CentOS Stream 10 Latest (CentOS 10) with support by ProComputers

My main use case for CentOS  is development and production servers. For development and production services, I use CentOS  to deploy, and I am currently using it to deploy Docker  Swarm applications for Dockerized applications for some legacy applications before we move them to Kubernetes .

In addition to my main use case, I have a few bastion servers I use for VPN connections.

The best features CentOS offers include stability, which I think is the most important. I have found CentOS servers to run very long without any issues, as well as clean updates that do not cause any downtimes.

CentOS's stability and clean updates have helped me in my day-to-day work and with my projects by providing predictable workloads and ensuring that I can assure stability for my stakeholders, which is the business. On features, security is always a good thing, and the important factor about CentOS is that security is a core feature. It is also part of the reason why the updates are so stable, which gives me the confidence to provide reports for the stakeholders.

Compatibility is great as Linux servers in general are usually amazing for deploying both development and production workloads, and performance has never been an issue because Linux is very good on resources.

I cannot think of anything that CentOS could be improved on at the moment. Considering the fact that I have not had any issues with needed improvements such as documentation, community support, or compatibility with newer technologies in the past number of years I have been running these servers, there is nothing to report.

I have been using CentOS for the past ten years.

CentOS is very stable.

Considering I use CentOS in legacy servers, I do not have a lot of experience scaling it.

I have not had any need to contact customer support for CentOS.

I have previously used Ubuntu  servers before, and the reason for my switch to CentOS was originally because of the security-forwardness of Red Hat based servers, as well as that hybrid kind of benefit you get from CentOS by receiving the updates from Fedora quickly in terms of the server environment. I found Ubuntu  sometimes can be relatively unstable, which is why I moved to CentOS.

I have seen a return on investment, particularly in terms of money saved because I do not pay for the servers. I only pay for the use of the servers; I do not pay for the operating system. I would not say it translates to fewer employees, but for time, it is greatly considered once again the stability. Time is always positively impacted by stable systems, so I would say there is a lot of time that has been saved.

My experience with pricing, setup cost, and licensing for CentOS has been very straightforward, as I use the free version of CentOS, so there is no fee for that.

Before choosing CentOS, I did evaluate other options, with Red Hat being one of them, but at the time, it was paid, so that is why I ended up using CentOS.

My advice for others looking into using CentOS would be to make sure you set up your update schedule to be manual so that you can choose when and how to do your updates. If you want a stable environment, choose a good cloud provider and set it up in your own way. I have also used it for bare metal, so there is not much I can provide in terms of that. I want to say keep up the good work with CentOS. I gave this review a rating of nine out of ten.

CentOS  is deployed in my organization on-premises. I have been working for my current company for the last two years and three months. We have a total of 64 servers in our infrastructure, and out of those, we use 10 to 12 CentOS  OS servers. The versions we use are 7 and 8. From my past experience, the server has never rebooted or had any critical situation.

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.

CentOS should provide updates more regularly. Kernel parameters, sysctl config details, tuned profiles, process prioritization, optimized disk, and input scheduler choice are all points for performance optimization.

Regarding needed improvements, expanding hardware resources, adding more RAM, and switching to SSD  storage would ensure hardware is able to match application demand.

I have been using CentOS for above six years.

From my past experience, the server has never rebooted or had any critical situation.

CentOS always provides good feedback. When I install CentOS, it is easy to handle and troubleshoot.

CentOS is stable, reliable, flexible, and very useful.

The experience from the last two months has been very good with CentOS OS.

CentOS's scalability is very supportive for both small deployments and large enterprise environments, making it very flexible. It allows users to scale resources vertically for upgrading hardware and horizontally by adding more servers, making it suitable for modern web hosting and containerized applications.

When we encounter issues or need troubleshooting assistance, we almost always find answers from the community or from other people's experience shared over the internet.

On our previous servers, we used RHEL  8 OS. After formatting that server, we installed CentOS OS on request of users. Using it for the last two or three months on the same servers, the server has not automatically rebooted.

When users request to install or create new servers, they specify their preferred OS. They declared for us to install CentOS OS, so we create the servers and install CentOS OS based on their requests.

Recently we have installed MariaDB  as a database, and for the OS, we use CentOS. Our physical server, which had RHEL  8 already installed, was not providing good performance. Our user requested to format the physical server and reinstall CentOS OS. I have recently installed CentOS OS version 8 on my physical server.

We provide infrastructure support to our customer, which is an Indian government PSU company, specifically the Ministry of External Affairs. They provided us with their data center. We developed the data center from scratch and created the entire infrastructure. We develop applications and websites, handling all infrastructure support from beginning to high level for our client.

My advice to others considering CentOS is that it offers significant advantages over other operating systems, making it an excellent choice for users seeking reliability and security. Key advantages include stability, reliability, and being free and open-source. It provides 100% free usage, along with security and long-term support.

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.

CentOS  is basically the community edition of Red Hat, and to get the flavor of Red Hat, users can visit centos.org to download the CentOS  distribution and install it in their virtual machine, VirtualBox, or any Hyper-V  platform. It gives users the Linux operating system based upon the Fedora flavor, providing an overview of how the enterprise version of RHEL  looks similar to CentOS, though the features are very different.

I have been using it for many years now for my own testing and working with the operating system and Linux features. It's mainly for testing and checking Linux features. For application development and server management features, we have been using CentOS for many years. It offers a wide variety of testing cases and checking Linux features as server management. Linux distribution such as CentOS has many features related to server management, checking storage and networking facilities, and integrating with use cases. One of the key specific projects I worked on was testing server administration-related work such as file protocol testing using SMB and NFS, and checking features for networking and other use cases.

