Configuring AWS CloudFront is complicated. I find it useful to create a 'cheatsheet' of the steps and key values that I need to complete the configuration. As an example, assume I am transferring an existing https://subdomain.example.ca site to AWS serverless.
I run a number of Drupal, MediaWiki, and static websites on an AWS EC2 t2-micro server. The server Linux/Apache/MySQL/PHP stack is no longer supported, primarily because of conflicting server and Drupal requirements made upgrading difficult. My plan is to create static versions of the MediaWiki and Drupal sites.
