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."
"The solution has proven to be scalable. It can scale quite well."
"The product is easy to use."
"The main feature of the solution is it has a command-line editor."
"It is easy to use, performs great, and is stable and scalable."
"I feel the graphical interface to be very user friendly, as is first time installation."
"The setup cost is free."
"The most valuable feature of this solution is that Linux has cost-effective licenses."
"For us, OpenStack is awesome. We want something that will be much simpler than a broad and complicated solution."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"The solution could improve its GUI personalization."
"Management monitoring and interface could be better."
"The biggest improvement, which is also applicable to Linux in general, with Ubuntu Linux is getting things standardized as to where you're going to put your configuration files and how they're going to work. Package names also need to be improved so that the package name doesn't have any match with configuration file systems and things like that. Ubuntu is still better than some of the others, such as Red Hat Linux or CentOS."
"I would recommend they improve the network security, because it can be very difficult. I mentioned that when you upgrade Ubuntu, the network cut is always deactivated, so you have to restart the service to reactivate the network. It is important to improve this ability."
"The product could be easier to manage."
"Ubuntu could be improved with more container integration and orchestration of those containers. We are looking to have more cloud-based solutions, like Docker, and container-based solutions, or Kubernetes-based solutions integrated with Ubuntu. Instead of going for VMs, we would like to have more container-based solutions on top of Ubuntu."
"It could be easier for beginners and the user interface could be more user-friendly."
"The booting of Ubuntu Linux should be faster because I only have two minutes when I have calls, so it should complete more quickly."
 

Pricing and Cost Advice

"​Old equipment works for at least two or three years more, which means a significant savings.​"

"We are not using the licensed version of the solution, we are using the free version."
