## Stateless System

The stateless system is a system that does not retain any information from the previous requests. This means that the system is reliable since there is no interconnection between the two requests.

### Main Points to Remember:

* It does not store any information between requests which makes it reliable.
    
* Since the information is not stored for stateless, we know this system is not complex to design and makes it easier to scale.
    
* Every request requires the user to send all the data which makes it cumbersome.
    
* Faster in nature since no data is stored.
    

## Stateful System

As the name suggests, the stateful system retains the information and stores session information.

### Main Points to Remember:

* Does store information.
    
* The system is complex to design and harder to scale.
    
* The user does not have to send all the data while making the request.
    
* Slower in nature
    

## Summary of the differences between Stateless and Stateful

| Feature | Stateless (REST APIs) | Stateful (Sessions) |
| --- | --- | --- |
| **Data Storage** | No previous request data is stored | Stores session data |
| **Scalability** | Easy to scale (each request is independent) | Harder to scale (session must be shared) |
| **Example** | RESTful APIs, microservices | Banking apps, shopping carts |
| **Performance** | Faster (no session management) | Slightly slower (session handling) |

Feature	Stateless (REST APIs)	Stateful (Sessions)
Data Storage	No previous request data is stored	Stores session data
Scalability	Easy to scale (each request is independent)	Harder to scale (session must be shared)
Example	RESTful APIs, microservices	Banking apps, shopping carts
Performance	Faster (no session management)	Slightly slower (session handling)
