CloudLinux vs Docker: What are the differences?

Introduction

In this article, we will discuss the key differences between CloudLinux and Docker. CloudLinux and Docker are both technologies used in the field of cloud computing, but they serve different purposes and have distinct features.

Architecture: CloudLinux is an operating system designed specifically for shared hosting environments. It provides isolation and resource allocation features to ensure stability and security for multiple websites hosted on a single server. On the other hand, Docker is a containerization platform that allows you to package and deploy applications with their dependencies, providing a lightweight and portable runtime environment.
Virtualization: CloudLinux uses a kernel-based virtualization approach known as Lightweight Virtual Environment (LVE). LVE allows for fine-grained control over resource allocation among multiple users on a shared server. In contrast, Docker uses containerization technology that operates at the operating system level. It leverages the host operating system's kernel and doesn't require a separate guest operating system, resulting in better performance and efficiency.
Isolation: CloudLinux provides isolation at the user level by limiting resource usage for each individual user. It ensures that one user's activities do not negatively impact the performance of other users on the same server. Docker, on the other hand, achieves isolation at the application level. Each container is self-contained, with its own file system, process space, and network stack, providing strong isolation between applications.
Deployment and Scalability: CloudLinux is primarily used for shared hosting environments where multiple websites are hosted on a single server. It enables easy management and scalability of hosting services with its resource allocation and isolation features. Docker, on the other hand, is designed for application packaging, deployment, and scalability. With Docker, you can easily package your application along with its dependencies and deploy it anywhere, making it well-suited for cloud-native and microservices architectures.
Resource Efficiency: CloudLinux provides resource allocation and management features to ensure fair share utilization of server resources among multiple users. It optimizes resource usage by limiting excessive resource consumption by any particular user. Docker, being a lightweight containerization platform, offers efficient resource utilization by eliminating the need for separate guest operating systems. It allows for efficient packing of applications and reduces the overhead associated with running multiple instances of the same operating system.
Flexibility and Portability: CloudLinux is specific to the shared hosting environment and is tightly integrated with the underlying operating system. It provides stability and compatibility for hosting providers and their customers. Docker, on the other hand, offers flexibility and portability by encapsulating application dependencies within containers. Docker containers can be easily deployed across different environments, making it easier to be consistent in development, testing, and production environments.

In summary, CloudLinux is an operating system designed for shared hosting environments, providing resource allocation and isolation features. Docker, on the other hand, is a containerization platform for packaging and deploying applications with their dependencies, ensuring portability and scalability across different environments.

Advice on Docker, CloudLinux

Decided

lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.

What are some alternatives to Docker, CloudLinux?

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.

Debian

Debian systems currently use the Linux kernel or the FreeBSD kernel. Linux is a piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. FreeBSD is an operating system including a kernel and other software.

Arch Linux

A lightweight and flexible Linux distribution that tries to Keep It Simple.

Fedora

Fedora is a Linux-based operating system that provides users with access to the latest free and open source software, in a stable, secure and easy to manage form. Fedora is the largest of many free software creations of the Fedora Project. Because of its predominance, the word "Fedora" is often used interchangeably to mean both the Fedora Project and the Fedora operating system.

Linux Mint

The purpose of Linux Mint is to produce a modern, elegant and comfortable operating system which is both powerful and easy to use.

LXD

LXD isn't a rewrite of LXC, in fact it's building on top of LXC to provide a new, better user experience. Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers. It's basically an alternative to LXC's tools and distribution template system with the added features that come from being controllable over the network.

CentOS

The CentOS Project is a community-driven free software effort focused on delivering a robust open source ecosystem. For users, we offer a consistent manageable platform that suits a wide variety of deployments. For open source communities, we offer a solid, predictable base to build upon, along with extensive resources to build, test, release, and maintain their code.

Linux

A clone of the operating system Unix, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance.

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.

Gentoo Linux

It is a free operating system based on either Linux or FreeBSD that can be automatically optimized and customized for just about any application or need.
