I have seen a number of posts on this topic, many old, including; https://moodle.org/mod/forum/discuss.php?d=254113 which provides some hints at best.
My issues is latency as I have customers around the world, and HA would be a "nice to have" as well.
Has anyone documented the architecture of a successful deployment of Moodle on AWS using EC2 web server(s) in different Regions with global load balancer and a single database instance. I can come up with a half dozen different ways to do this, but am looking for some guidance on a production deployment. Following these basic instructions for a single instance, I presume you can swap out "mysql" with one of the AWS database services like RDS. I'm looking for detail, for example how you setup config.php and the AWS services to match. I've seen everything from nfs mounts to remote mysql described, however I suspect going "native" with AWS will work out better in the long run.
Many thanks in advance,
