Industry Use Cases of RedHat OpenShift.

What is Red Hat OpenShift?

Red Hat OpenShift is a Kubernetes distribution focused on developer experience and application security that’s platform agnostic. OpenShift helps you develop and deploy applications to one or more hosts. These can be public facing web applications, or backend applications, including micro services or databases. Applications can be implemented in any programming language you choose. The only requirement is that the application can run within a container.

In terms of cloud service computing models, OpenShift implements the functionality of both a Platform as a Service (PaaS) and a Container as a Service (CaaS). Using OpenShift as a CaaS, we can bring a pre-existing container image built to the OpenShift Container Initiative (OCI) Image Specification (image-spec) and deploy it.

The PaaS capabilities of OpenShift build on top of the ability to deploy a container image, by providing a way for us to build in OpenShift our own container image direct from our application source code and have it deployed.

The application source code can include a Dockerfile with instructions to build a container image. Or, we can use a Source-to-Image (S2I) builder, which takes your application source code and converts it into a container image for us, without we needing to know how to write instructions for building a container image.

With its foundation in Kubernetes, OpenShift Container Platform incorporates the same technology that serves as the engine for massive telecommunications, streaming video, gaming, banking, and other applications. Its implementation in open Red Hat technologies lets us extend our containerized applications beyond a single cloud to on-premise and multi-cloud environments.

OpenShift is a container application platform integrated with Docker and Kubernetes. (If you do not understand Docker or Kubernetes, we recommend you to read first) Now let’s see. What can it do

Build a container (which Red Hat claims to be highly secure) from Red Hat Enterprise Linux.
Easy to deploy and scale the machine is also easy. We have got Kubernetes in it as well.
build auto, deploy auto, scaling, health check, etc. (This one may not be Wow much, CI / CD is that).

Data area is managed dynamics, storage level is disclosed.
There is a webconsole to deal with our containers (this one I tried and considered UX good).
There are Application Images, Database Images, Quickstart Application Templates, whether it is Django, Jenkins and others.

Self-service, on-demand application stacks

Develop your apps with the language and tools we want. Red Hat OpenShift includes pre-created quick start application templates that allow us to build and deploy our favorite application languages, frameworks, and databases with one click — Java, Node.js, .NET, Ruby, Python, PHP and more.

Red Hat OpenShift 4 offers even more advantages for developers, including:

Operator framework
OpenShift service mesh
CoreOS
Serverless

Docker container and runtime packaging

Built around a standardized container model powered by Red Hat application programming interfaces (APIs) for the Docker format, applications created on Red Hat OpenShift can easily run anywhere that supports Docker-formatted containers.

Code and Push

Develop container-based applications in the cloud or locally using the Red Hat CodeReady Containers, or OpenShift command line tools to create a fully-functioning OpenShift instance on your local machine. Then, deploy our work to any OpenShift cluster.

Deploying to OpenShift is as easy as clicking a button or entering a git push command. OpenShift is designed to reduce or eliminate many of the systems administration headaches related to building and deploying containerized applications. OpenShift also allows us to fully control the deployment lifecycle.

Streamline the delivery process

Standardizing workflows, supporting multiple environments, enabling continuous integration, and managing builds — OpenShift gives us tools for the complete development lifecycle.
