Linux's advanced terminal empowers versatile usage and ongoing secure development
Initially, there was nothing complicated. It's easy since I have many years of experience with it. However, if I were a beginner with Linux, it could be completely disruptive compared to Windows. So, I would have to spend some time practicing with Linux to understand how it works and how I can accomplish the same tasks compared to Windows. Maybe one month, at least.

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 is always adding more features."
"The setup cost is free."
"This open source operating system promotes very secure environments with less possibility of being attacked. Support for this system is great because of its quick SLA."
"The integration with other solutions like Apache is valuable."
"It is easy to use, performs great, and is stable and scalable."
"Overall, I rate this solution ten out of ten."
"There are many features I like about this solution, but one that stands out, is that it allows me to easily install new packages and to have recent packages available."
"The most valuable feature of this solution is that Linux has cost-effective licenses."
 

Cons

"The development teams could sharpen their skills. They should offer applications on the net."
"In terms of what could be improved, I would say management and storage. Mostly, the storage mechanism."
"The support can be improved."
"One thing I've noticed is network connectivity issues where packets are sometimes lost."
"When installing software, an online interface has to be used and commands written to run the installation. The solution could be improved if it was possible to click twice in an icon for the installation process to begin."
"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."
"I think Ubuntu's performance is fine and so is its user interface. However, the latter is not as fancy as Microsoft Windows. It could be a bit fancier and easier to use."
"The solution could improve by having the user interface use fewer resources."
"The solution could improve its GUI personalization."
