Design Microservices Architecture with Patterns and Principles - Problem: Cross-Service Queries and Write Commands on Di

The video tutorial discusses the challenges of the current architecture, focusing on issues with cross service queries and database scaling. It highlights the need to define new problems and improve the design. The tutorial outlines business requirements for highly scaled microservice architectures and presents solutions using patterns like CQRS and event sourcing. The next sections will delve deeper into these concepts.

What is a major challenge in the current architecture related to distributed databases?

• Seamless integration of microservices

• Simple horizontal scaling of databases

• Efficient write commands on distributed databases

• Easy implementation of cross-service queries

Why is it necessary to reconsider commands and queries in a microservices environment?

• To address complexities in cross-service queries

• To enhance database security

• To reduce the number of microservices

• To improve user interface design

What is one of the problems with implementing distributed transaction management?

• It is difficult to implement

• It is easy to scale

• It simplifies the architecture

• It reduces data redundancy

Which pattern is suggested as a solution for improving microservice architecture?

• Client-server pattern

• CQRS design pattern

• Monolithic architecture pattern

• Single database pattern

What will be covered in the next sections of the course?

• Basic programming languages

• Concepts of materialized views, CQRS, and event sourcing

• Advanced database security techniques

• User interface design principles
