VNS3 is a hybrid overlay networking appliance.
VNS3 lets customers extend their network to the cloud. Customers can manage cloud-based servers as if they are running in on-premise data centers. Customers can distribute a VNS3 network across multiple public and private clouds to create hybrid cloud networks.
VNS3 acts as six devices in one: router, switch, firewall, VPN concentrator, protocol redistributor and scriptable SDN.
VNS3 is different from other SDN and network function virtualization (NFV) solutions by creating a customer-controlled overlay network on top of the underlying network backbone.
Since its launch, VNS3 has secured over 80M virtual device hours in public and private clouds. VNS3 is available for Public Clouds, Private Clouds, Hybrid Clouds, and Virtual environments.
