Kubernetes Vs OpenShift Software:

When it comes to a container orchestration software, there are the two main options: OpenShift and Kubernetes. While both have their own benefits and drawbacks, comparing the two Kubernetes Vs OpenShift side-by-side in order help to make a decision about which one is right for the project.

    Points of DifferenceKubernetesOpenShift
    Programming Language Used Go Angular of JS and Go.
    Developed by A Cloud-Native Computing Foundation A Red Hat.
    Networking. It does not include native networking solution and only offers an interface that can be used by a network plugins are made by third parties. IT includes the native networking solution called Open Switch, which provides a three various plugins.
    Key Cloud Platform Availability. It is available on EKS for the Amazon AWS, AKS for a Microsoft Azure, and GKE for the Google GCP. Has a product known as a OpenShift Online, OpenShift Dedicated, as well as an OpenShift on Azure.
    CI/CD. Possible with the Jenkins but is not integrated within it. Seamless integration with a Jenkins is available.
    Updates. Supports many concurrent updates are simultaneously. Does not support a concurrent updates
    Security and authentication. Does not have well-defined security protocol. Has a secure policies and stricter security models
Openshift vs Kubernetes

Core Differences Between the Kubernetes and OpenShift:

When it comes to a container management, two of the most famous platforms In the market are the Kubernetes and OpenShift. Though both have a lot to offer in terms of a features and capabilities, there is still a lot of variance between the Kubernetes and OpenShift that could make one or other a better fit for a specific needs.The key areas where a Kubernetes and OpenShift differ, including the security, web-UI, deployment approach, CI/CD, integrated an image registry, and updates.

  • Product vs Project.
  • Security.
  • Web-UI.
  • Deployment Approach .
  • CI/CD .
  • Integrated Image Registry.
  • Updates .

Kubernetes vs OpenShift Software: Features:

1. Automated Rollouts & Rollbacks: Kubernetes has automated rollouts & rollbacks, making it simple to deploy and manage applications in the dynamic environment. With Kubernetes, and can declaratively specify a desired state of application, and Kubernetes will ensure that an application is always in that state.

2. Load Balancing & Service Discovery :Kubernetes services can be used for a service discovery & load balancing purposes. Every service is assigned a unique IP address and port number, which is used by a clients to access services. The services are also assigned labels, which can be used to identify a type of service.

3. Storage Orchestration :One of the key features of a Kubernetes is storage orchestration. This refers to a management of storage resources in Kubernetes cluster, and includes tasks like provisioning, attaching, and detaching volumes, creating and deleting persistent volumes, and more.

4. Secret & Configuration Management :Kubernetes provides the mechanism for managing secrets and configurations. Secrets can be stored in a JSON or YAML format and encrypted using a variety of methods, like AES-256-CBC.Configuration files can be stored in a JSON, YAML, or INI format.

5. Automatic Bin Packing :Kubernetes provides a number of powerful tools to help manage the containerized applications. One of most useful is its automatic bin packing feature.

6. Batch Execution :Kubernetes is the powerful container orchestration system that offers a number of features to help manage the containers. One of those features is batch execution, which enables to run containers in a batches.

7. Dual Stack IPv4/IPv6 :Kubernetes comes with the native support for both IPv4 and IPv6. Dual-stack supp also allows for a greater flexibility in networking and reduces the need for the network address translation (NAT).

8. Horizontal Scaling :One of major features of Kubernetes is a horizontal scaling. This means that system can scale up or down based on a demand, making it more flexible.

OpenShift Features

OpenShift Features:

  • Scalability.
  • Flexibility .
  • Open Source Standards.
  • Container Portability.
  • Automatic Installation & Upgrades.
  • Automation .
  • Edge Architecture Support.

Conclusion:

Kubernetes and OpenShift both are great choices for an orchestrating containers, but they have various strengths. If trying to decide which one to use in an organization, it’s important to understand differences between them. In general, a Kubernetes is bare-bones while OpenShift has more features.
