Have you had experience working with distributed transactions in microservice architecture?

Yes, experience with service and service-oriented architecture includes creating and maintaining applications broken down into independent services that interact with each other through well-defined interfaces (e.g., REST API or gRPC).

Service-oriented architecture allows:

• Improved scalability, as each service can be scaled independently.
• Increased fault tolerance, since a failure of one service does not bring down the entire system.
• Easier maintenance and development by dividing responsibilities among teams.

Example: In Java, you can implement a microservice using Spring Boot, which provides a REST API for specific business logic.

@RestController
public class UserService {
    @GetMapping("/users/{id}")
    public User getUser(@PathVariable String id) {
        // Logic to retrieve user
        return userRepository.findById(id);
    }
}

Such a service can interact with other services via HTTP requests, ensuring modularity and system flexibility.
