How did you implement microservices architecture in your last project?

In my last project, the microservices architecture was implemented using Spring Boot and Spring Cloud. Each microservice was a separate application with a clearly defined responsibility area. Communication between services used REST API with JSON.

Main implementation points:

• Service registration and discovery via Eureka, which allowed dynamic service address discovery.
• Load balancing with Ribbon.
• Centralized configuration through Spring Cloud Config.
• Failure handling using Hystrix to implement the Circuit Breaker pattern.

Example of a simple REST controller of a microservice on Spring Boot:

@RestController
@RequestMapping("/users")
public class UserController {
    @GetMapping("/{id}")
    public User getUser(@PathVariable String id) {
        // logic to get user
        return userService.findById(id);
    }
}

Thus, each service was independent, easily scalable, and updatable without affecting other system components.
