How do I run an Azure Service Bus Topics subscriber app 24/7 in Azure?

There is an example here that explains on how to send messages and receive messages using Azure Service Bus through a publisher and subscriber application.

My questions are about the subscriber application that receives messages:

  1. Does registering in the application a message handler with subscriptionClient.RegisterMessageHandler(ProcessMessagesAsync, messageHandlerOptions); process the messages 24/7 until the application is shut down?
  2. Can I deploy the subscriber console app in Azure only through Docker Container? If I don't want to use containers, what is the other hosting option I have? I have done CI/CD pipeline to host a WebAPI in Azure App Services from Visual Studio 2019 before.

That's correct. That API is intended for the continuous flow of messages that needs to be processed.

You can host continuously running Azure Service Bus processing using the following options:

  • Virtual Machine(s)
  • AKS/ACI
  • Service Fabric
  • Azure WebJobs (requires a WebApp)

An alternative option would be to look into Azure Functions. While it doesn't run 24/7, it allows a reactive type of application.
