Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"Its security is the most valuable. It is very stable and has many features. It also has good performance. Some of our clients were using Windows servers and products. I suggested Red Hat Linux to them and described the features. They switched to it, and they really loved it. There were around 50 servers in my last company, and they switched all those servers from Windows to Red Hat. I used to manage those servers.""The integrated solution approach reduces our TCO tremendously because we are able to focus on innovation instead of operations.""The solution has features that simplify adoption for non-Linux users. There is an interface that you can activate on RHEL systems, and on other Linux systems as well, so that you will get a graphical user interface instead of just a shell. It's easier for an administrator who is used to only working on Windows.""It is a well-established operating system. We have tried to implement almost every feature of a version in our environment, and it has been very reliable. We are not facing many production issues on a day-to-day basis. They have well-documented articles on their documentation site and a knowledge base on their website. When we need to implement anything, we are able to find information about the best practices and the solution.""The feature that I like the most is that we can integrate it easily with our existing infrastructure. We found that it is much easier to deploy RHEL in our environment compared to a competing distribution like Ubuntu.""The best system I've ever used is Red Hat, in terms of its ability and consistency of the operating system. Other than that, the vast majority of applications that I had, you can deploy Red Hat with the support of the vast majority of applications. We don't have many issues with the OS, the support is very good.""We find the Red Hat Satellite deployments very useful. It integrates well with other solutions.""Customer support is valuable."

"The pricing is good. We pay a minimal fee.""The user access level is most valuable. When you do administration with CentOS, the number of customizations that you can do for each user is higher than other solutions. It is very customizable.""It has minimal updates compared to other distributions.""The product is free to use.""The most valuable feature is the limited resources the solution uses in operation.""I like its stability, performance, and usability.""The technical support is good.""It has all the features of Red Hat, but you don't have to pay for the subscription."

"It works well. It is very stable and very good. It is also very safe. It cannot be easily infected by viruses or attacks.""The stability of the solution is good.""Oracle Solaris was the preferred operating system for their customers to run their databases on and to get the best performance. It performs well with Oracle applications. Additionally, there are some features inside that are called zones which are Linux containers.""One of the main features of this solution is the ease of use.""Solaris is scalable because they have their own file system, like CFS.""Oracle Solaris is great due to the fact that it actually is meant for high-end servers.""The backup capabilities are quite good."

Cons
"Linux overall needs improvement. They cannot go much beyond what Linus Torvalds's kernel implementation can do. I come from AIX, and there were very cool things in AIX that I am missing dearly, e.g., being able to support not only adding, but also reducing memory and number of processors. That is not supported on Linux right now, and it is the same for the mainstream file systems supported by Red Hat. There is no way of reducing a file system or logical volume. Whereas, in AIX, it was a shoo-in. These are the little things where we can say, "Ah, we are missing AIX for that."""Their pricing and documentation can be improved.""It could be a bit more user-friendly. It could also be cheaper.""The price is something that can be improved, as they are still being undercut.""I'd like to see more of NCurses type menu systems in some instances. We're dealing with SUSE Enterprise Linux, they have an NCurses menu system. It's a menu system. It will write there. Even some of the higher-end Unix systems like AIX have some inner menu system where all the configuration tools are right there so your administrator doesn't have to jump through multiple directories to configure files if needed. I like the simplicity of Red Hat because it's pretty easy but having an NCurses menu when you have to get something done quickly would be nice.""Sometimes they don't have new versions for applications like Apache or PHP. I understand it's because they have to have support for them, so they can't have the latest version all the time, but that's the main thing I see that could be improved.""The biggest thing that is crushing RHEL is documentation. Their documentation is haphazard at best. The man pages that you can use locally are pretty good, they've been fleshed out pretty well, but the documentation from Red Hat itself really needs somebody to go through it and review it.""It is mostly better than other solutions. However, it is sometimes difficult for disaster recovery, so we have to plan accordingly."

"Like every operating system, it could be more secure.""The solution could improve by making the management tools better for the DevOps teams. For example, WebEX and Webstacks.""The YUM install manager can be improved. It is below average as compared to the other install managers. This is the only major problem that I see with CentOS. They should reduce dependency on the YUM manager.""I was using CentOS because it was very stable, and now it's not.""In the future, CentOS will no longer be compatible with Red Hat.""The server system is a little bit tough to manage.""Lacks sufficient security and some coding tools.""We occasionally have issues with software installation."

"Solaris is not easy to use. It needs better GUI, UI, and configuration tools.""It would be helpful if the solution offered backend management. In the 11.4 version, Oracle added a management console. It would be great if we maybe had a user management tool to go with it.""It is not easy to use. It doesn't have a user-friendly interface. It should be easy to use. We are planning to move from Solaris to Linux because Linux is more flexible and user-friendly. Its installation should also be easier. Solaris also needs specific hardware to work well, which is another reason why we are moving to Linux. It should be more flexible in terms of hardware. It should have better integration with other hardware platforms.""I believe before Oracle was using Oracle Linux, they were using Oracle Solaris for their customers who are using Oracle databases. This was because it was more optimized for the hardware built for it. It has good performance for the database only. However, if you take it out of the Oracle applications, it will not do well compared to other operating systems, such as Linux or even Windows can have better performance.""When we switch over to Solaris it was not easy because we had some troubles with the performance. Solaris is from Oracle and you would expect that it would run flawlessly, but we had some issues in sizing the previous Linux environment to the Solaris environment.""Currently, there are two variants, there's SPARC and there's x86. I would have wanted a scenario where they're all just one product."

Pricing and Cost Advice
"Red Hat Linux is inexpensive. Linux solutions are generally inexpensive.""Because it is a subscription, you can go elastic. This means you can buy a year, then you can skip a year. It is not like when you buy something. You don't buy it. You are paying for the support on something, and if you don't pay for the support on something, there is no shame because there are no upfront costs. It changes the equation. However, we have such growth right now on the Linux platform that we are reusing and scavenging these licenses. From a business standpoint, not having to buy, but just having to pay for maintenance, changes a lot of the calculations.""We have a site license on a yearly basis. Generally, we're okay with its price, but everything could be cheaper.""The licensing with Red Hat is on par with other organizations like Microsoft. We have a site license, which gives us a certain number of servers, perhaps 25,000, for the type of license that we have. That works really well for us.""In terms of the solution’s single subscription and install repository for all types of systems, we can have as many RHEL installations as we want because we have a specific subscription that entitles us to have as many RHEL services as we want. We pay for a subscription and with that we get RHEL and Satellite as well.""RHEL is expensive.""It is more expensive than other vendors in terms of pricing and licensing, but because of its stability, I have to go with it.""We are an educational institution and as such, what we pay is less than the average company."

"I'm not required to pay a licensing fee.""I use the free version.""CentOS is a free solution.""There is no price or licensing required — it's open-source.""There are no licensing costs for CentOS.""We have a CentOS license that we pay for on a yearly basis.""The solution is not subscription-based, unlike Red Hat.""We are using a subscription-based license option for CentOS."

More CentOS Pricing and Cost Advice »

"Its licensing is on a yearly basis.""The price is not good and needs to improve.""There should be an option to install the solution for free and just pay for the support. We purchased an annual license and the price could be better.""If you buy Oracle hardware it's supported free with the hardware. If you're putting it on non-Oracle hardware, that is when you buy the support license, which is also very reasonable. It is $1000 dollars per year, so it's not overly expensive.""This solution needs a license to use it."
