Azure requirements can differ from the ESX/Hyper-V ones. Please take a look into the ClearPass documentation.

Subject: Confusion about Azure Clearpass vCPU requirements
I am confused about the CPU requirements for running a Clearpass C1000V model. When checking the hyperv/ESX requirements for a C1000V we see the following:
C1000V (500 Virtual Appliance OVF)
- 8 reserved virtual CPUs - Underlying CPU is recommended to have a PassMark® of 3000 or higher
- 8 GB RAM
However, when deploying a 6.12 Clearpass from the Azure Marketplace from HPE, we see a recommended Standard_D2s_v3 with 2 vcpus, 8 Gib memory and that corresponds to a ClearPass C1000 appliance. We are running a few CPPM's in Azure with those hardware specs and we see performance issues on the CPU load.
Am i wrong to expect at least 8 vcpu's in Azure?
