Virtual edge gateways must be deployed across multiple hypervisor hosts.

Description

<VulnDiscussion>An edge gateway is deployed to allow north-south traffic to flow between the virtualized network and the physical network, including destinations outside of the data center or enclave boundaries. The gateway can also filter the north-south traffic to enforce security policies for communication between the physical and virtual workloads. If the edge gateways deployed as virtual machines are resident on the same host, the host becomes a single point of failure for all communication between the virtual workload and the physical network infrastructure. Deploying the edge gateways across multiple hypervisor hosts eliminates the risk of a single point of failure, thereby ensuring there is always reachability between virtual machines and the physical network infrastructure and reducing the risk of black-holing north-south traffic.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
