With Ravello’s high-performance nested hypervisor, enterprises can run unmodified VMware, KVM and Hyper-V virtual machines on any public cloud (AWS, GCE, HP Cloud and Rackspace). In addition, Ravello has implemented software-defined networking, storage virtualization and various application services to automate the provisioning and deployment of enterprise applications in the cloud.
Consolidation in the context of virtualization means running multiple VMs on a single host machine to drive efficiency and cost reductions. With Ravello’s HVX hypervisor, which is designed to run in the cloud, the host is a virtual machine running in the public cloud and the guests are “nested” virtual machines.
Saving costs with nested virtualization
Since re-architecture or cloud migration for enterprise applications is very expensive and time-consuming, a nested virtualization solution, which allows existing enterprise applications to instantly use additional capacity from any public cloud, say for dev/test, is very cost-effective.
Resource consolidation can increase performance
There is more to consolidation than cost savings. In an experiment Ravello ran in the Amazon AWS cloud, the performance of four m1.small instances running with no nesting or consolidation was compared to that of running the same 4-VM application using one m1.large instance with four nested guests running on HVX. It was found that the larger instance had almost double the performance of the four small ones. Learn more. Performance can vary based on the underlying cloud and the nature of the actual application, but this experiment clearly demonstrates the unique possibilities with Ravello’s nested virtualization.
