Why Mastering Core Architecture Beats Chasing Every New Framework

Core competence is the ability and experience in architecture design and key detail design; in massive server design it includes physical design (disk storage, memory cache, core data structures, consistency, disaster recovery) and software design (module division, interface definition, design pattern application, core data transfer structures). With these abilities you can implement solutions in C/C++, Java, or Python, showing that language choice matters little.

I completely agree that a professional’s core lies in understanding project and business architecture as well as the principles of each module.

The examples I gave—disk storage design, memory cache design, software design patterns—are not new; they have been around for decades with only minor evolutions.

Many developers worry about new languages and frameworks; if you’re anxious about them, you’re already falling behind.

My response: while backend, especially frontend and app developers, must follow frameworks, only a few companies build their own from scratch. Mastering C++ and computer fundamentals gives you a solid foundation, but you still need frameworks to meet client needs.

Backend Development, Seeking Stability in Chaos

Using Spring, you must study IOC, DI, AOP, and may even write a Spring‑like REST framework. Understanding the principles helps you adapt to framework updates, but each major version (e.g., Spring MVC 1 → 2 → 3 → 5) brings compatibility challenges, and countless third‑party libraries add further pain.

Transitioning from Spring MVC to Spring Boot, and then to Spring Cloud micro‑services, amplifies the difficulty. Even a small third‑party library can become a liability if it stops updating or introduces security risks, forcing costly refactoring.

Developing a full framework from scratch is rarely feasible for small teams due to time and budget constraints; most projects rely on existing solutions.

In China, only Alibaba and Qunar built their own MQ (RocketMQ, QMQ) after evaluating open‑source options and finding them unsuitable for their needs.

Frontend Development, Wailing in the Wilderness

Frontend relies on JavaScript, CSS, and HTML. Since AJAX’s rise in 2005, frameworks have exploded—from prototype to jQuery, Bootstrap, Ext JS, Angular, React, Vue. Even experts who can write frameworks struggle with browser compatibility and breaking changes across major versions.

Only a few companies (e.g., Baidu, Tencent, Alibaba) maintain large‑scale independent frontend frameworks; most developers must work within existing ones.

Frequent UX changes force developers to patch frameworks constantly, adding to the burden.

App Development, Painful to the Core

Early mobile platforms (Symbian, BlackBerry, Windows Mobile) gave way to iOS and Android, forcing developers to switch languages and paradigms.

Android’s fragmentation means each OS version brings massive API changes, deprecations, and short‑lived open‑source libraries—often disappearing within three years.

Testing across hundreds of device models is costly, making “building your own wheel” impractical.

Google’s potential shift to Fuchsia or Flutter could further disrupt developers who haven’t mastered core principles.

iOS developers face similar fragmentation as Apple pushes Swift and reduces Objective‑C support.

Hybrid and cross‑platform solutions (Cordova, Ionic, React, mini‑programs) continuously emerge, each filling one gap only to encounter the next.

Conclusion

There’s a common misconception that only low‑level languages or system programming are “real” development. After years of experience, I respect all languages and frameworks because each brings its own challenges.

Just as car manufacturers use a common engine across models, the engine (core) is essential, but without chassis, body, electronics, and interior engineering a complete product cannot exist. When a model is discontinued, the engine may live on, but other engineers must design new components.

These engineers are also “core” contributors.
