Could you explain the concept of distributed architecture and its main features?

Distributed architecture is a way of organizing a system where its components operate on different physical or virtual machines, interacting with each other over a network.

Main features:

• Scalability: new nodes can be added to increase performance.
• Fault tolerance: the system continues to operate even if one node fails.
• Load distribution: tasks are distributed among multiple servers.
• Responsibility separation: different services are responsible for different functions (microservices).

Example: in Java, you can use a microservice architecture with REST API, where each service is deployed separately and communicates via HTTP.

@RestController
public class UserController {
    @GetMapping("/users/{id}")
    public User getUser(@PathVariable String id) {
        // Retrieve user from database
    }
}

In such architecture, each service can be scaled and updated independently.
