@Sudha P - Thanks for reaching out and for being patient .
cloudName represents the Azure cloud you're connecting to.
AzureCloud is the value for the Azure public cloud, which is the default value if the value is omitted. Other options are AzureUSGovernment and AzureChinaCloud. Note that the Azure Portal automatically puts in the correct value when you generate a script there.
Hope that helps.
