Issuing the poweroff command within Vyatta NOS does not deallocate the Vyatta NOS VM, and you continue to be charged. If you have finished using a router instance temporarily, you can deallocate the instance, while allowing it to be resumed later by using the azure vm deallocate <resource-group> <name> command as follows:

$ azure vm deallocate vRouter vRouter1 info:	Executing command vm deallocate
+ Looking up the VM "vRouter1"

+ Deallocating the virtual machine "vRouter1" info:	vm deallocate command OK

To bring a deallocated Vyatta NOS VM back up, use the azure vm start <resource-group> <name> command as follows.

$ azure vm start vRouter vRouter1 info:	Executing command vm start
+ Looking up the VM "vRouter1"

+ Starting the virtual machine "vRouter1" info:	vm start command OK

If you have finished using a router instance permanently, you can delete it by using the azure vm delete <resource-group> <name> command as follows.

$ azure vm delete vRouter vRouter1 info:	Executing command vm delete
+ Looking up the VM "vRouter1"

Delete the virtual machine "vRouter1"? [y/n] y
+ Deleting the virtual machine "vRouter1" info:	vm delete command OK
