System Design Patterns: Major patterns in a single blog post for interviews

This blog post discusses major patterns used in day-to-day software development tasks.

1. Layered Architecture: This is a common design pattern used in many software applications. It divides the system into multiple layers such as presentation, business logic, and data access, making the application more modular and easier to maintain. Click here to study this architecture in depth.

2. Model-View-Controller (MVC): This is another common design pattern that separates an application into three components: model (data), view (user interface), and controller (handles user input). It improves code organization and maintainability. Click here to study this architecture in depth.

3. Event-Driven Architecture (EDA): This pattern allows applications to respond to events in real-time. It uses an event processing system to capture and process events, enabling a more responsive and scalable architecture. Click here to study this architecture in depth.

4. Microservices Architecture: This is a pattern that divides an application into smaller, independent services that can be developed, deployed, and scaled independently. It allows for better fault tolerance and scalability. Click here to study this architecture in depth.

5. Caching: This pattern stores frequently accessed data in a cache, reducing the number of requests to the database or other data sources. It improves performance and scalability. Click here to study this architecture in depth.

6. Service-Oriented Architecture (SOA): This pattern organizes an application into services that can be accessed by other applications or services. It enables loose coupling, reusability, and interoperability. Click here to study this architecture in depth.

7. Publish-Subscribe Pattern: This pattern allows applications to communicate with each other without knowing the recipient’s identity. It involves a publisher sending messages to a message broker, which then delivers the messages to subscribers. Click here to study this architecture in depth.
