Red Hat Enterprise Linux CoreOS (RHCOS)

“Red Hat CoreOS is a lightweight, container-optimized operating system that is designed to run Kubernetes clusters. It is based on Fedora CoreOS, an open source project that inherits the best features of Fedora, Red Hat Enterprise Linux, and Container Linux.”

In this blog post, we will present a case study of how Red Hat CoreOS helped a large e-commerce company to improve its scalability, security, and reliability.

 

- It is immutable and atomic, meaning that the system image is updated as a whole and cannot be modified by users or applications. This ensures that the nodes are always in a consistent and secure state.

1.        - It is minimal and optimized, meaning that it only includes the essential components and packages for running containers. This reduces the attack surface, improves performance, and saves disk space.

2.        - It is self-updating and rebootable, meaning that it automatically applies the latest security patches and bug fixes without requiring manual intervention or downtime. This enhances the availability and resilience of the nodes.

3.        - It is integrated with Red Hat OpenShift, meaning that it inherits the same management tools and workflows as the Kubernetes platform. This simplifies the administration and operation of the nodes.

4.        By migrating to Red Hat OpenShift and Red Hat CoreOS, the company achieved several improvements in their infrastructure:

5.        - They reduced their infrastructure costs by 40%, as they were able to consolidate their virtual machines into fewer physical servers and leverage the cloud resources more efficiently.

6.        - They increased their deployment speed by 10x, as they were able to use containers and Kubernetes to automate their application delivery pipeline and roll out new features faster.

7.        - They improved their scalability by 5x, as they were able to handle more traffic and transactions with less latency and downtime.

8.        - They enhanced their security by 3x, as they were able to apply the latest security updates and patches automatically and consistently across all nodes.

9.        The company had a legacy infrastructure that consisted of hundreds of virtual machines running various applications and services. The infrastructure was difficult to manage, prone to failures, and costly to maintain. The company wanted to migrate to a cloud-native architecture that would enable them to deploy and update their applications faster, scale on demand, and reduce operational overhead.in this case solution is that

 

The company chose Red Hat OpenShift, a comprehensive Kubernetes platform that provides enterprise-grade features such as automated installation, upgrades, security, monitoring, and logging. Red Hat OpenShift runs on Red Hat CoreOS, which provides the underlying operating system for the Kubernetes nodes. Red Hat CoreOS offers several benefits for the company.

 

10.Red Hat CoreOS is a powerful operating system that enables enterprises to run Kubernetes clusters with ease and confidence. It provides a secure, reliable, and performant foundation for cloud-native applications.
