The Perils of System Design: Common Mistakes and How to Avoid Them

System design is a critical aspect of software engineering that shapes the backbone of applications, ensuring they are robust, scalable, and maintainable. However, even seasoned engineers can make mistakes that compromise the integrity of a system. In this article, we will explore some common system design pitfalls and how to avoid them.

1. Neglecting Scalability

The Mistake:

Designing systems that work perfectly for a small number of users but crumble under increased load is a common mistake. Scalability is often an afterthought, leading to significant challenges as the user base grows.

How to Avoid:

• Plan for Growth: From the outset, consider how your system will handle an increase in users and data.
• Load Testing: Regularly perform load tests to identify potential bottlenecks.
• Scalable Architecture: Use scalable architectures such as microservices, which allow individual components to scale independently.

2. Overengineering

The Mistake:

In an effort to future-proof a system, engineers sometimes overcomplicate designs, adding unnecessary layers of abstraction and features that may never be used.

How to Avoid:

• Keep It Simple: Adhere to the KISS (Keep It Simple…
