CentOS Reviews

Our clients are pharmaceutical companies, and they're hesitant to change anything that's working. They want us to continue with what's proven. So we stayed on CentOS 7 for a long time. If we changed, we'd have to provide extensive validation that the new operating system is perfect and has no vulnerabilities.

However, CentOS 7 reached its end of life a few months ago, forcing us to migrate to CentOS 9. This was a big effort because we have a lot of in-house servers. For the production servers on AWS, we didn't face any issues migrating from CentOS 7.

The in-depth documentation available for CentOS is great. If I need to install a feature or fix a server issue, I can easily find answers online. The CentOS community is also vast and helpful. Overall, I think it's a very good Linux distribution.

We work on the terminal. If you work on the server, the command-line interface makes perfect sense because we need to do automation, and that requires entering commands. The command-line utility works perfectly. I have no issues with it.

For security, we have an AWS load balancer in front of our servers. We don't give public access to our CentOS servers directly. That's why I haven't focused much on CentOS's security features, as AWS is ultimately responsible for the security.

One issue I recently faced, but I think it was due to my IT support guys, was that when the server storage gets full, the service crashes. It's very difficult to regain access and stability in that situation. That could be improved.

So, the stability might be improved. But I don't think it's a CentOS-level issue. The system administrators need to come up with a solution for that, but I don't think it's CentOS's fault. I haven't done any research [R&D] on this issue.

There's one thing for sure. We recently migrated from CentOS 7 to CentOS 9, and it was a bit difficult. For example, updating Windows is simple; you just download it, and it takes about 15-20 minutes. But that's not the case with migrating from CentOS 7 to 9. 

We had to back up the entire server, launch a new server, and then restore the backup to the new server. We couldn't directly migrate. I think that was a bit of a problem. The setup and updates are not that new in CentOS.

Everyone in my company has used CentOS from the very beginning. So, we've been using it for the past five to six years. We used CentOS 7 for four or five years. 

It's very stable. We've hosted other solutions for about three to five years, and I've never seen an issue at the OS level. But upgrades are a different story.

It is a pretty scalable product. Currently, our production schools are hosted on CentOS. So, that is about ten lakhs (one million) users could be using it. I'm not entirely sure about the exact number, but since the application is hosted on the CentOS operating system, that's the approximate user base.

A ton of articles are available on the internet about CentOS, so I haven't really felt the need for active support. But overall, you can say that the internet is still a great source of information on how to work with CentOS.

The setup is pretty straightforward. We've installed other facilities that are just as good. There's nothing particularly different in the process.

The integration is as good as any other Linux platform. If another Linux platform can integrate with something, then CentOS can also integrate with it.

I think we don't pay for it. It's a Linux distribution, so it's open source. But I'm not sure if they might be charging for support or not because I haven't contacted their support.

For CentOS, I would rate it as nine out of ten.

CentOS is pretty old now, so I wouldn't recommend anyone use it. Everyone should follow the Docker container model at the moment. They should build their Alpine images of Dockers and host them. 

If they want to host them in the cloud, then AWS ECS (Elastic Container Service) works fine. If they want to host their services on-premises, they can use Kubernetes to host them.

We use the solution for file servers and emails. It is an operating system. Our email server, file server, and web server are running on CentOS.

The product is stable. We have to update it every once in a while. The vendor updates the tool regularly to solve vulnerabilities. We have to do patches. The software and hardware compatibility are updated. The vendor updates the versions to keep up with the new hardware.

The solution must improve its security. It must provide security against hackers. The security features must always be updated.

I have been using the solution for more than 15 years.

The tool is stable. I rate the stability a ten out of ten. It doesn’t shut down or crash.

The tool is not for large systems. We have about 20 users in our organization. We are not planning to change the solution for now.

We get plenty of support from the web. Since the product is open-sourced, a lot of community support is available. We can find answers to our queries.

The initial setup is easy. I rate the ease of setup an eight or nine out of ten. The time taken for deployment depends on what we have to add to the tool. Generally, the deployment can be done in about an hour.

The product is free. It’s open-sourced. It is the biggest advantage of the product.

