CoreOS vs Linux Kernel: What are the differences?
### Introduction
CoreOS and Linux Kernel are both operating systems, but they have some key differences that set them apart.
### 1. Scalability:
CoreOS is designed for large-scale deployments in the cloud, making it highly scalable and efficient in managing containers and services. On the other hand, the Linux Kernel is the core component of the Linux operating system, providing the necessary functionality for running applications on a single machine or server.
### 2. Containerization Focus:
CoreOS places a strong emphasis on containerization, with tools like rkt and Docker built into the OS for running and managing containers. In contrast, while Linux Kernel supports containerization through tools like Docker, it is not inherently focused on this aspect.
### 3. Automatic Updates:
CoreOS automates the process of updating the operating system and applications, ensuring that systems are always up to date with the latest security patches and features. Linux Kernel, on the other hand, relies on manual updates by system administrators, which can be more time-consuming and prone to human error.
### 4. Minimalist Design:
CoreOS follows a minimalist design philosophy, stripping away unnecessary components and focusing on security and reliability. In comparison, the Linux Kernel is a comprehensive operating system that includes a wide range of features and functionalities.
### 5. Immutable Infrastructure:
CoreOS promotes the concept of immutable infrastructure, where the operating system and applications are treated as disposable components that can be easily replaced. This approach enhances security and facilitates automated deployments. On the other hand, Linux Kernel does not inherently adopt this approach, relying more on traditional configuration management practices.
### 6. Enterprise-Friendly Features:
CoreOS offers enterprise-friendly features such as support for Kubernetes, distributed system capabilities, and robust security mechanisms. While the Linux Kernel can also be used in enterprise environments, it may require additional third-party tools and configurations to achieve similar levels of scalability and security.
### Summary
In Summary, CoreOS and Linux Kernel differ in terms of scalability, containerization focus, automatic updates, minimalist design, immutable infrastructure, and enterprise-friendly features.
Decisions about CoreOS and Linux Kernel

Netdata introduces Linux eBPF (Extended Berkeley Packet Filter) monitoring. With this enabled, monitor real-time metrics of Linux kernel functions and actions from the very same monitoring and troubleshooting dashboard used for watching entire systems, or even entire infrastructures.
This collector uses eBPF to monitor system calls inside your operating system’s kernel. For now, the main goal of this plugin is to monitor IO and process management on the host where it is running.

What is CoreOS?
It is designed for security, consistency, and reliability. Instead of installing packages via yum or apt, it uses Linux containers to manage your services at a higher level of abstraction. A single service's code and all dependencies are packaged within a container that can be run on one or many machines.
What is Linux Kernel?
Development on the LInux kernel.

What are some alternatives to CoreOS and Linux Kernel?
Docker
The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere
LinuxKit
LinuxKit, a toolkit for building custom minimal, immutable Linux distributions. Designed for building and running clustered applications, including but not limited to container orchestration such as Docker or Kubernetes.
Rancher
Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.
Docker Swarm
Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.
Ubuntu
Ubuntu is an ancient African word meaning ‘humanity to others’. It also means ‘I am what I am because of who we all are’. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers.
