Design Microservices Architecture with Patterns and Principles - Design Microservices Architecture with CQRS, Event Sour

The video tutorial covers the implementation of CQRS, event sourcing, eventual consistency, and materialized view patterns in microservice architecture. It discusses the design toolbox, functional and non-functional requirements, and the choice of database patterns, including shared, relational, and NoSQL databases. The tutorial explains how to refactor design using these patterns and principles, focusing on an ecommerce application with four main microservices. It highlights the importance of storing events in a write database and using a read database for materialized views, emphasizing the benefits of event sourcing for query performance and scalability. The tutorial concludes with a discussion on database systems, eventual consistency, and the final architecture design.
