Maintenance
Cloud hosted frends resources are updated in line with our release cycle.
For customers with hybrid configurations (Cloud and On-Prem Agents) we arrange a suitable time/date to update frends Core and Agents in order to synchronize the update of On-Prem resource.
Cloud Agent OS Updates/Security updates are kept in line with Microsoft’s Monthly patching cycle.
To avoid Agent downtime during patching we recommend using load balanced Agents in a high availability cluster for production environments.