Many software applications are open source. We do not have to spend money on them. Many people are using CentOS. It is a popular OS for those who don’t want to spend lots of money on Windows. People who are knowledgeable in setting up servers use the product. Those who do not know the technical setup choose Windows. CentOS users are programmers with technical knowledge.

Overall, I rate the solution a nine out of ten.

My company plans to drop the use of CentOS since Red Hat has stopped offering it support.

The tool was useful for hosting our company's website and email servers.

The value that my organization gained from the use of the product stems from the fact that we were able to use our email effectively, and we had only done a small deployment for the email servers.

The product lacks a graphical user interface that can help users automate certain systems using the native features offered by CentOS. The aforementioned area can be considered for improvement in the product.

I have experience with CentOS.

It is a very stable solution. Stability-wise, I rate the solution a nine out of ten.

My company used to host email servers with the help of CentOS. There were around 400 users of the product in our company.

My company has not used the technical support of the product since it was a tool that relied on the community-driven part to provide help to its users. My company could use search engines to get answers whenever we faced any issues with the product.

I have no experience with other tools in the market.

The product's initial setup phase was straightforward and not complex, especially if you are familiar with CLI. There can be an issue in the product's setup phase if you are a person who uses graphical interfaces.

The solution is deployed on an on-premises model.

CentOS is an open-source tool.

CentOS and other Linux products have almost the same features, but Fedora Linux, a product that is a more futuristic tool, was a bit buggy. The aforementioned area consists of details on why my company chose to work with CentOS.

There was nothing special that I liked about the product in terms of features that were positive for team management in our company. My company only needed a robust system that was also secure. Though my company knew about various Linux products, a major reason for opting for CentOS stemmed from the fact that it was closer to Red Hat Enterprise Linux.

I don't know about the stability and security features of the product since it was an area involving technical decisions that were taken care of by the technical domain in my company. Presently, there is no support available for the product, and I believe that the updates should also stop shortly.

We did not need any technical staff to take care of the product since everything was okay with it until our company took care of the updates and upgrades provided by the tool.

I feel that the product shouldn't be stopped, and CentOS should focus on improving the tool.

The management of updates in the product was straightforward, and it used to happen every week, after which it was usually promoted to production, but it was all manual work, and my company did not try to automate it.

I rate the overall product a nine out of ten.

We used the solution as an operating system. We were using CentOS because it supported the Red Hat flavor. Now that CentOS has stopped providing the support, we have switched to Alma OS.

We used the solution as an operating system. The solution is simple to use.

Currently, CentOS is not providing support, so you will not get new packages that are compatible with that operating system.

The solution provides good stability.

I rate the solution’s stability a nine out of ten.

Around 70% of our organization is using CentOS.

We previously used Ubuntu. We switched to CentOS because it was a business requirement, and our clients demanded it.

CentOS is an open source that is free of cost.

I would recommend CentOS to other users because it supports the Red Hat flavor. It is easy to integrate the solution with other tools and systems.

Overall, I rate the solution a nine out of ten.

In my company, we use CentOS to work in my test environments on my laptop. I didn't implement CentOS on the enterprise server.

My company uses it like a work server, and I got access to services provided by Apache and ManageEngine, which I used to deploy solutions, especially the minor ones like Elasticsearch. I didn't use other solutions because of security reasons in my company. I use it for testing purposes related to DNS servers, directory servers, binding servers, and Hyper-V servers, which are minor cases.

CentOS is not very different from other solutions apart from its distribution since it is a free edition of Red Hat.

I find the solution's stability to be the most valuable feature of it since I have been using a virtual machine with the help of the solution since 2015, and it still works on all the laptops in my organization.

I don't think any improvements are needed in the solution since we can just use it to test Red Hat before deploying it in our IT environment. We can learn more about CentOS from Red Hat.

In the future, CentOS should provide a free or open-source version for its community, which can involve improving and testing it.

CentOS NetworkManager is an area of concern in the solution that needs improvement, and it is the same with other products from Red Hat. CentOS NetworkManager was better earlier compared to what it is nowadays. The implementation or configuration would be better if there was some new CentOS NetworkManager available.

