🧙🏻♂️ Types of System Design & Patterns in Software Engineering
If you've been building software for a while, you've probably heard phrases like:
- “Let’s make this event-driven.”
- “This should probably be a microservice.”
- “Maybe a strategy pattern fits here.”
These aren’t random buzzwords. They are software patterns.
A software pattern is a reusable solution to a problem that engineers encounter repeatedly while designing systems or writing code.
Instead of reinventing the wheel every time, developers rely on patterns that have already proven to work well.
Over the years, hundreds of patterns have been documented. Fortunately, most of them fall into a few major categories.
In this article, we’ll walk through the major types of patterns used in modern software engineering:
- 🏗 Architectural Patterns
- 🧩 Design Patterns
- 🌐 Distributed System Patterns
- 🗄 Data Management Patterns
- ⚡ Concurrency Patterns
- 📡 Integration & Messaging Patterns
By the end of this guide, you’ll have a clear mental map of where different patterns live in the system design landscape.