CentOS is an open-source platform that is free to use, which is one of its unique features. It's an operating system that offers a foundational view of Linux systems and has been a go-to operating system for a long time. Even though I've used other versions such as RHEL , SLES, and others including Rocky Linux , AlmaLinux , and Oracle Linux , CentOS remains a top priority for my daily use cases.

The package management, security, and stability are the main aspects that stand out. Linux's built-in framework provides different layers of security on the file, permissions, and system levels. CentOS offers flexibility in package management features and excellent stability. The installation process is straightforward, even for someone with a basic foundation in Linux, making it user-friendly.

CentOS offers a secure environment with security mechanisms such as SE Linux and firewall protections. You can have a secure setup by having the necessary permissions for users and maintaining system-level access. Users who are not root have minimal command execution abilities, whereas root and sudo users have extended privileges.

Organizations using CentOS save on subscription costs and can run their applications effectively without upgrading to other versions such as RHEL. CentOS helps organizations and startups in cost optimization and application development.

The documentation and support could be improved, along with compatibility with newer hardware as hardware continually evolves over time. Additionally, if CentOS could receive better marketing and promotion, it might gain more traction among vendors, software developers, educational institutions, and colleges.

There is always room for improvement in any product, irrespective of challenges or how good the product is. In the current scenario with cutting-edge technology, improving the product to benefit a larger community would be a positive step.

I have been using CentOS for more than eight years.

Complex setups are not necessary. CentOS's simplicity and stability make it easy to use. It's scalable and user-friendly.

CentOS is scalable and user-friendly without requiring complex configurations.

The documentation and community support are great. I've seen many people across the globe interacting, and when users encounter issues, the community provides solutions. I faced an issue long ago, and it was resolved through the open-source community forum.

I have only used RHEL besides CentOS. RHEL is the enterprise-level flavor of CentOS itself. It's almost identical to CentOS.

The installation of CentOS is simple, offering both minimal and GUI installation options. A typical layman with a basic Linux foundation can easily navigate through the installation process.

The enterprise subscription cost is at a certain level, but CentOS saves customers from paying additional money, optimizing costs for enterprises and startups involved in application development.

Many are unaware of this operating system due to its open-source nature, but adequate marketing could allow many vendors, software people, institutions, and colleges to leverage CentOS. CentOS is a straightforward, non-complex operating system that offers great use cases.

Documentation and community support are crucial, and CentOS has active community engagement to assist users facing issues.

There is always room for improvement irrespective of how good the product is. Embracing new technology is essential.

I rate CentOS a nine out of ten.

There are a lot of applications posted on CentOS  machines, so I'm using this for supporting those applications.

The middleware applications such as Tomcat , Java, Apache HTTPd are examples of applications I'm supporting with CentOS . These applications are hosted on CentOS machines, and all of them are highly critical. We should take care, fix vulnerabilities that are reported, and implement necessary configuration changes, all of which are supported by my team.

Mainly, I'm supporting middleware applications with CentOS. Apart from that, I have many other use cases such as jobs running on the server that we need to maintain. If any space issues arise, we must clear them so the jobs will run properly. We manage the users logging into the servers and everything else.

These are the major things I'm supporting using CentOS.

CentOS offers an open community, so whatever issues arise, the solution is available in the open community, making it easy to search on Google and find fixes for the issues we are facing.

I find the performance and scalability very valuable in CentOS. CentOS excels in these aspects. Regarding security, as mentioned earlier, from the open community, whenever a new patch releases, we receive notifications and can review user experiences and potential issues before applying patches. Everything is easily accessible there, and when it comes to scalability and stability, CentOS provides a very good experience.

CentOS has positively impacted my organization since it is open source, reducing costs significantly. The performance given by CentOS is excellent, and no issues are being reported for applications, so everything is managed within this operating system. In terms of performance, it functions extremely well if we have enough RAM and storage space. We have not faced any CPU utilization alerts, and there have been no downtime reports from CentOS. That has been a great advantage for us.

I have been using CentOS in my current organization for the past six years.

Regarding specific metrics, when it comes to cost saving, it saves significant amounts. We have saved approximately 50% of our revenue by using CentOS. When it comes to downtime, previously we experienced downtime at least monthly, and now it has been significantly reduced.

My main use case for CentOS  is that we use it on some of our devices for VoIP or unified communications.

A lot of our older virtual appliances run CentOS , which includes our conference bridges and telephony switches.

The best feature CentOS offers is that it's free.

Stability is an important feature among others.

CentOS has impacted our organization positively by giving us an operating system for many of our virtual appliances, but for detailed information, you would need to consult someone in a higher position.

I think CentOS can be improved, but it's not really a viable option anymore. It could be brought back, but that seems unnecessary now that Rocky Linux  exists.

I have been working in my current career field for almost 12 years.

In my experience, CentOS is stable.

I haven't seen any issues with CentOS's scalability as I haven't had to scale it.

I did not previously use a different solution.

CentOS was the standard for our appliances, though I did not have any input in that decision.

Everything we did with CentOS was internal for the company, at Mitel.

My advice for others looking into using CentOS is to use Rocky Linux  instead.

I do not wish to add anything else about the features, including security, performance, or ease of management.

I haven't noticed any specific outcomes such as reduced costs, easier maintenance, better reliability in our team's day-to-day work, or less downtime.

On a scale of 1-10, I rate CentOS an 8.
