Course Overview
Learn how to deploy, access, and perform day-to-day operations to a ROSA cluster.
Who should attend
Primary:
- ROSA administrators
- System administrators, platform engineers, cloud engineers, other infrastructure-related IT roles who are responsible for providing and supporting infrastructure for applications deployed on AWS.
Secondary:
- Enterprise architects
- Application and development infrastructure professionals such as site reliability engineers and DevOps engineers.
Prerequisites
- All students must be knowledgeable about Amazon Web Services (AWS), including operating and managing AWS compute, storage, and network resources
- For students who are new to Red Hat OpenShift, it is recommended that you learn the fundamental skills of managing Red Hat OpenShift clusters from the following courses:
- Students with previous experience of managing Kubernetes clusters are advised to take DO180 and DO280 or at least to acquire foundational skills in 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
- !
Course Objectives
Impact on the Organization
- Red Hat OpenShift Service on AWS (ROSA) is a turnkey application platform that provides a managed Red Hat OpenShift service that runs natively on Amazon Web Services (AWS) to enable 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-premise and cloud environments. Organizations that use ROSA follow the same operational processes as on a self-managed Red Hat OpenShift Container Platform cluster in their on-premise data centers, and deploy the same applications on any OpenShift cluster, whether a managed cluster or a self-managed one
Impact on the Individual
- After completing CS120, 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
Course Content
This course teaches IT operations staff how to deploy a public Red Hat OpenShift Service on AWS (ROSA) cluster for experimentation and to provision projects for development teams to work within. IT operations staff will learn how to perform day-to-day operation of ROSA clusters and support application teams which use that cluster. IT operations staff can then apply the same skills and similar procedures to private ROSA clusters of their organizations.
