You are developing an Azure Service application that processes queue data when it receives a message from a mobile application. Messages may not be sent to the service consistently.
You have the following requirements:
✑ Queue size must not grow larger than 80 gigabytes (GB).
✑ Use first-in-first-out (FIFO) ordering of messages.
✑ Minimize Azure costs.
You need to implement the messaging solution.
