Go 언어는 어떤 분야에서 장점이 있고, 개발에는 어떤 소프트웨어가 적합한가요?

package main

import (
    "fmt"
    "net/http"
)

func handler(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintf(w, "Hello, World!")
}

func main() {
    http.HandleFunc("/", handler)
    http.ListenAndServe(":8080", nil)
}

package main

import (
    "fmt"
    "net"
)

func main() {
    ln, err := net.Listen("tcp", ":8080")
    if err != nil {
        fmt.Println("Error listening:", err.Error())
        return
    }
    defer ln.Close()

    fmt.Println("Server listening on port 8080")

    for {
        conn, err := ln.Accept()
        if err != nil {
            fmt.Println("Error accepting connection:", err.Error())
            continue
        }
        go handleConnection(conn)
    }
}

func handleConnection(conn net.Conn) {
    defer conn.Close()
    // 处理连接
}

package main

import (
    "fmt"
    "log"

    "go.etcd.io/etcd/clientv3"
)

func main() {
    cli, err := clientv3.New(clientv3.Config{
        Endpoints:   []string{"localhost:2379"},
        DialTimeout: 5 * time.Second,
    })
    if err != nil {
        log.Fatal(err)
    }
    defer cli.Close()

    fmt.Println("Connected to etcd server")

    // 使用etcd进行分布式服务发现和配置管理
}
