 ### Certificate provisioning
 We mentioned a 'provisioning agent', which is the entity that retrieves the certificate, inclusive of its private key, from the vault and installs it on to each of the hosts of the cluster. (Recall that Service Fabric does not provision certificates.) In our context, the cluster will be hosted on a collection of Azure VMs and/or virtual machine scale sets. In Azure, provisioning a certificate from a vault to a VM/VMSS can be achieved with the following mechanisms - assuming, as above, that the provisioning agent was previously granted 'get' permissions on the vault by the vault owner: 
   - ad-hoc: an operator retrieves the certificate from the vault (as pfx/PKCS #12 or pem) and installs it on each node
-  - as a virtual machine scale set 'secret' during deployment: the Compute service retrieves, using its first party identity on behalf of the operator, the certificate from a template-deployment-enabled vault and installs it on each node of the virtual machine scale set ([like so](../virtual-machine-scale-sets/virtual-machine-scale-sets-faq.yml#certificates)); note this allows the provisioning of versioned secrets only

   - using the [Key Vault VM extension](../virtual-machines/extensions/key-vault-windows.md); this allows the provisioning of certificates using version-less declarations, with periodic refreshing of observed certificates. In this case, the VM/VMSS is expected to have a [managed identity](../virtual-machines/security-policy.md#managed-identities-for-azure-resources), an identity that has been granted access to the vault(s) containing the observed certificates.

 The VMSS-/Compute-based provisioning presents security and availability advantages, but it also presents restrictions. It requires - by design - declaring certificates as versioned secrets, which makes it suitable only for clusters secured with certificates declared by thumbprint. In contrast, the Key Vault VM extension-based provisioning will always install the latest version of each observed certificate, which makes it suitable only for clusters secured with certificates declared by subject common name. To emphasize, do not use an autorefresh provisioning mechanism (such as the KVVM extension) for certificates declared by instance (that is, by thumbprint) - the risk of losing availability is considerable.
