OpenShift Virtualization

Transcript

1. OpenShift Virtualization An Established Hypervisor Alternative 1. What it is 2. History 3. Reference Customers 4. Migration Process & Team Enablement
2. 2 What is it / History
3. 3 A virtualization API and runtime for OpenShift, built on KubeVirt, to run and manage virtual machines using a Kubernetes-native way OpenShift Virtualization
4. 4 Red Hat OpenShift Virtualization A modern option for general purpose virtualization ▸ Unified platform for vms and containers ▸ Performance and stability of Linux, KVM, and qemu ▸ Includes Red Hat Enterprise Linux guest entitlements ▸ Supports Microsoft Windows guests through Microsoft SVVP Red Hat OpenShift Virtualization Red Hat OpenShift Red Hat Enterprise Linux Physical machine VMs Containers ▸ As-Is VM migration using Ansible Automation Platform + Migration Toolkit for Virtualization, Training and Consulting
5. It is about managing both VMs and containers 5 VMs have been built for decades, and they will not go away overnight. Virtual machines Containers solve certain use cases and will continue to rise, but some VMs will remain. Containers VMs and containers will be used to build applications, and some might even build on both. Applications
6. KVM-based (containerized) VMs 6 • KVM powers all Red Hat platforms ◦ KVM is a part of the Red Hat Enterprise Linux kernel • QEMU uses KVM to execute virtual machines • libvirt provides a management abstraction layer • Red Hat Virtualization, Red Hat OpenStack Platform, and OpenShift Virtualization all leverage KVM, QEMU, and libvirt HARDWARE RHCOS KVM CPU/RAM STORAGE NETWORK DRIVER DRIVER DRIVER OTHER APPS QEMU libvirt
7. For existing applications 7 Vintage applications in VMs can be taken to OpenShift as well By using infrastructure migration solutions, existing VM-based applications can be migrated as-is to OpenShift from VMware and other platforms. Lift and shift Existing – a decade old–Microsoft Windows VMs can be brought into OpenShift as-is today, and be refactored over time as needed. Windows apps in OpenShift now
8. Windows apps in OpenShift Windows VMs can be brought into OpenShift as-is (and maintained if they’re older), or refactored to use Windows Containers and Windows Server 2019 All applications - old and new - can benefit from a unified control and DevOps pipeline. Teams can choose the applications they want to refactor or containerize when the time is right. For application developers 8 Consistent developer experience (across VMs, containers, serverless) Refactor VMs on your schedule Unified tools, process and pipelines for all apps Application environments consist of VMs, containers, serverless and more. Development teams can now leverage the same tools, pipelines, and platform for building, managing and diagnosing issues with all apps.
9. For infrastructure owners 9 Modernize and simplify your datacenter Align your system administrators on one simpler architecture to manage and expose Consistency of management Focus your attention on maintaining the platform and it’s infrastructure. Workload related aspects are covered by developer self-service. Security is intrinsic and inherited from KVM. Focus on infrastructure and cluster operation
