Kubernetes or OpenS hift Key Differences Explained | iCert Global

Kubernetes and OpenShift are two tools that assist you in running and managing containers on several computers that are collaborating. Both tools contain numerous attributes that simplify writing, managing, and deploying large applications.

Each option has pluses and minuses, but some variations make one more suited to you. OpenShift includes additional tools such as security, monitoring, and management. Consequently, it is possibly more difficult to install and utilize. Kubernetes is more popular, light, and simpler to start with because it is more adaptable.

OpenShift

OpenShift is a Red Hat platform based on Docker containers and Kubernetes to control them. It possesses numerous features such as native security, monitoring, auto-scaling, and simple updates. OpenShift provides multiple pricing plans, hence it is suitable for small projects as well as large-scale corporations.

Kubernetes

Kubernetes is an open-source product developed by Google to execute containers. It has many of the same features as OpenShift but potentially is harder to install and execute. In addition, fewer individuals execute Kubernetes than execute OpenShift, so there are fewer resources to which new users can turn.

7 Most Important Differences Between Kubernetes and OpenShift

When it comes to containers, two of the most popular tools are Kubernetes and OpenShift. Both have many useful features, but some differences will make one better for you.

Now let's examine the key areas where OpenShift and Kubernetes differ, including security, web interface, deployment, CI/CD, image registry, and updates.

1. Product and Project

Kubernetes is an open project that anyone can contribute to making. OpenShift is something that Red Hat makes, so there is one company that has a hold on it.

2. Security

Kubernetes also offers role-based access, network policy, and encrypted secrets to secure containers. OpenShift also offers extra security features such as integrated Single Sign-On (SSO) and user management across multiple clusters.

3. Web Interface

Kubernetes also provides a basic web interface to manage applications and logs. OpenShift's web interface is more robust, where you can make applications, track clusters, and manage users easily.

4. Deployment

Kubernetes provides several deployment options—self-hosted, managed, or hybrid. Flexibility leads to mistakes. OpenShift implements a "container-as-a-service" approach that makes app deployment easier.

5. CI/CD

Kubernetes has built-in CI/CD tools, but OpenShift has more integrated tools such as Jenkins and Tekton. It becomes simpler for teams to develop and deploy software faster.

6. Integrated Image Registry

Kubernetes has a simple method of holding container images. OpenShift has an image registry that you can directly access using its web console, which saves you from accessing old or insecure images.

7. Updates

Kubernetes typically gives updates about "rolling updates." This allows you to access new features rapidly, but you will need to update frequently. OpenShift less frequently updates using "fixed updates." This gives more stability, but it gives less rapid access to new features.

Kubernetes Features

1. Automatic Updates and Restorations

Kubernetes can automatically update or roll back your apps. You tell Kubernetes what you want your app to be like, and it maintains it that way. If something goes wrong with an update, Kubernetes will roll it back to the last working version. This maintains your app running smoothly.

2. Distributing Load and Finding Services

Kubernetes assists in finding and linking the services by assigning a unique IP address and port to each service. The services are also labeled to determine the right one. When an individual desires to connect, Kubernetes sends the request to the right service and may maintain the connection open if necessary.

3. Managing Storage

Kubernetes manages storage for your applications. It can automatically create, attach, and detach storage when your containers require it. It also assists in backing up and duplicating data to preserve it. This way, everything is managed storage-wise and in one location.

4. Secrets and Configurations Management

Kubernetes is letting you store vital data such as passwords, or secrets, and configurations securely. It encrypts and regulates who can see and modify them. It keeps a record of who looked at what to avoid errors or security violations.

5. Automatic Bin Packing

Kubernetes can automatically organize your containers in such a manner that your computer resources such as CPU and memory get utilized properly. This enhances the performance of your applications and prevents any resource wastage. Kubernetes also resolves issues automatically and can remove or add containers to handle more or less load.

OpenShift Features

1. Scalability

OpenShift is a recently launched platform that allows developers to quickly develop, deploy, and host apps in the cloud. Scalability is a key feature. This means that OpenShift can scale up quickly to support lots of users and lots of apps at the same time.

2. Flexibility.

OpenShift is a highly flexible platform when it comes to managing apps since it is microservices-based. Thus, every feature of an app can be managed and scaled separately without interfering with the other features.
