Executive SummaryUpdated on Mar 15, 2026

CentOS and Debian compete in the Linux distributions category, with CentOS having an upper hand in enterprise environments due to its historical stability and Red Hat compatibility.

Features: CentOS is favored for its stability, reliability, and long-term support, making it ideal for enterprise environments and server applications. It benefits from compatibility with Red Hat, providing peace of mind for updates and compatibility with vendor-supported hardware. Debian is praised for its flexibility, wide range of compatible software, and strong community support. Its lightweight architecture and stability make it a preferred choice for hosting websites and applications.

Room for Improvement: CentOS faces challenges with recent changes in its release process, affecting its stability and long-term support. Users express the need for more intuitive integration tools and better NVMe support. Debian could improve containerization features and hardware support, with a desire for streamlined user interfaces and more deterministic package management.

Ease of Deployment and Customer Service: Both CentOS and Debian have strong support from their respective communities but lack official technical support due to their open-source nature. CentOS is often deployed on-premises and in hybrid cloud environments, catering to business applications that demand stability and control. Debian is highly favored in public cloud environments, reflecting its adaptability and ease of integration with various infrastructures.

Pricing and ROI: CentOS is recognized for its cost-effectiveness as an open-source solution with no licensing fees, offering substantial savings on operating system costs. Debian, also free and open-source, emphasizes low costs associated with licensing and setup. Both distributions report high returns on investment, attributed to their stability, performance, and community support, though CentOS is often favored in enterprise settings due to its historical alignment with Red Hat.

Mohammad Wasif

IT Infrastructure Engineer at Trigyn Technology

Has supported reliable deployments and simplified issue resolution in complex environments

The most suitable feature of CentOS is its exceptional stability, security, and long-term support, which make it a popular choice for enterprise and server environments. CentOS is widely recognized for providing a stable and secure platform, especially suited for server and mission-critical workloads. Whenever we face critical work, it is easy for our team to handle. For long-term support, each CentOS release generally guarantees long-term updates, ensuring reliability for extended periods. For package management, we use YUM and DNF in the new version for flexible and efficient software management. It depends on our users' requirements for installing CentOS. Licensing for CentOS is above my management details, so I am not aware of this information. CentOS always provides good feedback, is easy to handle, and easy to troubleshoot. The experience with CentOS OS has been very good over the last two months. I rate CentOS nine out of ten.

Lightweight platform has reduced cloud costs and has kept long‑running web apps reliable

In my opinion, the best features Debian offers include its stability. The stable branch really is stable because once it is configured, I understand you can run it for a very long period of time without needing to reboot or update any of the components. That is really good when you want an application to be extremely stable and not go down, and you are happy using slightly older components. I also value the fact that Debian is open source, so it is free. That is very useful, and it has a big development community that builds it. I understand there are tens of thousands of software libraries which work with Debian from the apt package manager, APT, and also it is very lightweight, which I find to be good as well because that helps with cost savings. Debian's lightweight design benefits my organization because it does not come with bloatware, minimizing RAM usage. Because of that, we can choose cheaper EC2 instances. You do not have to have as powerful RAM, which makes things cheaper, and also because it does not come with all this bloatware, it also makes it faster. So it is very efficient. Debian positively impacts my organization by allowing us to utilize a much more lightweight operating system with Amazon EC2 instances, which greatly reduces costs because we can use EC2 instances with lower RAM. Cost savings are good. Debian is very well known across the industry, so different engineers from different teams know how to use it. Using the APT package manager is a common skill for cloud professionals, which makes it good, especially if you are hiring individuals into the company, because at least you would expect they have some type of background using Debian. I do not know exact measurements, but I would expect we could save at least 10% of costs with EC2 instances just because our memory and CPU requirements would be lower because Debian is lightweight. So it would save cost to some degree.
