Maintaining network resiliency and session survivability for SD-WAN in public cloud deployments presents unique challenges, often leading to service disruptions during a device failure. To address this, Palo Alto Networks now supports high availability (HA) for SD-WAN on VM-Series next-generation firewalls in public cloud environments.

This feature enables an active/passive HA configuration that uses a floating IP address to ensure seamless failover between firewalls. By maintaining session state during a failover event, it minimizes downtime and preserves application performance for your users. This allows you to build resilient and reliable SD-WAN architectures in the cloud, mirroring the high availability standards traditionally found in on-premises deployments.

This HA capability is available for VM-Series firewalls in AWS and Microsoft Azure.
