The philosophy of 'Write programs that do one thing and do it well' highlights the importance of Separation of Concerns (SoC) in modern software development.
SoC involves designing software as modular components that serve distinct functions and operate independently, aligning with principles like DRY, SOLID, and clean architecture.
It's restated as the single responsibility principle, emphasizing that each unit of software should have a well-defined purpose.
SoC helps break down large projects into manageable, focused components, aiding in the structuring of any system.
While AI-driven development advances, SoC remains relevant by aiding in modularity and API-driven microservices.
Separating concerns creates extensible, adaptable software that is easier to maintain and scale.
It reduces duplication, improves discoverability, and leads to well-structured projects that evolve alongside business needs.
A real-world example of SoC can be seen in decoupled identity systems like CIAM, which rely on modular components with distinct responsibilities.
While some argue against microservices architectures, SoC plays a role in defining clear boundaries even in monolithic development.
Despite shifts in software trends, SoC remains essential for scalable architecture and digital transformation efforts in modern development.
Knowing when to separate concerns and understanding the business impact and maintenance implications is an intuitive process crucial for technical leaders.
