A cloud stack is a collection of services and resources in your Amazon Web Services (AWS) account which holds all of the infrastructure needed to run your Moodle site.
A stack commonly consists of:
- Security groups 
- Network file system 
- EC2 web server instance 
- RDS database instance 
- Load balancer 
- TLS (SSL) security certificates 
There can be many more services and resources added to any given stack, so the list above is meant to provide a basic example for an average stack.
