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, and the version I am using is stable and allows us to make needed changes."
"Flatcar's support is good. The version I am using is stable and allows us to make needed changes."
"We have developed an internal Document Management System around Ubuntu and MySQL, which came at no extra cost and our efficiency has improved dramatically."
"This is a solution that I can recommend to other users who are interested in using it."
"I like this product much better than some other similar solutions."
"The most valuable features are stability and updates. We are not using the interface, the interface of the OS, we are using it as the server. We actually sync it through SSH and we deploy our application, so we don't have access to do it. The updates are very helpful and the way they update their OS is very helpful."
"It has improved our ability to carry out maintenance without downtime as migrating services between server environments is largely seamless."
"Ubuntu is very easy to use and you can manage it on your own."
"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 most valuable features of Ubuntu Linux is the reliability, the ease of package management, and the ease of upgrading from one version to the next."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"The development teams could sharpen their skills. They should offer applications on the net."
"Could be better support for graphic drivers and support from the hardware lenders."
"Ubuntu Linux could improve by having more out-of-the-box functionality for common plug-and-play devices, such as printers."
"The solution could improve by being more user-friendly, you need to know how to use the command-line interface which you might not understand."
"Windows we can handle by ourselves when it comes to troubleshooting, however, Ubuntu is a bit difficult."
"The solution could be more user-friendly, as I use Mac on a day to day basis."
"It could be easier for beginners and the user interface could be more user-friendly."
"There is a large open-sourced community that is helpful. I had a lot of problems when starting out and there was plenty of assistance throughout the community. Since everyone is helping for free the support could be better."
"Right now, I would recommend the solution at a six out of ten."
