TECHNICAL SUPPORT
Published 2026-01-19
Imagine you have just built a sophisticated robotic arm. The servo motor responds accurately, the servo rotates in place, and everything looks perfect. But when you try to add a new function—for example, letting the robot arm recognize an additional color—you need to change the entire program, and it may even affect the whole body. You have to stop, dismantle much of the structure, and re-commission it. Does this process sound familiar? The tired feeling of stagnation and repetitive work is actually very common in many product developments.
Behind this often lies a technical architecture choice issue: Should we adopt a "monolithic architecture" that bundles all functions together, or a "microservice architecture" that is split into independent modules? Just like when designing a mechanical system, do you use a central controller to manage all the motors, or do you assign independent intelligent modules to each joint?
The traditional monolithic architecture is like packaging all the gears and circuit boards in a big box. It worked well at first, with all the parts working closely together. But as the complexity of the product increases—for example, if you want the device to handle visual recognition, velocity feedback, and trajectory planning at the same time—this "box" can become unwieldy. Every time a small feature is updated, the entire system needs to be recompiled and deployed. What's more troublesome is that if one of these functions fails, it may bring the entire system to a halt.
A friend who is engaged in the development of automated equipment once joked: "Sometimes, I just want to change the steering speed of the servo, but it feels like performing heart surgery on the entire robot." This experience reflects the limitations of a single architecture in terms of flexibility and maintainability.
The microservice architecture takes a different approach. It breaks down the system into a series of small, autonomous services. Each service is like an independent, function-specific micro motor controller: one handles motion trajectory calculations, one is responsible for real-time status monitoring, and the other manages communication protocols. They communicate and cooperate in a lightweight manner, but can be developed, deployed and expanded independently of each other.
Which architecture is chosen directly affects the vitality of the product.
For example, if your product needs to frequently adapt to different customer needs - some customers require high-precision servo positioning, while others are more concerned about the speed of multi-axis linkage - the microservice architecture can show its advantages. You can upgrade Motion Control Services independently without disturbing other parts responsible for Security Checks or Data Logging. It's like replacing just the arm's wrist drive without having to recalibrate the entire base.
On the other hand, if your product functionality is very stable and requirements rarely change, then a compact monolithic architecture may be simpler and more efficient. It avoids the complexity of inter-service communication, and initial development is often faster.
The key is: there is no absolute good or bad, only whether it is suitable or not.
If your project…
And a monolithic architecture may be more suitable...
It's a bit like choosing a transmission solution for your mechanical system: a complex set of timing belts and multiple independent motors (microservices), or a powerful central motor with a linked shaft (monobody)? The answer depends on your trade-offs between flexibility, power and maintenance.
At Kpower, we have observed many projects involving servo drives and precision machinery. Those products that can continue to evolve and easily adapt to market changes often have a kind of "elasticity" in their technical architecture. They don't have to be perfect from the start, but leave room for evolution.
The important thing is not to chase the hottest technical terms, but to understand the practical implications behind each choice. Microservices are not a silver bullet. They bring operational complexity and distributed system challenges. Monolithic architecture is not obsolete. It is still simple and powerful in the appropriate context.
Ultimately, the choice feels like a design conversation. It asks: What kind of “body structure” does your product really need to carry its soul? Should we pursue ultimate unity and simplicity, or embrace flexibility and change? Think about this clearly and the answer will naturally emerge.
A good architecture, like excellent mechanical design, should make people feel that it is what it should be - naturally supporting the operation of the product, unknown but crucial. When you are no longer burdened by technical debt and can focus more on product innovation itself, that calmness may be the best reward.
