Containers serve as a form of virtualization for operating systems. It accommodates everything from microservices to comprehensive applications in a single container. These containers contain essentials like executables, binaries, libraries, and configurations.
Unlike traditional server or machine virtualization, the container does not contain the entire OS image. Therefore, they are more portable, lightweight and resource-efficient.
Containers involve combining different applications to facilitate efficient construction, management and deployment across diverse infrastructures.
This approach empowers businesses with enhanced flexibility, scalability, and streamlined development of applications, resulting in acceptable benefits.
Comparing Kubernetes and OpenShift can be complicated, given that Kubernetes is an integral part of OpenShift. Created by Red Hat, OpenShift is often called the “enterprise version of Kubernetes.” Despite the fact that the selection of container orchestration options is limited, it is still difficult to choose the right option.
Compared to OpenShift, which integrates seamlessly with Kubernetes, Kubernetes automates the deployment, scaling, and operation of applications, while increasing application efficiency.
In this article, we will discuss in detail about two important platforms, Kubernetes and Openshift. We will also take a look at their key differences and features. Stay with us till the end to know in detail about these two most important platforms of DevOps.
What is Kubernetes?
- More than a decade ago, Google’s developers founded Kubernetes. It is an open-source technology that revolutionized Container-as-a-Service (CaaS). Kubernetes stands as a versatile, open-source solution for containerization, enabling developers to automate the entire lifecycle of containers, including deployment, management, scaling, and networking.
- This platform is a base for efficiently handling the wide-scale management of distributed applications housed within containers. With Kubernetes, developers determine the desired deployment location for their software, and the platform accomplishes most of the deployment and management tasks.
- Kubernetes provides many benefits to application developers, including self-monitoring, process automation, container load balancing, and storage planning. It is now located within the Cloud Native Computing Foundation.
- For streamlined management and exploration, Kubernetes organizes containers into logical clusters. Importantly, it operates seamlessly across diverse scenarios spanning cloud environments, on-premises systems, and even hybrid cloud configurations.
- The lasting impact of Kubernetes lies in its ability to empower developers with the tools they need to harness the full potential of container applications, regardless of the infrastructure they are deployed on.
Features of Kubernetes
- Now, let’s check out some of the features of Kubernetes in the following table.
- Kubernetes High Availability Kubernetes provides automatic failover and load-balancing features that guarantee the availability of applications even during hardware or software failures. Self-healing Kubernetes monitors the health of containers and applications and can automatically restart or replace failed containers, ensuring seamless application operation. Portability Kubernetes provides a uniform and transportable environment for deploying containerized apps across diverse infrastructure providers such as public cloud and data centers. Tanana Kubernetes has extensive extensibility, including a comprehensive set of APIs that enable custom controllers and operators to automate unique infrastructure tasks.
What is OpenShift?
- OpenShift is developed by Red Hat, a cloud development platform offered as a service (PaaS). This is beneficial for developing cloud-based applications.
- Under the PaaS model, Red Hat’s OpenShift emerges as a user-friendly open-source cloud platform, committed to the smooth development, testing, and preparation of applications prior to cloud deployment.
- This reliable platform makes it easy to use the integrated development environment (IDE) for the development and deployment of containers in Docker format. OpenShift accommodates diverse application frameworks such as Node.js, Ruby, Python, Perl, and Java.
- The platform’s automatic and manual scalability system meets the requirements of container applications, ensuring the best performance.
- OpenShift works as an abstraction layer that contains the key virtualization principles. Its essence revolves around virtualization, a concept that builds virtual systems rather than physical replicas.
- This basic concept is essential to OpenShift’s architecture. At the same time, its role in streamlining cloud-based development and facilitating the realization of flexible, scalable applications is critical.
Features of OpenShift
Some of the important features of OpenShift are given in the table here.
- OpenShift Features Description Developer Experience OpenShift prioritizes a user-friendly experience for developers, and provides streamlined tools and workflows that simplify the creation, testing, and deployment of applications. Security OpenShift ensures the security of containerized applications through various measures such as role-based access control (RBAC) image scanning and container isolation. Automation OpenShift simplifies containerized application management with automation functionalities such as automatic scaling, rolling updates, and self-healing capabilities.
The Difference Between Kubernetes and OpenShift
There are some key differences between the two advanced platforms Kubernetes and OpenShift, which we will discuss in the table below.
- The difference between Kubernetes and OpenShift Kubernetes OpenShift Definition Kubernetes is an open-source containerization platform that allows developers to manage services and their workloads. OpenShift is a cloud-based platform that allows developers to develop and deploy their applications on a cloud infrastructure. Deployments can be installed on various platforms and Linux distributions. Specific platforms such as RHELAH, Fedora, or CentOS are required. Platform It is an open-source framework called Container-as-a-Service (Caas). It was launched by Google. It is a cloud development platform known as Platform-as-a-Service (PaaS). security No built-in authentication / authorization. Strict security policies have a secure option by default. help Large active community, and extensive framework / language support. Small support community, mainly from Red Hat. Release and Update There are about four releases per year. About three releases per year, fewer concurrent updates. Networking Supports third-party network plug-ins. Provides Open WeSwitch with native plug-ins. Templates Provide more flexible helm templates. Less flexible and user-friendly templates. Image Registry No unified image registry supports a private registry. Integrated image registry that works with DockerHub / Red Hat. No complete out-of-the-box solution integrates with CI / CD devices. Provides certified Jenkins containers for CI. User experience Complex web interface, which requires additional setup for access. A user-friendly online console with a simple, one-touch login page.
