the flow across services is difficult

• Because it is always synchronous

• Due to the lack of service boundaries

• Because it is always error-free

What issue arises when using traditional message broker systems for FIFO requirements?

• They enhance performance

• They simplify the architecture

• They may not meet performance and scalability needs

• They ensure exact-once delivery
