Elevated Productivity
OpenShift Virtualization offers organizations the opportunity to achieve operational savings by seamlessly managing both virtualized and containerized workloads. It leverages the same orchestration and clustering infrastructure provided by Red Hat OpenShift.
Deploying Virtual Machines (VMs) on OpenShift simplifies the integration of traditional server-based applications with modern cloud-native applications and their associated methodologies, including CI/CD, DevOps, and SRE. This integration allows organizations to benefit from accelerated time-to-market and other advantages of these practices, all without the necessity of initially redesigning virtualized workloads into container-native formats.
Personal Impact
Professionals will gain the ability to deploy and oversee virtualized workloads on OpenShift. They’ll manage these workloads using a blend of traditional methods, like SSH and Ansible, and contemporary DevOps practices such as GitOps and CI/CD
