OverviewTechnologyOpenShift vs KubernetesBenefitsWhy Red Hat

Red Hat® OpenShift® is an enterprise grade open source application platform for accelerating thedevelopment and delivery of cloud-native applicationsin a consistent way across the hybrid and multi cloud, all the way to the edge. It is powered by Kubernetes as the container orchestration engine, and many more features from the CNCF open source ecosystem, all tested, packaged, and supported together as a comprehensive application platform by Red Hat. It can be consumed as either a public cloud service from the major cloud providers such asAWS,Microsoft Azure,Google, andIBM, or as aself-managed software on the broad spectrum of bare metal and virtual infrastructure across data center, public clouds, and edge.

Kubernetes by itself is anopen source software that automates deploying, managing, and scaling containers. Organizations need to manually integrate many other capabilities such as automation, monitoring, log analytics, service mesh, serverless, developer productivity tools, etc. to make it an enterprise ready platform.

Red Hat OpenShift and Kubernetes technology

Kubernetesclusters are the fundamental computing unit for both Red Hat OpenShift and Kubernetes. Each cluster has 2 parts: A control plane and worker nodes. Containers with software applications run in the worker nodes, each of which has its ownLinux operating system. The control plane is responsible for maintaining the cluster’s overall state (including what apps are running and which container images are used), while worker nodes run the actual production workloads.

The termDocker was once synonymous with containers, but now refers to several things:

  • A specific container technology
  • An open source community
  • A software company

The difference between OpenShift and Kubernetes

For all that Kubernetes can do to orchestrate containers, users still need to integrate other components like networking, ingress, load balancing, storage, monitoring, logging, multi cluster management, continuous integration and continuous delivery (CI/CD), and more to accelerate the development and delivery of containerized applications—at scale. Red Hat OpenShift offers these components with Kubernetes at their core because—by itself—Kubernetes is not enough.

The benefits of OpenShift vs Kubernetes

Kubernetes is a container orchestration software that helps users manage clustered groups of hosts runningLinux containers.

While Kubernetes is the core kernel, in order to build, deploy, run, and manage containerized applications at scale at 1 location, or in a consistent way across a distributed environment such as on-prem datacenters, public clouds, edge, you need more than just Kubernetes.

Red Hat OpenShift provides a complete solution that includes a stable Kubernetes engine with robust security and many integrated capabilities required to operationalize a complete application platform. It comes in several editions including as a fully managed public cloud service or self-managed on infrastructure across datacenters, public clouds, and edge.

Cloud services editions:
Self-managed editions:

Red Hat OpenShift focuses on an enterprise user experience. It’s designed to provide everything an organization may need to orchestrate containers—including enhanced security options andfull-time professional support—and to integrate directly into enterprises’ custom IT stacks, which may include:

What is DevOps?

DevOps is a set of practices that combines software development and IT operation to deliver software solutions.

What is serverless?

Serverless is a cloud-native development model that allows developers to build and run applications without having to manage servers.

Stateful vs stateless applications

The difference between stateful and stateless applications is that stateful applications save past and present information while stateless applications don’t.
