+Azure VMware Solution continuously monitors the health of both the VMware components and underlay. When Azure VMware Solution detects a failure, it takes action to repair the failed components. When Azure VMware Solution detects a degradation or failure on an Azure VMware Solution node, it triggers the host remediation process.
 
 Host remediation involves replacing the faulty node with a new healthy node in the cluster. Then, when possible, the faulty host is placed in VMware vSphere maintenance mode. VMware vMotion moves the VMs off the faulty host to other available servers in the cluster, potentially allowing zero downtime for live migration of workloads. If the faulty host can't be placed in maintenance mode, the host is removed from the cluster.
 
 > [!TIP]
-> Customer communication: An email is sent to the customer's email address before the replacement is initiated and again after the replacement is successful. To receive emails related to host replacement, you need to be added to any of the following Azure RBAC roles for subscription: 'ServiceAdmin', 'CoAdmin', 'Owner', 'Contributor'.
