Audience for this course

    • System administrators, platform operators, and cloud engineers.
    • Enterprise and cloud-native application developers.
    • Application and development infrastructure professionals such as site reliability engineers and DevOps engineers.

Prerequisites for this course

    • All students must be knowledgeable of Amazon Web Services (AWS), including operating and managing AWS compute, storage, and network resources.
    • For students that are new to Red Hat OpenShift it is recommended that you learn the fundamental skills of managing Red Hat OpenShift clusters, before taking DO120, from the following courses:
      • Red Hat OpenShift I: Containers & Kubernetes (DO180)
      • Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster (DO280)
    • Students with previous experience managing Kubernetes clusters are advised to take DO180 and DO280 before taking DO120 or at least acquire foundational skills operating Red Hat OpenShift clusters by using the following free resources from Red Hat:
      • Red Hat Developer Sandbox for OpenShift
      • OpenShift and Kubernetes learning from Red Hat Developer
      • Containers, Kubernetes and Red Hat OpenShift Technical Overview (DO080)

Technology considerations

    • Internet access is required to access AWS cloud services using the AWS console and the AWS CLI. It is also required to access the Red Hat Hybrid Cloud Console and associated Red Hat cloud services.
    • Students must possess an active AWS account with permission to activate services from the AWS Marketplace and an associated payment method for the AWS resources consumed by ROSA clusters.
    • Students must possess an active Red Hat customer portal account or a free Red Hat Developer program membership.

Impact on the organization

Red Hat® OpenShift® Service on AWS (ROSA) is a turnkey application platform that provides a managed Red Hat OpenShift service running natively on Amazon Web Services (AWS) 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 ROSA 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 of this training

After completing DO120, students can create ROSA 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.
