Advantages:

Reduced network calls & latency

Aggregator acts like a facade & hides the backend complexity.

Spring WebFlux & Spring WebClient would be a perfect choice here to build this aggregator service for making these calls in a non-blocking way to utilize the system resources efficiently.

@Service
public class ProductClient {

    private final WebClient client;

    public ProductClient(WebClient.Builder builder) {
        this.client = builder.baseUrl("http://localhost:3000/products/").build();
    }

    public Mono<Product> getProduct(Integer productId){
        return this.client
                .get()
                .uri("{productId}", productId)
                .retrieve()
                .bodyToMono(Product.class)
                .onErrorResume(ex -> Mono.empty()); // switch it to empty in case of error
    }

}
