Create AWS Users
Sign in Amazon Web Services (AWS) account
Navigate to the IAM Users page in the AWS Console
Create Access Keys
Now, it’s time to edit the wp-config.php
Find this line:
/* Add any custom values between this line and the "stop editing" line. */
/* That's all, stop editing! Happy publishing. */
Insert the info between the above lines:
define( 'AS3CF_SETTINGS', serialize( array(
'provider' => 'aws',
'access-key-id' => '********************',
'secret-access-key' => '**************************************',
) ) );
Create a New S3 Bucket
Setup Cloudfront CDN