I have been using CentOS for seven to eight years. I currently use CentOS 7. I haven't got ISO on my laptop to use CentOS 8 in my test environment.

It is a highly stable solution.

It is a scalable solution. When testing the product, I found its scalability features very stable while considering its impact on the testing phase I was involved in with the tool.

CentOS has no technical Support since it is an open-source or free edition platform. If I face any issues or I want to learn something about the product, then I would have to learn them through the online communities for the tool. In Linux, you can find every documentation you need by doing a simple Google search or on the online communities created for CentOS.

The initial setup is the same as installing an ISO file in Red Hat. The product allows me to configure the IPS and allows me for automatic configuration, making a big difference. If a person is familiar with Linux, the setup phase gets easy. If a person is familiar with Windows, installation will be hard for the first time.

Considering the use of the solution for my company's test environment, the deployment process takes only a minute or two.

There are no cons in CentOS or Red Hat products. The cons are mostly found in Microsoft products.

It is completely easy to maintain the solution. I haven't faced any issues with CentOS. For CentOS, I have a virtual environment on my laptop in a VMware workstation. If I face any issues with CentOS, it will be because of VMware workstation owing to the version or edition I use.

CentOS is a good product for testing and learning purposes. You can go with CentOS or Linux if you are into cyber security.

With CentOS, I didn't conduct or operate myself in a GUI environment for testing or learning purposes.

I rate the overall product a ten out of ten.

It's normally next to our operating system, which helps us to install our servers, et cetera.

I'm satisfied with the product. It fulfills our desired needs.

We haven't had any issues with performance. The stability is good.

The initial setup is easy.

You can work with the UI or in command line, if you prefer.

It is scalable. 

It would be ideal if Red Hat would continue the CentOS versions in an open-source format. They seem to be moving away from that. Now only paid versions are available. 

I've been using the solution for six to seven years. I've used it since CentOS 5.

The solution is stable, and the performance is good. For years, we have had no complaints. There are no bugs or glitches and it doesn't crash or freeze. It is reliable.

The solution scales well. 

We have about 50 or more systems set up in our organization. I'm not sure how many users are on it. 

I'm not sure if we have plans to increase usage right now. 

I've never used technical support. If we need to troubleshoot, we look at blogs and forums. 

I have previously used Windows. 

The initial setup is straightforward. It's very easy to set up. We did not find it complex in any way. 

The UI makes it very easy. You just go through it step by step. Of course, if you like, you can also do command line as well. 

How long it takes to deploy depends on the speed of the system. It's got very good capacity and a nice configuration setup. It can usually be installed in 20 minutes to half an hour. If a person has experience with Linux, they can likely install a server in 15 minutes. 

We used it as an open-source solution. We did not have to worry about licensing. 

We are using the latest available version, which is on the cloud only.

My understanding is that CentOS is a Red Hat product now, so CentOS is now converted to CentOS Stream. It's not open-source anymore. 

I'd rate the solution nine out of ten.

CentOS is one of the standard platforms we use to perform jobs.

There was a team of 15 people who were using this solution.

In Microsoft Windows, we store the data in a graphical way, but in CentOS we can store the data based on the command. That is the specialty of CentOS.  In Windows, you can store the data in folders, and anyone can still see that data. In CentOS, it's more secure.

I like the command prompt of CentOS. It's very simple. You can share your files based on command prompt.

I would like the integration to be more secure.

I've been using this solution for one year.

It's stable.

It's very scalable. It's open-source.

We're also using Solaris. We're mostly using these for database storage to fix details and manage the organization data.

Installation is simple. It doesn't take much time. It's just a simple operating system.

The price is very good.

Once you buy the license, Linux will provide you with yearly or monthly patches, so your systems will be scalable for a long time. You can decide whether or not you want to install a patch. They're giving patches instead of going for automatic updates because some of the services will not work.

I would rate this solution 10 out of 10.

I would recommend this solution 100% for someone who is working in IT.

I have set up some databases on CentOS, like MySQL, MariaDB, Oracle, and RabbitMQ.

