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

I have no experience with other tools in the market.

I have previously used Windows. 

I'm also using Ubuntu. 

Before joining the current company, I was using Ubuntu Linux. When I used CentOS the first time, I didn't find any hurdle or issue in using that OS.

For the production environment, we use Red Hat Linux and for the testing or relevant environment, we use CentOS.

Right now, with a Kubernetes solution and maybe we need a new solution as we are trying to move onto SecureNet. If we use, for example, EKS and right now, maybe in the future, we don't need to deal with an operating system. In the future, if we cause CentOS, we might use it in a smaller, more basic implementation.

We did not use anything previously. 

I did use Red Hat a long time ago, and I switched because they couldn't seem to decide how they wanted to charge for their service. I was perfectly happy to just pay them, but it would range by huge amounts. I couldn't maintain that.

We were also using SUSE Linux in Windows.

We were using Redhat Linux. We just had the application need, which is why we adopted this product.

We also use Red Hat.

Since they have changed their licensing strategy, we are using more Ubuntu. 

I've also used Oracle Linux as well. We put deep packet processing on the Linux solution.

I use MacOS, Windows, and Ubuntu on a daily basis.

For a server environment, I would recommend CentOS, but for normal usage, I would recommend MacOS.

When you buy a Mac it just comes with MacOS which is beautiful to work on. If I'm using a Windows laptop, I would go for CentOS. However, the problem with CentOS is there is no Microsoft Office.

At the time, there were quite a lot of options like Linux, Red Hat, and Ubuntu. But if you're already using these commands that work here, they will be the ones that work there. So, we chose CentOS.

Before CentOS, we used Red Hat Enterprise Linux. The reason why we approached CentOS is that it has the same flavor, but there is no subscription. Earlier, we were paying for Red Hat Linux on a yearly subscription. In order to minimize the cost, especially for some of the applications, it didn't make sense to pay on a yearly basis. 

We did not previously use another operating system. 

I've also used Debian and Ubuntu.

We've used Ubuntu in the past for various systems and projects, and once in a while, a vendor uses it for their platform. We don't care for the more aggressive updates, and we usually don't need the most updated packages.

We were using Suse Enterprise. It was too non-standard. We often ended up fighting its mysterious "Yet Another Setup Tool" to get things installed.

I am also familiar with Xilin.

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.

We used to use Windows 7, but we had issues with licensing and other things. 

I have used Kali Linux before. I switched to CentOS as it is free of cost and has a good infrastructure.

We previously used Oracle Linux. 

No. We started and created our solution around CentOS.Not at all complex. Anybody with basic Linux knowledge can install the server and almost anybody can easily install the desktop and get themselves familiar with it over a week

We are also using Ubuntu Linux.

For as long as I have been with the company, they have been using CentOS.

We uses Windows before.

Yes, BladeSystem. We changed the solution because the initial expenditure for BladeSystem is very high.

I have been working with the CentOS product since the beginning of my career.

We did not use a solution before this one.

No.

Approximately two years ago, I worked with Google Drive.

I also work with Kali Linux.
