Amazon Web Service CloudFormation now supports Elastic Cloud Compute System Manager Parameter store and Parameterizing Configurations with StackSets Parameter overrides

Amazon Web Service CloudFormation now permits the users you to override parameter values by region and account in stack instances. Earlier the users could only make alternation to StackSets from the Original CloudFormation templates. You can now override the template parameter values when you first build the stack instances and you can also override parameter values for the existing stack instances that enable you to specify and customize stack instances that are based on your needs. Parameter section can be used in the CloudFormation template to enter custom values into the templates each time when the stack gets updated or when you build one.
