Design Microservices Architecture with Patterns and Principles - Problem: Cross-Service Queries with Sync Response, Deco

The video addresses a problem in the current microservice architecture related to cross-service queries and synchronous responses. It reviews API Gateway patterns and introduces database-level solutions to avoid direct HTTP calls, which increase coupling and latency. The video discusses the challenges of performing complex joins with low latency and loose coupling. It explores synchronous and asynchronous communication methods and suggests using design patterns like motorized V patterns and secrets design patterns to solve these issues.

What is the main issue faced by the shopping cart microservice in the current architecture?

• Cross-service queries with synchronous response

• Lack of user authentication

• High server costs

• Inability to process payments

Why is it problematic to use direct HTTP calls between microservices?

• It increases server load

• It reduces microservice independence

• It complicates user interface design

• It requires more storage space

What is a key consideration when using synchronous communication in microservices?

• It reduces server costs

• It enhances user experience

• It increases coupling and latency

• It simplifies data storage

Which design pattern is suggested for removing cross-service dependencies?

• Motorized V patterns

• Singleton pattern

• Factory pattern

• Observer pattern

What is the main advantage of using asynchronous communication with message brokers?

• It allows for loose coupling of services

• It reduces the need for databases

• It simplifies user authentication

• It provides immediate responses
