Overview
Learn how to deploy, access, and perform basic customizations to a ROSA cluster.
This course teaches Platform Operators how to provision managed clusters by using Red Hat OpenShift Service on AWS (ROSA) and how to perform basic day-2 customizations on these clusters to onboard application developers and applications.
Following course completion, you will receive a 45-day extended access to hands-on labs for any course that includes a virtual environment.
Skills Covered
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.
Prerequisites
- 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:
- 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:
Target Audience
- System administrators, platform operators, and cloud engineers.
- Enterprise and cloud-native application developers.
