// dns有差，會比較慢

// route53 // 已經有用apex domain name取名的SOA record // 而且route53不像一般DNS使用@代表apex domain // 所以當我需要設定 apex domain指向時 // 會造成record conflict

先把External nameserver轉移到Route53 再去amplify console設定custom domain 會自動把apex domain加進route53 record不用自己設

amplify

amplify作的事，把github source code拉下來，跑gatsby build再放到s3，更新cloudfront dist

所以不需要自己先build再push，git repo也不需要放public asset
