OPENSHIFT ADMINISTRATION Training

We offer private customized training for groups of 3 or more attendees.

Course Description

 

This hands-on course with lab exercises will help learners to install and manage an OpenShift cluster. Throughout the course learners will understand the benefits and purposes of the platform. This includes how to install the cluster, explore networking concepts, understand commands, manage OpenShift resources, configure storage, manage application deployments, and administer the cluster through logging and monitoring.

Course Length: 3 Days
Course Tuition: $2090 (US)

Prerequisites

Learners will need a working knowledge of Linux systems administration skills or the equivalent knowledge of skills found in the GL120 - Linux Fundamentals and GL250 - Enterprise Linux Systems Administration courses. Also learners will benefit from an understanding of containerization as found in the Docker course.

Linux Unix Uses & Stats

Linux Unix is Used For:
Desktop Mainframe Computers Mobile Devices Embedded Devices

Pros
Performance:
Linux supports many efficient tools and operates them seamlessly. Because it's architecture is lightweight it runs faster than both Windows 8.1 and 10. 
 
Security:
Because Linux is an open-source software,  anyone can contribute code to help enhance the users’ experience i.e., adding features, fixing bugs, reducing security risks, and more.
 
 
Software Development:
The terminal in Linux is a *wild card*. You can do almost anything with it. This includes software installation, application and server configurations, file system management, and etc.
 
Large-scale:
Open-source projects benefit from having an attentive community. As a result, Linux is more secure than Windows. Instead of installing anti viruses to clean malware, you just have to stick to the recommended repositories. 
 
Efficient: 
Developers have the convenience of running servers, training machine learning models, accessing remote machines, and compiling and running scripts from the same terminal window. 
 
Free: 
Linux is free (you can put it on as many systems as you like) and you can change it to suit your needs.
Cons
Learning Curve: 
Linux is not for everyone, there is a learning curve in switching to Ubuntu. To actually learn Linux efficiently would take a user one to several years.
 
No Tech Support:
Unlike Windows, there isn’t a dedicated tech support, so getting help for things is up to you. 
 
Designer Compatabilty:
Linux is not as user friendly as Windows or as ‘straight out of the box design’ As an example for design choices, Adobe hasn’t released any of its products to Linux users. So it’s impossible to run them directly. The Ubuntu alternative is a free software called GIMP. 
 
Gaming Capabilities: 
Most games aren’t available in Linux. But that’s not to say you can’t make it happen, it's just not as easy.
