The video tutorial discusses event-driven microservices architecture, highlighting its advantages such as asynchronous behavior and decoupled services. It explains how events can be used in e-commerce applications to streamline processes like order creation and payment. The tutorial contrasts traditional event-driven approaches with evolving methods that incorporate real-time processing and event hubs. It also touches on the integration of big data tools and machine learning for enhanced functionality.

What is a key advantage of using event-driven microservices architecture?

• Increased complexity

• Tightly coupled services

• Synchronous communication

• Asynchronous behavior

In the e-commerce application example, what happens if the payment is unsuccessful?

• The order is rolled back

• The customer is notified

• The stock is updated

• The order is delivered

How do microservices communicate in an event-driven architecture?

• Shared databases

• Event messages

• Direct API calls

• Manual triggers

What role do event hubs play in advanced event-driven microservices?

• They store user data

• They facilitate real-time processing

• They replace microservices

• They handle manual tasks

Which tool is mentioned for processing event upstream data?

• Apache Spark

• Kubernetes

• Apache Hadoop

• TensorFlow
