We are migrating our Magento 1.9 to AWS. We have already implemented an RDS MySQL database, an EFS for static and PHP files. Alsa with we has a load balancer connected with for the moment 2 servers EC2. My question is about the cron job on Magento.
Is there any way to use launch cron on my infra? My both EC2 are the same and I don't want to select a master just for my jobs. If there is a failover, I want my job is still running. If I decide to put my cron in my both server, is it any risk that a task runs twice at the same time?
Also, if you are using elasticache, should I have an S3 or does it work with an EFS also?
Thanks a lot Thomas
