AWS KVM adoption and Nutanix AHV
Nutanix, which strives to bring the best of public cloud to the on-prem data center, has long incorporated AWS innovations as part of its enterprise cloud strategy. Nutanix diverged from the public cloud leader, though, in hypervisor selection and launched its own customized KVM hypervisor, AHV, almost two and a half years ago. AWS recently revealed an upcoming migration from Xen to KVM which, along with current utilization by Google Cloud Platform, brings added weight to the concept of KVM as cloud hypervisor standard.
AHV – The Enterprise Cloud Hypervisor
AHV is taking the enterprise by storm: As of the end of the 2017 fiscal year, 24% of Nutanix nodes were running its hypervisor. And it is not just customers who are embracing it: AHV is now supported by industry leaders such as SAP, Arista, Epic Hyperspace, Brocade, Commvault, Veeam, Veritas, and scores of others. Even Microsoft and Citrix, who both have their own hypervisors, support all of their products on AHV. Comtrade Software wrote its backup solution, HYCU, specifically for AHV.
When virtualization first became popular in the early 2000’s, infrastructure storage area network (SAN) services were required to enable vMotion and live migration. The hypervisors were necessarily complex in order to provide functionality that was only later off-loaded to “virtualization aware” storage, shifting that complexity to the storage system. Nutanix negated the need for complex hypervisors and virtualization aware storage by processing all of the data services where they belong – natively in the hyperconverged infrastructure (HCI) storage layer. Nutanix built AHV to take advantage of HCI by dramatically simplifying KVM and integrating it into its Prism management, while also hardening the hypervisor to meet enterprise security requirements.
AHV is the only hypervisor purpose-built for hyperconverged infrastructure and a scale-out enterprise cloud using the same web-scale principals that power the distributed storage in Nutanix’s HCI offering. Add a Nutanix node to the cluster, and you’ve automatically extended the virtualization which is managed from the same Prism management plane. Should a node fail, the Acropolis Distributed Storage Fabric (ADSF) automatically self-heals for availability and impacted VMs are restarted on other nodes.
