1) If you plan to use TLS, you must create or import your certificate into Amazon Certificate Manager before launching Moodle.
2) Deploy the 00-master.yaml stack. **Do not enable session caching in ElastiCache and leave both the Min and Max Auto Scaling Group (ASG) size set to one.** The installation wizard will not complete if you have session caching configured.
3) After the stack deployment completes, navigate to the web site to complete the Moodle installation. *NOTE: You may encounter a 504 Gateway Timeout or CloudFront error on the final step of the installation wizard (after setting admin password).

3) After the stack deployment completes, navigate to the web site to complete the Moodle installation. *NOTE: You may encounter a 504 Gateway Timeout or CloudFront error on the final step of the installation wizard (after setting admin password). You can simply refresh the page to complete the installation.* You may also see "Installation must be finished from the original IP address, sorry." to solve this you will need to update your database and set the lastip field of the mdl_user table to the internal ip address of your ALB (you can find this by looking at the Network Interfaces from the EC2 page in the AWS Console). From the webserver you can run:
psql -h <hostname> -U<Username>
update mdl_user set lastip='<ip address>';
