CoreOS vs Debian: What are the differences?

Developers describe CoreOS as "Linux for Massive Server Deployments". CoreOS is designed for security, consistency, and reliability. Instead of installing packages via yum or apt, CoreOS 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 CoreOS machines. On the other hand, Debian is detailed as "The Universal Operating System". 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.

CoreOS and Debian belong to "Operating Systems" category of the tech stack.

"Container management" is the primary reason why developers consider CoreOS over the competitors, whereas "Massively supported " was stated as the key factor in picking Debian.

According to the StackShare community, Debian has a broader approval, being mentioned in 387 company stacks & 390 developers stacks; compared to CoreOS, which is listed in 45 company stacks and 12 developer stacks.

    What are some alternatives to CoreOS and Debian?
    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.

    #ATComputing

    Since #ATComputing is a vendor independent Linux and open source specialist, we do not have a favorite Linux distribution. We mainly use Ubuntu , Centos Debian , Red Hat Enterprise Linux and Fedora during our daily work. These are also the distributions we see most often used in our customers environments.

    For our #ci/cd training, we use an open source pipeline that is build around Visual Studio Code , Jenkins , VirtualBox , GitHub , Docker Kubernetes and Google Compute Engine.

    For #ServerConfigurationAndAutomation, we have embraced and contributed to Ansible mainly because it is not only flexible and powerful, but also straightforward and easier to learn than some other (open source) solutions. On the other hand: we are not affraid of Puppet Labs and Chef either.

    Currently, our most popular #programming #Language course is Python . The reason Python is so popular has to do with it's versatility, but also with its low complexity. This helps sysadmins to write scripts or simple programs to make their job less repetitive and automating things more fun. Python is also widely used to communicate with (REST) API's and for data analysis.

    We use Debian and its derivative Ubuntu because the apt ecosystem and toolchain for Debian packages is far superior to the yum-based system used by Fedora and RHEL. This is large part due to a huge amount of investment into tools like debhelper/dh over the years by the Debian community. I haven't dealt with RPM in the last couple years, but every experience I've had with RPM is that the RPM tools are slower, have less useful options, and it's more work to package software for them (and one makes more compromises in doing so).

    I think everyone has seen the better experience using Ubuntu in the shift of prevalence from RHEL to Ubuntu in what most new companies are deploying on their servers, and I expect that trend to continue as long as Red Hat is using the RPM system (and I don't really see them as having a path to migrate).

    The experience with Ubuntu and Debian stable releases is pretty similar: A solid release every 2 years that's supported for a few years. (While Ubuntu in theory releases every 6 months, their non-LTS releases are effectively betas: They're often unstable, only have 9 months of support, etc. I wouldn't recommend them to anyone not actively participating in Ubuntu the development community). Ubuntu has better integration of non-free drivers, which may be important if you have hardware that requires them. But it's also the case that most bugs I experience when using Ubuntu are Ubuntu-specific issues, especially on servers (in part because Ubuntu has a bunch of "cloud management" stuff pre-installed that is definitely a regression if you're not using Canonical's cloud management products).

    At labinator.com, we use HTML5, CSS 3, Sass, Vanilla.JS and PHP when building our premium WordPress themes and plugins. When writing our codes, we use Sublime Text and Visual Studio Code depending on the project. We run Manjaro and Debian operating systems in our office. Manjaro is a great desktop operating system for all range of tasks while Debian is a solid choice for servers.

    WordPress became a very popular choice when it comes to content management systems and building websites. It is easy to learn and has a great community behind it. The high number of plugins as well that are available for WordPress allows any user to customize it depending on his/her needs.

    For development, HTML5 with Sass is our go-to choice when building our themes.

    Main Advantages Of Sass:

    • It's CSS syntax friendly
    • It offers variables
    • It uses a nested syntax
    • It includes mixins
    • Great community and online support.
    • Great documentation that is easy to read and follow.

    As for PHP, we always thrive to use PHP 7.3+. After the introduction of PHP 7, the WordPress development process became more stable and reliable than before. If you a developer considering PHP 7.3+ for your project, it would be good to note the following benefits.

    The Benefits Of Using PHP:

    • Open Source.
    • Highly Extendible.
    • Easy to learn and read.
    • Platform independent.
    • Compatible with APACHE.
    • Low development and maintenance cost.
    • Great community and support.
    • Detailed documentation that has everything you need!

    Why PHP 7.3+?

    • Flexible Heredoc & Nowdoc Syntaxes - Two key methods for defining strings within PHP. They also became easier to read and more reliable.
    • A good boost in performance speed which is extremely important when it comes to WordPress development.

    As the basis of our new infrastructure, we use CoreOS as a reliable solution for our docker-server-instances. We plan to deploy all our servers as individual docker containers to make use of the extensive possibilties offered in terms of isolation, resource-managemant (cgroups) and scalability.

    Debian is our primary distribution for our game-servers for the time being. We plan to shift our infrastructure towards Docker-Containers/CoreOS though.
