Learning Objectives and Outcomes:
Red Hat OpenShift is a comprehensive platform that simplifies the development, deployment, and scaling of applications. It’s built on container technology, specifically using OpenShift Container Engine, which allows developers to package and run applications reliably across diverse environments. OpenShift also supports on-prem deployment (openshift on prem), giving businesses control over hosting their applications on their own infrastructure. Red Hat offers training for specific OpenShift skills through courses like DO180 OpenShift (redhat do180) and DO280 (red hat do280), enhancing proficiency in using this platform for real-world application scenarios.
Bare metal refers to the physical hardware of a computer system, without any operating system or software installed. In the context of IT and data centers, a bare metal server is a single-tenant physical server. This is in contrast to virtualized servers, where multiple virtual machines share the same physical hardware. Bare metal servers are used for performance-intensive applications because they allow the user full control over the hardware, leading to higher efficiency and performance due to the lack of overhead from a hypervisor layer. They are also chosen for their enhanced security and predictability compared to cloud environments.
KVM (Kernel-based Virtual Machine) infrastructure is a virtualization solution for Linux that turns it into a hypervisor, allowing a host machine to manage multiple, isolated virtual environments called guest machines. Each guest can run their own operating system independently. KVM leverages the hardware's acceleration features to run guests efficiently, making it suitable for managing complex workloads and providing a robust platform for data centers. By converting Linux into a hypervisor, KVM helps utilize the hardware directly, offering a scalable and secure environment for deploying applications, enhancing performance, and optimizing resource use.
DNS, or Domain Name System, is like an internet phonebook that helps computers translate the names of websites into numbers (IP addresses) so they can find and communicate with each other. Whenever you type a website name like "google.com," DNS servers look up that address to find its corresponding IP address, directing your internet request accurately. This system is crucial for ensuring that the internet is not only user-friendly but also operates smoothly, allowing for quick and efficient data access and communication over networks.
DHCP, or Dynamic Host Configuration Protocol, is a network management protocol used to automatically assign IP addresses and other communication parameters to devices connected to a network, enabling them to communicate effectively. This automatic assignment saves administrators from having to manually assign addresses individually and helps manage address configurations in large networks efficiently. DHCP dynamically distributes network configuration details, such as IP addresses, subnet masks, and default gateways, ensuring devices can connect to the network smoothly and with minimal conflict. This makes DHCP essential in maintaining organized and fluid network operations.
Apache is a popular web server software that allows websites to be accessible over the internet. It handles requests from browsers and delivers content from the server to the user's screen. Apache is known for its power, flexibility, and widespread use, underpinning various websites across different platforms. It supports a range of features including secure communication, URL rewriting, and load balancing. Apache plays a crucial role in the development and deployment of dynamic web applications, making it a fundamental tool for web developers and hosting service providers.
HAProxy is a free and open-source software that functions as a load balancer and proxy server. It efficiently distributes incoming network traffic across multiple servers to ensure the reliability and performance of web services. HAProxy is widely used for high traffic websites as it improves the speed and availability of applications by spreading requests across multiple servers. It also provides features for monitoring, security, and fine-tuned control over traffic flow, making it a preferred choice in various network environments to ensure continuous web service operations.
Ignition files are used in the initial setup of Red Hat CoreOS systems, like those managed by OpenShift, to automate the configuration of new machines. When a Red Hat CoreOS instance starts for the first time, it reads an Ignition file to correctly set up system elements according to predefined specifications. This file can configure storage options, network settings, and user accounts among other things. Essentially, Ignition files streamline the deployment and scaling of systems, making it integral for efficient management of containerized applications with technologies like OpenShift on-prem or OpenShift Container Engine.
OpenShift, a container application platform by Red Hat, handles both authentication and authorization to manage user access. Authentication is checking if a user is who they claim to be. OpenShift can authenticate users through local credentials, or external sources like LDAP or GitHub. Once authenticated, authorization in OpenShift determines what actions a user can perform. It uses role-based access control (RBAC) to assign specific roles and permissions to users or groups, ensuring secure access control to its resources, crucial for both on-prem and cloud environments using OpenShift Container Engine.
A local image registry in the context of containerization, like with Red Hat's DO180 OpenShift course, acts as a private storage and management facility for Docker images on your local system. This registry allows you to securely store and manage container images necessary for application development, without the need to retrieve them from public registries. This setup is particularly beneficial in environments using OpenShift Container Engine or OpenShift on-prem solutions, promoting efficient, safe, and faster development cycles by facilitating immediate and reliable access to all required images within an organization's firewall.
Role-Based Access Control (RBAC) is a method used to restrict access to systems and data based on individual roles within an organization. Each role is assigned specific permissions, ensuring users only have access to the information necessary for their job. This system boosts security by minimizing unnecessary access and simplifying management tasks, as permissions do not need to be customized for each user, but are managed at the role level. RBAC is particularly effective in environments like corporate networks or cloud systems, where managing individual user permissions across vast systems would be impractical and insecure.
Cluster health checks are essential for maintaining the robustness and efficiency of a computing cluster, such as those managed with OpenShift Container Engine. These checks involve monitoring, diagnosing, and ensuring that all parts of the cluster function optimally. Regular health checks help in identifying and fixing issues like network failures or resource bottlenecks. This proactive approach minimizes downtime and guarantees smooth operation, which is crucial for systems deployed on-premises with OpenShift or managed through solutions like **DO180 OpenShift** and **Red Hat DO280**, ensuring they meet their operational objectives efficiently.
Deploying and managing applications involves setting up software on a platform so it can run smoothly, updating it regularly, and keeping it secure. Red Hat DO180, focused on OpenShift, teaches the basics of creating and managing these applications within the OpenShift Container Engine. This is ideal for running applications either on your own premises (OpenShift on Prem) or in the cloud. Conversely, Red Hat DO280 dives deeper, guiding you in the effective management and troubleshooting of OpenShift installations. OpenShift ensures your applications perform efficiently and scale easily, in a secure and supported environment.
