Part 3 – Adding Resilience and CloudFront

https://www.udemy.com/aws-certified-solutions-architect-associate/learn/v4/t/lecture/5028344?start=0

Backup our data to S3

aws s3 cp --recursive /var/www/html s3://data-bucket-name

Copy all media files to S3

aws s3 cp --recursive /var/www/html/wp-content/uploads s3://media-bucket-name

This command will re-copy every thing every time it is ran.  Better to use the sync command.

aws s3 sync --delete /var/www/html/wp-content/uploads s3://media-bucket-name

Create .htaccess rewrite rule

Options +FollowSymlinks
RewriteEngine on
rewriterule ^wp-content/uploads/(.*)$ http://d2lf6ybul99vzg.cloudfront.net/$1 [r=301,nc]
