DO370 - Enterprise Kubernetes Storage with Red Hat OpenShift Data Foundation

Traditional storage options available to Kubernetes administrators are limited and lack flexibility and/or versatility. Red Hat OpenShift Data Foundation provides real advantages, even when it is backed by cloud storage such as AWS EBS and sophisticated on-prem legacy storage like SAN arrays. Many companies rely on third-party solutions to manage backup and disaster recovery in production. However, proper planning to implement these solutions requires knowledge of the Kubernetes CSI and OAPD APIs. This course walks the student through the recommended steps of configuring and managing storage services for container and Kubernetes services. Course content coverage Deploy Red Hat OpenShift Data Foundation in internal and external mode.  Provision non-shareable block storage to applications like databases.  Provision shareable block storage to applications like virtual machines.  Provision shareable file storage to such applications as CI/CD pipelines and AI/ML. Provision shareable object storage to applications, such as AI/ML and media streaming.  Provision storage for Red Hat OpenShift cluster services, such as monitoring and registry.  Monitor and expand storage capacity and performance. Attach and detach storage from an application for backup and archiving.  Create and access volume snapshots and clones.  Troubleshoot internal Ceph components of Red Hat OpenShift Data Foundation.  Perform backup and restore operations using the OADP API.

RH415 - Red Hat Security: Linux in Physical, Virtual and Cloud

Manage security of Red Hat Enterprise Linux systems deployed in bare-metal, virtual, and cloud environments. Red Hat Security: Linux in Physical, Virtual, and Cloud (RH415) is designed for security administrators and system administrators who need to manage the secure operation of servers running Red Hat® Enterprise Linux®, whether deployed on physical hardware, as virtual machines, or as cloud instances. This course is based on Red Hat Enterprise Linux 7.5, Red Hat Satellite 6.3, Red Hat Ansible® Engine 2.5, Red Hat Ansible Tower 3.2, and Red Hat Insights. Maintaining security of computing systems is a process of managing risk through the implementation of processes and standards backed by technologies and tools. In this course, you will learn about resources that can be used to help you implement and comply with your security requirements. Manage compliance with OpenSCAP. Enable SELinux on a server from a disabled state, perform basic analysis of the system policy, and mitigate risk with advanced SELinux techniques. Proactively identify and resolve issues with Red Hat Insights. Monitor activity and changes on a server with Linux Audit and AIDE. Protect data from compromise with USBGuard and storage encryption. Manage authentication controls with PAM. Manually apply provided Ansible Playbooks to automate mitigation of security and compliance issues. Scale OpenSCAP and Red Hat Insights management with Red Hat Satellite and Red Hat Ansible Tower.
