Barracuda Networks and VMware vCloud Air - Better Flexibility Together

VMware vCloud Air is a public cloud platform built on the trusted foundation of vSphere; it's compatible with your on-premises virtualization deployments. This makes it easier to extend existing workloads to the cloud, and spin-up new application VMs. The point is, you have flexibility with VMware and Barracuda's product portfolio mirrors that flexibility. Our products can be deployed as a virtual appliance within your own data center or within vCloud Air. Our security and storage solutions can be configured wherever your workloads need protection and availability. There is no need to learn a new hypervisor to run our offerings or encounter new vulnerabilities because your storage and security solution is not cloud ready.
