CentOS Review

Lightweight, powerful, and stable

How has it helped my organization?

We just see it as an operating system to run our applications. We're in the media industry and we make a lot of TV programs and OTT items. We have developed backend applications that make, let's say, 10 locations happen or make OTT happen.

Everything is running on CentOS due to the fact that it's lightweight. It's not a huge overhead. It's not like Windows eating up a lot of CPU resources. 

What is most valuable?

The performance in the past, the open-source approach, has been great. 

It helps us with our internal applications for very low pricing.

All our applications internally have been running on CentOS since 2006 when I joined the company so we have been developing on things like that.

We use the solution due to the fact that it's a lightweight, powerful, stable OS. It's being used for a lot of different use cases. 

The stability is very good.

The pricing is good. We pay a minimal fee.

What needs improvement?

Often, the solution doesn't scale as you expect.

I cannot recall if there are features that need improvement or if there's anything that should be added.

For me, it just has to perform and carry our application. I don't really care about how the user interface looks like as we don't use the user interface. We have an application running on it and that needs to be stable and that's the only thing. Therefore, we have no issues with the solution and don't feel it's missing anything.

The solution is stable, however, it could always be even more stable if possible.

CentOS recently announced some changes. I'm not sure what they will be, however, we look forward to seeing what they come out with. 

For how long have I used the solution?

I've been using the solution for about ten to 12 years or so. It's been a very long time.

What do I think about the stability of the solution?

The solution is very stable. The reason that we have standardized the usage of CentOS is the stability. It has proven to us to be very stable compared to other options. 

What do I think about the scalability of the solution?

I'm running around 1,400 CentOS VMs at the moment.

In terms of scalability, of course, things don't scale always as you want, however, it's a powerful solution.

The Dutch organization where I work has eight people on the payroll, however, we are not the users. We are the people building the backend and we have hundreds of thousands of people using the applications running on the data center. The people that watch OTT or watch television make use of parts of the installation.

How are customer service and technical support?

I'm not on the operational side of the business and therefore have never been in touch with technical support. I cannot speak to how helpful or responsive they are.

Which solution did I use previously and why did I switch?

We are using Ubuntu, CentOS, and also Red Hat. It really depends on the applications. If we buy applications or we use applications from vendors, if they say it has to run on Red Hat we'll run Red Hat. If they say it better runs on CentOS, it will run on CentOS. We have all the different file systems as we run applications that we buy or rent from vendors that make the applications.

How was the initial setup?

The initial setup is fairly straightforward. We have been using it for a long time it's an automatic deployment and has templates. People just have to click on the template being installed in the background. It's an automated process in VMware.

The end-user can go to the portal and they can just select which type of machine they want to have and which CentOS release is being deployed. It's a matter of minutes until they can log in.

What about the implementation team?

A company really doesn't need outside assistance. It's fairly automated and simple to manage. 

What's my experience with pricing, setup cost, and licensing?

The pricing is very reasonable. From what I understand, we pay a minimal fee, if we pay anything at all.

What other advice do I have?

We use different versions of the solution. It's a mixture depending on the application. Some applications are not upgraded by vendors and therefore we are using old versions. We try to stay with our own applications on the latest and greatest, however, generally, it's a mixture.

I'd rate the solution at a nine out of ten.

I'd recommend the solution to other organizations.
