This diagram represents the reference architecture for a full high availability and disaster recovery solution. This solution can be individually tailored to address a single availability solution. For example, if only disaster recovery is needed the configuration supports exclusion of the HA replica.

The pace of innovation has shortened expectations for time to market, placing pressure on IT teams to keep up with the rate of change. Organizations need just-in-time, prescriptive resources to enable their teams to leverage innovation to solve business problems. The Red Hat Learning Subscription (RHLS) delivers unlimited, on-demand, modular access to Red Hat’s entire training portfolio including cloud based labs for a full year. The Early Access feature of RHLS enables subscribers to learn from real-time publishing of courses and labs currently in development.

I have been asked, tasked, and dropped in by parachute on an extraordinary number of occasions recently to answer questions about, and implement solution for, Single Sign On (SSO) to OpenShift Container Platform. These conversations can start in multiple ways:
- How do I do SSO to OpenShift?
- How do I integrate OpenShift with my existing SAML identity provider?
- How do I log into OpenShift with my PIV and PIN?
The goal of all of these questions is typically the same and all have the same answer. Organizations typically have an existing SAML based identity provider they use for single sign on, and in the case of many, especially government, organizations the identity is provided by the user via a PIV and PIN.

Automation within enterprise IT is not a new topic. Whether it’s automating the creation of a user desktop or a server, the drive has always been to automate as much as possible to achieve faster time to market and efficiency. What has changed, though, is the number of infrastructure elements one can automate within an IT org. I still remember my first job in college 15 years ago where I used a variety of tools to automatically deploy and configure Windows XP simultaneously across 50 desktop machines for a classroom lab environment. Today not only can we automate desktop computer deployments but also servers, applications, and even networking.

Digital transformation is not only changing the way businesses operate, but how they approach learning as well. Digital change has made continuous learning more important, putting pressure on employers to stay focused on employee learning or risk falling behind. But at the same time, digital transformation has made learning much more accessible. There is more training available online, on-demand than ever before. In today’s digital world, much can be learned without ever stepping foot into a traditional classroom.

Most of us have been using PAM when authenticating without really thinking about it, but for the few of us that have actually tried to make sense of it, PAM is the partner that always says “no”, unless otherwise stated. It’s the bane of any sysadmin’s existence when it comes to making system x secure, and it becomes a major pain point on and off when I forget about the normal rules of engagement.

Hello, my name is Christopher Tate and I want to show you how to set up virtualization and a virtual machine for DNS and Identity Management to open our OpenShift web console and routes to the network.
In my previous videos, I showed you how to install OpenShift with valid SSL certificates.
Hey Tate: Step by step securing OpenShift and routes with SSL certificates for development.
