Salim Ahmed - PeerSpot reviewer
Has supported secure application hosting and reliable server management
I find the GUI to be good in Ubuntu Linux, and I appreciate the open SSH. The fact that it is free since it is open and open-source is why I appreciate it and feel it is secured. We have multiple different kinds of support related to Ubuntu Linux, including official support and other options. I am currently using laptops, desktops, and servers, and Ubuntu Linux supports all these devices. If I need it for Raspberry Pi or something similar, I can download another Linux distribution. Ubuntu Linux is scalable, especially for servers. We prefer using Ubuntu Linux Servers rather than Windows. The biggest advantage of Ubuntu Linux for me is that it is open-source, secured, and scalable.

Quotes from Members

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

Pros

"Flatcar's support is good. The version I am using is stable and allows us to make needed changes."
"Ubuntu Linux is flexible because it has a lot of new features, so you can use it without any problems."
"It is easy to use, performs great, and is stable and scalable."
"As we have repositories in my country, the ease of use and the open source nature of the solution are valuable features."
"The solution is free to use."
"RTO with the use of templating support for VMware for fast deployment of recovery or new systems, with the least amount work needed on custom settings, within application installed from install repositories. Shorter overall time with the vetted packages. Normally install and go."
"The solution is more secure than competitors such as Microsoft Windows."
"Windows needs a refresh option to refresh its screen, but Ubuntu doesn't need that. It refreshes automatically and works well."
"The biggest advantage of Ubuntu Linux for me is that it is open-source, secured, and scalable."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"If the user interface were further improved then it would be better because more people would be able to use it."
"The vendor must provide an official support team."
"It would be nice to see more compatibility with certain Microsoft solutions, such as OneDrive."
"On the desktop edition, we'd like more themes."
"Ubuntu Linux needs to improve its stability. I would like it to show the battery percentage at the screen top."
"One of the reasons people don't use Ubuntu on servers is because they are not as secure as Red Hat."
"I am really very satisfied with this solution. However, one thing that I would like to see improve, is to have better support for multiple screens with multiple resolutions. For me, that is the most important feature."
"There is not a lot of support for applications in Ubuntu Linux. In the industry, most of the applications work for Windows and Mac. There should be better integration with applications in the future."
