The video tutorial covers API Gateway patterns and their role in microservices communication. It discusses various patterns like Gateway Routing, Aggregation, and Offloading, and highlights the importance of asynchronous communication using publish-subscribe models and event buses. The tutorial also addresses challenges in direct client-to-service communication, such as increased latency and complexity, and presents API Gateway as a solution to manage these issues effectively.

Which of the following is NOT a pattern related to API Gateway?

• Direct Client Communication

• Gateway Offloading

• Service Aggregator

• Gateway Routing

What is a major problem caused by direct client-to-service communication in microservices?

• Simplified architecture

• Increased complexity and latency

• Reduced latency

• Increased security

How does direct client-to-service communication affect the UI side of an application?

• It reduces the need for protocols

• It increases latency and complexity

• It enhances user experience

• It simplifies the UI

What is the primary role of an API Gateway in microservices architecture?

• To increase latency

• To handle communication requirements and provide cross-cutting concerns

• To replace all microservices

• To eliminate the need for protocols

Which pattern helps manage communication requirements in microservices architecture?

• API Gateway

• Service Aggregator

• Service Registry

• Direct Client Communication
