golang框架中如何实现分布式系统设计的最佳方法是什么？

// server.go
package main

import (
    "context"
    "fmt"
    "net"
    "io"

    "google.golang.org/grpc"
    pb "github.com/example/grpc/helloworld"
)

type helloworldServer struct{}

func (s *helloworldServer) SayHello(ctx context.Context, in *pb.HelloRequest) (*pb.HelloResponse, error) {
    return &pb.HelloResponse{Message: "Hello " + in.GetName()}, nil
}

func main() {
    lis, err := net.Listen("tcp", ":50051")
    if err != nil {
        log.Fatalf("failed to listen: %v", err)
    }
    s := grpc.NewServer()
    pb.RegisterGreeterServer(s, &helloworldServer{})
    log.Printf("server listening at %v", lis.Addr())
    if err := s.Serve(lis); err != nil {
        log.Fatalf("failed to serve: %v", err)
    }
}

// client.go
package main

import (
    "context"
    "fmt"
    "os"

    "google.golang.org/grpc"
    pb "github.com/example/grpc/helloworld"
)

func main() {
    name := "John Doe"
    // Parse command-line argument if provided.
    if len(os.Args) > 1 {
        name = os.Args[1]
    }
    conn, err := grpc.Dial("localhost:50051", grpc.WithInsecure())
    if err != nil {
        log.Fatalf("did not connect: %v", err)
    }
    defer conn.Close()
    c := pb.NewGreeterClient(conn)
    r, err := c.SayHello(context.Background(), &pb.HelloRequest{Name: name})
    if err != nil {
        log.Fatalf("could not greet: %v", err)
    }
    fmt.Println(r.GetMessage())
}
