Red Hat multi-cluster management & what's new in OpenShiftKangaroot
More and more organisations are not only using container platforms but starting to run multiple clusters of containers. And with that comes new headaches of maintaining, securing, and updating those multiple clusters. In this session we'll look into how Red Hat has solved multi-cluster management, covering cluster lifecycle, app lifecycle, and governance/risk/compliance.
OpenShift 4 provides a fully automated installation and day-2 operations experience. It features over-the-air updates, hybrid and multi-cluster management through operators, and services for developers like OpenShift Service Mesh and Serverless. The operating system is Red Hat Enterprise Linux CoreOS, which is immutable and tightly integrated with OpenShift.
In this session, Diógenes gives an introduction of the basic concepts that make OpenShift, giving special attention to its relationship with Linux containers and Kubernetes.

1) Kubernetes is an open-source platform for automating deployment, scaling, and operations of containerized applications. It provides container-centric infrastructure and allows for quickly deploying and scaling applications.
2) The main components of Kubernetes include Pods (groups of containers), Services (abstract access to pods), ReplicationControllers (maintain pod replicas), and a master node running key components like etcd, API server, scheduler, and controller manager.
3) The document demonstrates getting started with Kubernetes by enabling the master on one node and a worker on another node, then deploying and exposing a sample nginx application across the cluster.
8 - OpenShift - A look at a container platform: what's in the boxKangaroot
Many already have some familiarity with containers, and maybe even with Kubernetes. But what's the difference between those and a container platform? In this session the goal is to look at OpenShift, Red Hat's container platform based on Kubernetes. We see what it's made out of, what makes it tick, and what the future of OpenShift & Kubernetes holds.
This document provides an overview of Red Hat's OpenShift Platform-as-a-Service (PaaS). OpenShift simplifies and automates the development, deployment and scaling of applications. It allows developers to focus on coding instead of managing infrastructure. OpenShift runs applications securely in isolated containers (gears) on top of Red Hat Enterprise Linux. Developers can use integrated tools or a web console to develop, build and deploy applications. OpenShift then automatically scales applications based on demand. The open source OpenShift Origin project allows organizations to run their own private PaaS or contribute to the community.
Red Hat OpenShift on Bare Metal and Containerized StorageGreg Hoelzer
OpenShift Hyper-Converged Infrastructure allows building a container application platform from bare metal using containerized Gluster storage without virtualization. The document discusses building a "Kontainer Garden" test environment using OpenShift on RHEL Atomic hosts with containerized GlusterFS storage. It describes configuring and testing the environment, including deploying PHP/MySQL and .NET applications using persistent storage. The observations are that RHEL Atomic is mature enough to evaluate for containers, and Docker/Kubernetes with containerized storage provide an alternative to virtualization for density and scale.

Kubernates vs Openshift: What is the difference and comparison between Opensh...jeetendra mandal
Kubernetes is an open-source container orchestration system that automates deployment, scaling, and management of containerized applications. OpenShift is a container application platform from Red Hat that is based on Kubernetes but provides additional features such as integrated CI/CD pipelines and a native networking solution. While Kubernetes provides more flexibility in deployment environments and is open source, OpenShift offers easier management, stronger security policies, and commercial support but is limited to Red Hat Linux distributions. Both are excellent for building and deploying containerized apps, with OpenShift providing more out-of-the-box functionality and Kubernetes offering more flexibility.

stackconf 2022: Data Management in Kubernetes – Backup, DR, HANETWAYS
Kubernetes is everywhere now, right? You see how companies are embracing this technology more and more, it’s like the Kardashians or Rosalía or TikTok; MAINSTREAM! BUT, as companies evolve and grow their container environments, they realize that stateful apps require more than a robust Kubernetes distribution, data is the key of their apps. Applications are as important as the data that they use. Managing 1M bank transactions is not the same as using bridge images, so you have to be very careful on how you control and use that data. Portworx is here to help with those problems. In this session, we will see how Portworx is able to manage volumes in the cloud with Kubernetes in seconds AND migrate that data from cluster to cluster in minutes, even a Disaster Recovery environment with ZERO data loss and NO downtime.

Deploying NGINX in Cloud Native KubernetesKangaroot
Using cloud-native application services is easy, it “just works”. Many customers choose them without giving it a second thought. However, these app services vary from cloud to cloud, with differing levels of quality and numbers of features making visibility and control inconsistent across clouds.
And then there is cost…it’s hard to know what your deployment is going to cost until after it’s been built. Often the services must be compiled in a piecemeal fashion and many products carry bloated code that increases costs.
Finally, security is often an afterthought. Moreover, SecOps teams struggle to keep up with the breakneck app release cadence that has become typical. Often they are seen as DevOps viewing them as a major constraint on the ability to deliver software quickly.
In this workshop, we showcase the NGINX solutions for cloud native Kubernetes that will allow you to:
- Reduce tool sprawl and provide a standard set of services
- Control costs with lightweight and easy solutions
- Bring teams together with automation and self‑service capabilities
Cloud demystified, what remains after the fog has lifted. Kangaroot
The document provides an introduction to cloud computing concepts from Infrastructure as a Service (IaaS) to Platform as a Service (PaaS) to Software as a Service (SaaS) to Database as a Service (DBaaS). It discusses different cloud models including private, public, multi-cloud and hybrid clouds. It also covers cloud native technologies like Kubernetes and microservices. The document cautions that while cloud promises flexibility and agility, the realities of cloud adoption require assessing one's specific business needs and whether a cloud provider can truly deliver the desired advantages. It promotes BigAnimal as a fully managed PostgreSQL database service in the cloud to help enterprises with their cloud journeys.
From NetOps to DevOps, modern app teams need a self‑service, API‑driven platform that integrates easily into CI/CD workflows to accelerate app deployment and makes app lifecycle management easier – whether your app has a hybrid or microservices architecture.
Built to manage NGINX Plus instances, NGINX Controller is cloud‑native, secure, and high‑performance. During this webinar, we demonstrate how NGINX Controller can streamline the management of your NGINX Application Services.
