Red Hat OpenShift Administration II: Operating a Production Kubernetes Cluster with exam (DO281) prepares OpenShift Cluster Administrators to perform daily administration tasks on clusters that host applications provided by internal teams and external vendors, enable self-service for cluster users with different roles, and deploy applications that require special permissions such as such as CI/CD tooling, performance monitoring, and security scanners. This course focuses on configuring multi-tenancy and security features of OpenShift as well as managing OpenShift add-ons based on operators.
The skills you learn in this course can be applied using all versions of OpenShift, including Red Hat OpenShift on AWS (ROSA), Azure Red Hat OpenShift, and OpenShift Container Platform.

The minimum required prerequisites for successfully undertaking the DO281 Red Hat OpenShift Administration II: Configuring a Production Cluster with Exam course are as follows:
These prerequisites ensure that students have the essential skills and understanding to effectively engage with the course material and succeed in configuring and managing OpenShift clusters.
Brief Introduction:
The DO281 Red Hat OpenShift Administration II course prepares administrators to efficiently manage, secure, and scale OpenShift clusters in production environments.
Job Roles and Audience:
The DO281 Red Hat OpenShift Administration II: Configuring a Production Cluster with Exam course equips administrators with the skills to configure, manage, and secure OpenShift clusters, ensuring reliable operation across various development teams and applications.
Security features in technology involve mechanisms designed to protect systems and data from unauthorized access, attacks, and damage. These features include encryption, which scrambles data so it can't be read without a key; firewalls, that block unauthorized access to networks; and authentication protocols ensuring that only legitimate users can access the system. Regular updates and patches further secure systems from newly discovered vulnerabilities. For Openshift administrators using DO280 Red Hat courses, it's crucial to understand how to implement and manage these security aspects effectively within an OpenShift environment to maintain data integrity and prevent breaches.
Multi-tenancy is a software architecture where a single instance of an application serves multiple users or tenants. Each tenant's data is isolated and remains invisible to other tenants. This model is cost-effective and efficient, allowing for shared resources like storage and memory but maintaining privacy and security for each user group. It's often used in cloud platforms, such as Red Hat's OpenShift, where administrators manage and deploy containerized applications efficiently. Multi-tenancy maximizes resource utilization and simplifies updates, making it ideal for businesses looking to scale operations without compromising on service delivery to users.
OpenShift add-ons management involves enhancing the capabilities of the OpenShift platform by integrating additional features and services. These add-ons can range from networking components and storage solutions to monitoring tools and developer utilities. Administrators use them to tailor the environment to meet specific organizational needs, ensuring that applications run smoothly and efficiently. By managing add-ons properly, OpenShift administrators can optimize their clusters, maintain robust security, and improve overall performance, thereby enhancing the deployment and management of containerized applications. Proper add-on management is essential for maximizing the platform's functionality and adaptability to various workloads.
Declarative resource management involves defining the desired state of your system resources using a high-level configuration language, rather than programming exact steps to achieve it. This approach, prominent in tools like Kubernetes, which is utilized extensively in OpenShift, automates the process of deploying, maintaining, and scaling applications. By focusing on the "what" rather than the "how," it simplifies the administrator's tasks, making systems easier to manage and more consistent. Specifically, in the context of OpenShift, a platform for container orchestration, roles like an OpenShift administrator benefit from this methodology by ensuring applications run predictably across different environments.
Deploying packaged applications involves installing and configuring pre-built software into a computing environment. This is commonly done in enterprise settings using platforms like Red Hat OpenShift. As an OpenShift administrator, you manage these deployments on the platform, ensuring that applications are correctly set up and run efficiently. The process streamlines by automating repetitive tasks, providing a stable and scalable environment for the applications, and enabling the fine-tuning of configurations to meet specific organizational needs. This method enhances productivity and reduces deployment errors, making it valuable for maintaining robust enterprise systems.
Configuring authentication in an IT system, like when managing OpenShift through courses like DO280, involves setting up and verifying the identity of users or systems before allowing access to data and applications. This is crucial for maintaining the security and integrity of the system. As an OpenShift Administrator, one must establish rules and processes that determine who can access different levels of information and functionality, ensuring that only authorized users can perform specific actions on the network. Effective authentication helps in protecting against unauthorized access and potential breaches.
Network security involves protecting a computer network from intruders, whether targeted attackers or opportunistic malware. It includes both hardware and software technologies. Effective network security manages access to the network, incorporating multiple layers of defenses at the edge and in the network. Each network security layer implements policies and controls, allowing only authorized users to access network resources and blocking malicious actors from executing threats and exploitations. As organizations increasingly adopt cloud solutions like OpenShift, admins must ensure these environments are also secure, by applying comprehensive security measures that adhere to industry best practices.
OpenShift Container Platform is a robust system designed for deploying and managing containerized applications, primarily using Docker containers and orchestrated through Kubernetes. It assists in automating the setup, scaling, and operations of applications across various environments. It is particularly relevant for "OpenShift administrators" who utilize courses like the DO280 to master skills including setup, managing, and troubleshooting. This platform supports multiple programming languages and integrates with various tools, enhancing the way teams develop, test, and deliver software without a heavy reliance on hardware.
