I am in the process of setting up a simple Moodle cluster on AWS for production use. The plan is to use a loadblancer, two EC2 instances and a RDS. I have worked extensively with Moodle before but have never set it up on AWS before.
I am a little bit confused about where to put my moodledata directory as I will need to read/write to this directory from multiple EC2 instances. I see that EFS is the best option but apparently it is not available in Frankfurt(which is the region I have to use). Will I have to use S3? Or are there better options out there?
