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."
"They have provided a new interface, which is great."
"I think Ubuntu's main strength, as opposed to using the other Linuxes, has been its ability to encourage user feedback."
"Windows needs a refresh option to refresh its screen, but Ubuntu doesn't need that. It refreshes automatically and works well."
"The most valuable feature is the user interface."
"What makes Ubuntu easy to use is the large set of applications and the interface. The graphical interface is user friendly."
"Ubuntu is free and stable."
"Since Ubuntu is freely available for download and use, there is virtually no investment required, resulting in a high ROI."
"The auto upgrade operating system feature."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"It would be nice to see more compatibility with certain Microsoft solutions, such as OneDrive."
"The learning curve is quite high for non-technical users. Therefore, it's not a suitable solution for a general office environment."
"It could always be a bit more secure."
"If the user interface were further improved then it would be better because more people would be able to use it."
"When you talk of some of the flexibility, like you want to install from scratch, Windows is more user-friendly compared to Linux."
"I think Ubuntu is not that secure."
"Ubuntu could add some additional hardware support."
"The product must provide integrated security solutions."
