Your system is quite complicated for users, it needs simple usage and clearer instructions. For example, when a user wants to delete a VPS service, he only needs one command to delete all services related to that VPS, avoid the service that works and incur costs for the user that they do not want. I am the first time to use azure's service, when deleting VPS, I just went to delete in Virtual machines, I thought that so I stopped the service and did not have to pay for usage anymore, but no, I was charged. Because there are a lot of things that haven't been deleted, which annoys users like me because I have to pay for what I don't use.
