Go language is popular: these well-known companies are using it

Go language has quickly been favored by many developers and companies since its release. Its simplicity, efficiency, and strong concurrency make it a high-profile programming language. . Not only that, more and more well-known companies have begun to use Go language to develop their software and services. This article will introduce some well-known companies using Go language and provide some specific code examples.

1. Google (Google): As one of the main developers of the Go language, Google naturally uses the Go language on a large scale internally. They use Go language for various projects including infrastructure, cloud services, web applications, etc. One of the famous projects is Kubernetes, an open source container orchestration system developed in Go language. The following is a simple Go code example showing how to write a simple HTTP server using the Go language:

package main

import (
    "fmt"
    "net/http"
)

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

    http.ListenAndServe(":8080", nil)
}

2. Amazon (Amazon): Amazon is also widely used in its cloud computing service AWS Go language. Some of their core services and tools are written in Go language, including AWS Lambda, AWS CLI, etc. The following is a simple Go code example that shows how to use the Go language to call AWS's S3 storage service:

package main

import (
    "fmt"
    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/s3"
)

func main() {
    sess := session.Must(session.NewSession())
    svc := s3.New(sess)

    params := &s3.ListBucketsInput{}
    resp, err := svc.ListBuckets(params)
    if err != nil {
        fmt.Println("Error listing buckets", err)
        return
    }

    for _, bucket := range resp.Buckets {
        fmt.Println(*bucket.Name)
    }
}

3. Apple (Apple): Apple has also begun to switch to using Go in recent years. Go language develops some back-end services and tools. They believe that the performance and maintainability of the Go language are excellent and suitable for building highly available systems. The following is a simple Go code example showing how to send emails using Go language:

package main

import (
    "fmt"
    "net/smtp"
)

func main() {
    from := "youremail@example.com"
    to := "recipient@example.com"
    msg := []byte("Subject: Hello, Go!

This is a test email from Go.")

    err := smtp.SendMail("smtp.example.com:25", nil, from, []string{to}, msg)
    if err != nil {
        fmt.Println("Error sending email", err)
        return
    }

    fmt.Println("Email sent successfully")
}

The above are just some well-known companies using Go language and some simple code examples. With the continuous development and improvement of Go language, I believe that more and more companies will choose Go language as their preferred development language, thus further promoting the popularity and development of Go language.
