Hi guys ! Today we are going to brief look at One of the most famous tool which is used very often across all over IT industry nowadays. Yes you guess is right ???? Yes it's OpenShift.
So let's have a look what is OpenShift and why do we industry uses OpenShift ?
What is OpenShift ?
- OpenShift is DevOps tools which helps?you to develop, deploy, and manage container-based applications. It provides you with a self-service platform to create, modify, and deploy applications on demand, thus enabling faster development and relea
- OpenShift can manage applications written in different languages, such as Ruby, Node.js, Java, Perl and Python. One of the key features of OpenShift is extensible, which helps the users support the application written in other languages.
- OpenShift helps organizations move their traditional application infrastructure and platform from physical, virtual mediums to the cloud.
- OpenShift supports a huge variety of applications, quickly developed and deployed on the OpenShift cloud platform. OpenShift supports three kinds of platforms for developers and users.
OpenShift Architecture
OpenShift is a layered system wherein each layer is tightly bound with the other layer using?Kubernetes?and?Docker?cluster. The architecture of OpenShift is designed to support and manage Docker containers, which are hosted on top of all the layers using kubernets.
OpenShift Developer experience
OpenShift provides following benefits to developer for testing, building their application without having the so much technical knowledge about CI/CD etc.
- Self service infrastructure
- Consistent environments
- Automated build & deploy
- CI/CD pipelines
- Configuration management
- App logs & metrics
OpenShift vs Kubernetes ?
According to the company, Kubernetes is the kernel of distributed systems,?while OpenShift is the distribution. At its core, OpenShift is a cloud-based Kubernetes container platform that's considered both containerization software and a platform-as-a-service (PaaS).
Some analogies
- Kubernetes is the engine (framework, project) that drives OpenShift.
- OpenShift is the complete car (product) that gets you where you want to.
Linux kernel vs Linux distribution
- Kubernetes is the ‘kernel’ of distributed systems.
- OpenShift is the distribution that focuses on the experience of both developers and administrators.
- Kubernetes plus many other upstream projects => project OKD, upstream of OpenShift
- OKD plus some other projects and RH support => product OpenShift
Major OpenShift 5 benefits
Trusted OS foundation: RHEL CoreOS or RHEL
- OpenShift 4 control panel can only be deployed on Red Hat CoreOS (RHCOS) – immutable, lower footprint, optimized for running containers and managing Kubernetes clusters at scale.
- Workers can be deployed on RHCOS or RHEL.
- RHEL CoreOS and RHEL make the perfect foundation for OpenShift to run anywhere from bare-metal to private and public clouds with the same experience.
- Automated installation and day-2 Operations which makes it easier to administrate, upgrade, and provide an enterprise container platform.
- Ubiquitous usage of operators to make all possible.
- Built-in Operator Lifecyle Manager (OLM) and rich ecosystem of operators.
- ′ Centralized logs: EFK (ELK) stack .
- Metrics and Monitoring: Prometheus, Grafana.
- Built-in OAuth provider .
- Strict security model, integral RBAC .
- Support microservices and serverless architectures .
- OpenShift Service Mesh provides Istio, Kiali, and Jaeger out-of-the-box to support microservices adoption .
- OpenShift Server less includes Knative and Keda (for Azure functions) .
- Allow to migrate legacy VMs to OpenShift by using Container Native Virtualization (tech preview) .
- Built-in Operator Hub which offers a catalog of over 180 services delivered through Operators .
- Developer perspective of web console dedicated to developers .
- Allow easy application deployment from different sources (git source, binary, external registry, Dockerfile, …) .
- Application topology view .
- CodeReady Containers: OpenShift 4 running on laptop .
- Out-of-the-box CI/CD features: Jenkins, Tektone .
