NigelStratton-2251 Welcome to Microsoft Platform. Thankyou for posting your Query here.
In Azure, every VM – regardless if Linux or Windows – gets a temporary disk assigned automatically. This temporary disk is located on the physical server (the hypervisor) where the Azure VM is hosted and is non-persistent. Disks used by the operating system or additionally added data disks are persistent disks and stored in Azure Storage.
Assuming this is a classic IaaS VM, page file is by default set on the temporary storage for all the Azure Iaas VM's
For PaaS instances user will not have control over the OS configurations.
Hope this helps!
