Software architect 'ardalis' discusses the benefits of Modular Monoliths compared to microservices. Topics include using MediatR, creating online courses, and improving legacy systems. The conversation also covers message brokers, course creation experiences, video editing efficiency, and Dome Train courses.
Modular monoliths offer benefits over microservices for large systems in terms of organization and testing.
Implementing the mediator pattern in code architecture enhances maintainability and consistency across applications.
Deep dives
Importance of Modularity in Code Design
Creating modular code by using encapsulation boundaries and aggregation can prevent issues in large and complex systems. Encapsulating logic within modules or classes allows for better organization and testing, enabling developers to avoid the pitfalls of tightly coupled code.
Benefits of Using Mediator Pattern
Implementing the mediator pattern in code architecture can provide a centralized mechanism for interactions between components. By using mediator behaviors for tasks like validation and logging, developers can streamline repetitive processes, enhance code maintainability, and enforce consistency across the application.
Transitioning from Microservices to Modular Monoliths
Exploring the concept of transitioning from microservices back to modular monoliths can offer cost savings and performance improvements. Understanding the architectural considerations and case studies involving companies like Amazon and Twilio can provide insights into the benefits of opting for a modular monolith approach.
Best Practices for Maintenance Programming
When engaging in maintenance programming, it is advisable to create new code in separate classes or methods rather than modifying existing complex code. By developing new classes that adhere to best practices, such as unit testability and clear separation of concerns, developers can gradually enhance the overall quality and structure of the system over time.
In this episode, I was honoured to be joined by Steve “ardalis” Smith to chat about Modular Monoliths! We discussed the benefits of going down the Modular Monolith route instead of moving to microservices. We also chatted about how MediatR can help with this, and also about creating online courses.
