The Open-Closed Principle at an Architectural Level
If you are familiar with the SOLID principles for class design in OOP and if you have ever wondered if you can use them, for example the Open-Closed Principle, when designing the architecture of a system. The Open-Closed Principle, with microservices? Madness! Well, maybe not. Let's dive into it and check it out.
