System Design Patterns

Here are some basic System Design Patterns 

1. Layered Architecture pattern: This pattern separates the system into distinct layers, each responsible for a specific set of tasks. Each layer can communicate only with the layer directly below it, which helps to enforce modularity and maintainability.

2. Client-Server pattern: In this pattern, the system is divided into two separate parts: the client and the server. The client sends requests to the server, which processes them and sends back a response. This pattern is commonly used for web applications and other distributed systems.

3. Micro-Services Pattern: This pattern breaks down a large system into smaller, independently deployable services that can communicate with each other through APIs. This allows for greater scalability and flexibility, as each microservice can be developed and maintained separately.

4. Event-Driven Pattern: In this pattern, components of the system communicate through events rather than direct calls. When an event occurs, it triggers a chain reaction of other events and actions. This pattern is commonly used for systems that need to handle large amounts of data or user interactions.

5. Model-View-Controller (MVC) pattern: This pattern separates the system into three distinct parts: the model, the view, and the controller. The model represents the data and business logic, the view is responsible for displaying the data to the user, and the controller handles user input and updates the model and view accordingly.

6. Pipes and Filter Pattern: In this pattern, data flows through a series of filters, each responsible for a specific processing task. Each filter takes in data from the previous filter, processes it, and passes it on to the next filter. This pattern is commonly used for data processing systems and batch jobs.
