Select two benefits of deploying SD-WAN controllers in cloud-hosted services.

Deploying SD-WAN controllers in cloud-hosted services like AWS or Azure significantly accelerates deployment because it eliminates the need for physical hardware procurement, installation, and initial configuration. Cloud providers offer instant provisioning of virtual machines, allowing quick setup of the vManage, vSmart, and vBond controllers. Furthermore, cloud deployments inherently support high availability and disaster recovery by allowing controllers to be easily installed across multiple cloud regions (e.g., primary in us-east-1, backup in us-west-2). This geo-redundancy ensures business continuity in case of a regional outage. While cloud services do utilize well-known platforms, this is a characteristic, not a direct benefit of the deployment model itself. Integrating WAN Edge devices into the cloud is a separate functionality (cloud on-ramp), not a benefit of controller hosting. Controllers do not automatically implement zone-based firewalling; that is a function of the WAN Edge devices or security services.
