AWS EKS Mendix Reference Deployment

We have used this as a starting point. It setups a private cloud infrastructure in your AWS Account identified by your access and secret key and sets up a basic EKS cluster with 2 or 3 EC2s and you can experience and manage everything about your mendix app from Mendix Developer portal.

Basics of terraform and aws cloud knowledge is enough to run this as is. If you want any customizations, use chatgpt and paste the github link or the script files to make more modifications or better if you involve a devops resource in your team for any complex modifications
