#Create two workspaces - dev and prod
#terraform workspace new dev
#terraform workspace new prod

#Switch to a workspace
#terraform workspace select <workspace-name>

#List all workspaces
#terraform workspace list

#Delete a workspace
#terraform workspace delete <workspace-name>
#
#The advantage of using locals instead of variables is that locals can have
#logic inside them, instead of in the resource. Whereas variables only allows
#values and push the logic inside the resource.
