Static SSM Parameter Names

[salmanap]

The SSM parameter names are static. If i try to deploy a new stack with a different name, the new stack fails to create because CFN complains that the parameter names already exist

The SSM parameter names include the value of the Stage parameter passed into each template. So you can deploy multiple stacks to the same account/region as long as each stack has a unique Stage parameter value.
