@jill - While preparing for this I a major cleanup of our Amazon AWS environment:

• Removed the old database cluster from Amazon AWS RDS. The cluster was no longer a "real cluster", had only one database service (server) (minimum for a cluster is two servers) and we are paying extra for a cluster that we are not really using. High availability and high performance is no longer that important. It was also beefed up to be able to fuction as a fallback backend for ELMCIP. The ELMCIP infrastructure (NIRD) had couple of rough years with a lot of downtime due to hardware problem but have for the last couple of years been OK.
• Created a new stand alone Mariadb server in Amazon RDS and copied db. to this and updated all Drupal settings.
• Removed all unused EC2 storage block storage.
• Upgraded block storage in use to newer storage types.
• Backup: We used to create db. snapshots every 30 minute building the site to allow us to only roll back the latest db. snapshot should we do a mistake updating/building the site. No longer needed though we still create daily backups. This also reduces database traffic and save costs.
• Reduced how often Drupal maintenance tasks run. Save CPU and DB costs.

Removed PHP 7.4 and install PHP 8.0. Compiled up apcu and uploadprogress. Reboot and still works OK. Closing
