I am working on a SharePoint online project, and the current customer has an Azure VM to host the Remote Event Receivers and other SharePoint Apps. now in previous projects which i worked on, the customers use to have Azure subscriptions, where i can create a service bus as follow:-

Then inside my Provider Hosted app project, i can enter the service bus details as follow:-

this allowed me to debug my remote event receiver code. but as i mentioned before for the current project, the customer has an Azure VM, and not an Azure subscription, so is there a way i can create an Azure Service Bus inside Azure VM ?

If the answer, is No (i can not create a service bus inside Azure VM), then is there a way i can debug and test my Remote Event Receiver, without using Azure service BUS??

Thanks