Regarding the most valuable features of the product, I can say that an operating system is a very robust tool. The product doesn't consume unnecessary resources, and it is very lightweight as an operating system. In our company, we are able to do a lot with the limited or small amount of resources offered by the tool. The aforementioned area covers my favorite aspects of using a Linux-based product like CentOS.

I have had a tough time with the product's scalability, making it an area where improvements are required.

I have been using CentOS for five to six years.

It is a robust and stable solution. Stability-wise, I rate the solution a ten out of ten.

Though it is scalable, the processes attached to it are not straightforward.

There are around four to five people who use the product.

The product's initial setup phase is very straightforward. For a technical person, it can be very easy to install the tool.

One needs to follow a standard deployment process for CentOS. It has a few simple steps, and as long as we use the correct parameters, it will spin up the OS correctly.

My company gets regular updates on the product, which helps to save our company's costs.

The product's security features are really good.

The integration capabilities of the product with other tools in the market are okay.

CentOS is a lightweight operating system that offers stability. I would recommend CentOS or any other Linux-based tools.

I have not used any AI with CentOS.

CentOS is an open-source product, so there are no licensing costs attached to the tool.

The value of using the solution is the fact that it is a lightweight product that is easy to implement.

I rate the solution an eight out of ten.

Many of my customers use Linux as their client operating system because it is more secure. Since it doesn't have a UI and there are a lot of anomalies and viruses affecting the UI-related applications, some customers prefer to have an operating system without a UI. I have seen most people use CentOS, Red Hat, or Ubuntu as a client operating system or server.

CentOS is very easy to use, and all the commands are user-friendly. Installing any package or application is pretty easy with CentOS. Security-wise, most of the latest security software and applications are compatible with CentOS. Updating the patches for CentOS is very easy.

CentOS is a stable, consistent, and secure solution.

The solution’s stability could be improved.

I have been using CentOS for three years.

CentOS is a very stable solution.

I rate the solution an eight out of ten for stability.

The solution is very scalable. CentOS is very good for any microservices or any application that has an auto scalability mechanism available. The number of users usually depends on how many users can access the OS through the network based on the bandwidth.

The solution provides good technical support for all flavors of Linux.

The solution’s initial setup is very straightforward.

The solution’s deployment takes hardly 10 to 15 minutes. You can use the image to manually deploy the solution, or you can use the DevOps or any automation methods to deploy it.

CentOS provides very good cost efficiency. It is a very efficient operating system without any hassle or inconsistencies. I don't see much difference between CentOS and Ubuntu. Ubuntu has a few more user-friendly commands than CentOS. Once you are familiar with the flavors, CentOS is also very user-friendly. For a new user of Linux, Ubuntu is a little bit easier.

Overall, I rate the solution an eight out of ten.

I primarily use the solution for personal and testing purposes. It's used as an operating system. 

The solution is easy to use. The performance is good.

The community and knowledge base are very robust.

It has a lot of great features. 

It is stable and reliable.

I have found the solution to be scalable. 

The support could be a bit better. They should be more customer friendly. They could also be a bit faster. 

I've used the solution for many years. I've used it for almost five years at this point. 

It's stable. I'd rate it nine out of ten for reliability. There are no bugs or glitches. It doesn't crash or freeze. The performance has been fine. 

The solution is scalable. I'd rate the scalability nine out of ten. 

I'm not sure how many people are using the solution in my company. 

Support could be faster and more responsive. However, support is okay. 

Positive

I'm also using Ubuntu. 

The initial setup is very straightforward. It is not complex. I deployed both on-premises and cloud options. It only takes a few hours. 

I followed the documentation for preparing the nodes and the administration. There's good documentation for configuring time zones, networks, et cetera. The steps are pretty standard. 

We had development and infrastructure teams on the solution. However, only one person can handle the deployment. I only have details on just my team and area. I'm not sure what it was like across the company. 

I handled the implementation in-house by myself. 

I've never looked into the ROI of the solution. 

I do not handle licensing. It's not in my scope of work.

I've used the latest version of the solution. 

I would recommend the solution to others. I'd advise people to have a clear view of how they will use the solution and take care to consider how they would like to scale. 

I'd rate the solution eight out of ten.
