Red Hat Virtualization: Bridging the Gap with the Cloud and Hyperconverged Infrastructure
Red Hat Virtualization offers a flexible technology for high-intensive performance and secure workloads. Red Hat Virtualization 4.0 introduced new features that enable customers to further extend the use case of traditional virtualization in hybrid cloud environments. The platform now easily incorporates third party network providers into the existing environment along with other technologies found in next generation cloud platforms such as Red Hat OpenStack Platform and Red Hat Enterprise Linux Atomic Host. Additionally, new infrastructure models are now supported including selected support for hyperconverged infrastructure; the native integration of compute and storage across a cluster of hosts in a Red Hat Virtualization environment.
The deep integrations allow flexibility when deploying diverse workloads and scheduling them to run on the right platforms. Traditional applications can be scheduled to run in Red Hat Virtualization while cloud-native applications can be executed in Red Hat OpenStack Platform, which is purpose-built for cloud workloads. Since the same KVM hypervisor is used in both environments, as well as the same virtual machine image format; a set of common templates or images can be provided to both environments. This structure reduces complexity and increases efficiency in a hybrid cloud environment by decreasing the number of templates that have to be maintained.
In cloud environments, images will most likely utilize cloud-init, a service that provides boot time customization for cloud and virtualization instances. This deployment allows different aspects of the virtual machines, such as hostname, network settings, and authentication methods to be configured while the VM is being deployed. Red Hat Virtualization supports the cloud-init service, so that cloud images can be deployed and customized in Red Hat Virtualization the same way they are supported in an OpenStack cloud. Users gain flexibility by being able to use the same cloud-init scripts in a Red Hat Virtualization environment as they would in an OpenStack-based cloud environment to complete the initial configuration of their virtual machine workloads.
