CloudFormation allows us to quickly and easily deploy your infrastructure resources and applications on AWS.
We can either 'Create New Stack' ( if we do not have any stacks ) or 'Launch CloudFormer' if a Stack is already available.
The use of services such as CloudFormation, ElasticBealStalk and AutoScaling are free, we are actually paying for the resources these services create
To get the attribute name we use the function Fn::GetAtt for the value in the outputs tag will return the name of the attribute specified.
If there is an error in the script CloudFormation will automatically roll back all the resources that were created.
Rollback is enabled by default.
