Understanding Architectural Patterns
Architectural patterns are foundational solutions to recurring design problems in software architecture. They provide a standard way to structure and organize code, enabling better maintainability, scalability, and collaboration.
Why Singleton is an Architectural Pattern
The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance. It is commonly used in scenarios where a single instance is required to coordinate actions across a system.
Key Characteristics of the Singleton Pattern:
Contrasting with Other Patterns
While the Singleton pattern is an architectural pattern, the others listed—Observer, Strategy, and Iterator—are behavioral design patterns. These focus more on the interaction between objects and how they communicate rather than the overall system architecture.
Conclusion
In summary, the Singleton pattern is an architectural pattern because it defines a high-level structure and control over instance creation, making it fundamentally different from other design patterns that address object behavior. Understanding this distinction is crucial for effective system design.

The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance. It is commonly used in scenarios where a single instance is required to coordinate actions across a system.
Key Characteristics of the Singleton Pattern:
- Controlled Access: The Singleton pattern restricts instantiation to a single instance, making it easy to manage shared resources.
- Global Access Point: It provides a global access point to the instance, which is useful in scenarios like configuration settings or logging.
- Lazy Initialization: The instance can be created on demand, which can optimize resource usage.
