DEPLOYING OPENSTACK WITH MULTI-HYPERVISOR ENVIRONMENT
With Openstack gaining lot of momentum, each of its releases is able to address some unanswered questions. One of the many questions that enterprises or service providers ask is “Can Openstack work on Multi-hypervisor?”
The answer is YES. It DOES!
Before jumping right on how to set multi-hypervisor environment using Openstack, one should know what is “multi-hypervisor environment”?
What is multi-hypervisor environment?
For many organisations, a single hypervisor simply isn’t the right answer for all of their virtualization needs, and those businesses may choose to adopt a second hypervisor product as a complement to the first. When the subject of adding a second hypervisor comes up, it’s often because virtualization licensing costs are getting out of hand or because IT wants to avoid vendor lock-in. Or, it could be that the existing hypervisor isn’t offering all the features the business needs. As server virtualization has matured, multi-hypervisor environments have become more common. But adding a second virtualization platform to the Openstack cloud environment requires solid justifications and carries challenges that must be considered carefully before incorporating yet another layer of complexity to the environment.
Why we need multi-hypervisor environment?
Most OpenStack distributions are centred around KVM hypervisor. However Enterprises, on the other hand, have massive investments in a variety of different virtualization platforms such as Xen, ESXi etc. Most large enterprises are unwilling to lose their existing capability with their chosen hypervisor at the same time. This provides a solid use case for Openstack community to ensure it supports multi-hypervisor environment.
What are the hypervisors that Openstack support?
OpenStack Compute supports many hypervisors, which might make it difficult for you to choose one. Most installations use only one hypervisor.
