Impact on the organization
Microsoft Azure Red Hat® OpenShift® is a turnkey application platform that provides highly available, fully managed Red Hat OpenShift clusters on demand. Red Hat and Microsoft jointly engineer, manage, and support the platform, allowing organizations to increase operational efficiency, refocus on innovation, and quickly build, deploy and scale applications.
Red Hat OpenShift is the hybrid cloud platform that brings operational consistency to on-premises and cloud environments. Organizations using Microsoft Azure Red Hat OpenShift follow the same operational processes used by a self-managed Red Hat OpenShift Container Platform on their on premises data centers and deploy the same applications on any OpenShift cluster, be it a managed cluster or a self-managed one.
Impact on the Individual
After completing DO121, students can create Microsoft Azure Red Hat OpenShift clusters. Most day-to-day application and cluster administration tasks are performed the same way across Red Hat OpenShift products, so IT professionals apply the same skills in managing Red Hat OpenShift clusters to both cloud and on-premise environments.
