• Leaves NodeJS for Golang
• Creates Apex business

Apex

• Talked about Apex before...
• Apex Up is API gateway integration
• Proxies and hides AWS complexity of API GW
• Can be used for static content
• Agnostic really; Node.js, Python, Crystal

A Golang Web service

package main

import (
    "fmt"
    "log"
    "net/http"
    "os"
)

func main() {
    addr := ":" + os.Getenv("PORT")
    http.HandleFunc("/", hello)
    log.Fatal(http.ListenAndServe(addr, nil))
}

func hello(w http.ResponseWriter, r *http.Request) {
    fmt.Fprintln(w, "Hello World from Go")
}

Up golang- Examples

Assuming you have an AWS profile setup ..

Let's iterate with Gin

Gin - Live reload utility for Go web servers

Further examples

• github.com/kaihendry/lk
• github.com/apex/gh-polls

Other icing on the cake

• Multi region deployments
• Powerful logging (CloudWatch filtering)
• make / hooks support

To conclude

Welcome to the next generation
