Overall Satisfaction with Red Hat Enterprise Linux (RHEL)

Red Hat Enterprise Linux (RHEL) is being used in our organization on a huge basis. From the deployment of servers to application management, all is done on RHEL. Thanks to its amazing and unbeatable features which help us in efficiently and effectively managing the assets. Because these servers are usually managed by the backend teams and the team which is running the show, the OS is majorly used by backend teams and not by everyone.

For the business problems, when an application performs well and with its maximum output, all the tasks are done in a well-oiled manner which in turn helps everyone to achieve great heights. Because of RHEL's fast and rock-solid performance, everything works perfectly and stays on the top of its game.
  • RHEL is Secure: Because everything on this OS depends on permissions, no Virus or malicious code can penetrate from one file to another. In RHEL everything works and can work with permissions. If some task is not having particular permissions to be performed, it can never be performed until and until the file is having appropriate permissions for it. Henceforth, even if any thing successfully penetrates in your system, it can never spread to other systems in network because everything locks the file out as it is not having appropriate permissions to be executed which make the system safe and secure.
  • RHEL is Fast: Most of the processes in RHEL remain on sleep and activates only when required unlike other OS. At one point in time, only 2-3 processes are active which are being used and rest all the systems remains sleeping and activates only when system or the user calls them. This eventually help the system to dedicate its 100% of processing power to the active processes which in turn increases efficiency of the system making is fast.
  • RHEL is Open Source: You can find the full code for this OS online and make any tweaks to the code as per your or your organizations needs. You are never forced to use the features that come out of the box and you always have the option to make any changes making this OS a very flexible one. The only catch in this advantage is that you can never sell the modified version of the OS but you can always use it for your and the organizational use.
  • RHEL's GUI: The Graphical User Interface (GUI) of this OS is particular old fashioned or you can say it depicts legacy view. This might be good for the old users but many users nowadays prefer new and animated graphics with advanced movements graphics. RHEL lacks a bit in this field as the GUI has hardly been modified since a very long time.
  • RHEL's Open Source Technical Support: RHEL does not provide free technical support if you are struck anywhere. You will have to buy the OS and technical support so as to avail the same. This is a tricky part since doing a lot of stuff in Linux requires in-depth technical knowledge which everyone is not aware of. So you can always search the questions online but many times you'll end up on Red Hat's official page which has the question but unfortunately you cannot view because you are not a subscribed user. Some sort of free support shall also be provided with the OS.
  • Overall, RHEL has helped us achieve heights in performance management and handling a large crowd at once with its huge management capacities. It is highly reliable and if used with apt load balancers you will not require more than one backup server because the crash frequency is minimal.
  • No negative impacted has been faced as of now since using RHEL.
Windows Server's are perfect competition for RHEL as many people use Windows Servers for deploying their applications. Windows provides good GUI but it lacks in many aspects in which RHEL is a win-win. As earlier mentioned, the performance of RHEL is unbeatable cannot be compared with the performance of any OS. Also, Windows is not that secure which also compromises the security of you applications which a major concern in today's world.

RHEL is well suited for deploying servers and applications. If you're happy working on a terminal and do not want much of graphical user interface, then RHEL is your cup of tea. It is highly reliable and makes you super happy performance-wise. You can easily set it up running and start deploying your servers and application on this OS and not worrying much about security since the OS itself is very secure.

If you're not fond of working on a black screen and need some sort of animations and cool icons to move around, then I would suggest RHEL is not your cup of tea since it lacks a lot in those aspects. However, the unbeatable performance of the OS is a major advantage which everyone shall consider while using computers.
