Design Microservices Architecture with Patterns and Principles - The Database-Per-Service Pattern - Polyglot Persistence

The video tutorial discusses the database per service pattern in microservice architecture, emphasizing the importance of loosely coupled services. Each microservice should have its own database, allowing for independent scaling and changes without affecting others. The tutorial highlights the benefits of this pattern, such as data encapsulation and polyglot persistence. An example of an e-commerce application is provided, illustrating the use of different databases for product, shopping cart, and ordering microservices. The growing popularity of NoSQL databases in enterprise applications is also discussed.

Explain how polyglot persistence is utilized in microservice architecture.

Describe the types of databases used in the ecommerce application example.
