CentOS 9 (centos 9) | Support by SupportedImages

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.

My main use case for CentOS  is technical support, fixing the network or service-related technical issues faced by the customers.

One of our products, a web server based on Nginx, uses CentOS  as the base OS. When a customer calls me stating they're not able to access the web UI of a certain product or not able to access the web server, I use the terminal to see the status of the services using different Linux commands. I can also try to restart the web services from CentOS commands; that's how I usually use it.

Sometimes I use CentOS to create cron jobs when I want a server to perform certain tasks at specific times. Instead of doing it manually, I can create automatic cron jobs so a service will be executed on a certain date or time.

In my experience, the best feature that CentOS offers is the network configuration of a device from the command-line interface, which is exceptionally clean.

Since joining my organization, which has been using CentOS, I've observed that all products with CentOS as a base OS run smoothly.

Even when a product does not function optimally, the base OS CentOS works smoothly; we can see the status of the services with the command-line interface, making it very efficient.

I think CentOS should introduce more security patches to fix different vulnerabilities.

I have been using CentOS for 10 years.

In my experience, CentOS is very stable.

CentOS's scalability for my organization has handled growth and changing needs smoothly.

The customer support for CentOS is amazing.

I would rate the customer support for CentOS a 10 on a scale of 1 to 10.

Positive

I am not aware of any different solution that was previously used before CentOS, as I was not part of the organization before, so I cannot comment on that.

I have seen a return on investment in terms of time. It saved a lot of time through troubleshooting, which gives us substantial room for improvement in terms of fixing things, so time saved is a good return on investment.

My experience with CentOS in terms of pricing, setup cost, and licensing is that it is an open-source operating system, so there was no cost in terms of deploying it or getting the license for it.

CentOS was the clear choice before choosing it; no other options were evaluated.

My advice to others looking into using CentOS is to go for it; it's the best OS. I rate CentOS 9 out of 10.

Positive

We primarily use the solution for testing software and applications in the IT industry. I also study the storage system of AI on CentOS .

CentOS adapts well to many software and applications, providing good compatibility. Additionally, there are many online communities to learn from, which is beneficial.

CentOS can be somewhat difficult for beginners, as it has a complex UI, especially for those not in the IT field. Adding more support could be beneficial, though Red Hat with IBM support is an alternative that may be costly. Also, modernizing CentOS could be a suggestion.

CentOS is a stable operating system, and I would rate its stability as nine out of ten.

I do not have personal experience with customer service for CentOS.

Positive

The initial setup was very easy. I would rate the ease of setup at 8.5 out of ten.

I am not responsible for the setup cost in my company, so I am unsure about the cost of the license.

I recommend CentOS for its stability and its ability to adapt to many software and applications. It is also very accessible.
