I use Ubuntu Linux just for testing, e.g. as a workstation. I also use it for running some applications.
Ubuntu Linux is user-friendly. Patching and patch management for the system is also good.
The system is already user-friendly, but what could be improved is its ease of deployment. Its ease of use could also be improved.
I've been using Ubuntu Linux for more than five years.
From a stability perspective, Ubuntu Linux is quite stable. This is the reason I'm using it at home, e.g. for the lab. When I deploy it, it's quite stable, and I don't need to do anything else.
The initial setup for Ubuntu Linux was straightforward.
I implemented the system myself, and it took me less than an hour to deploy it.
The Ubuntu Linux version that I use is free. I just download it, install it on a VM, and that's it. It's because I don't require any support, so I don't need to pay.
I evaluated RedHat and Debian.
I have a personal experience with Ubuntu Linux in virtual machines.
The system can be deployed on-premises or on cloud, and this will depend on the testing required. We usually use the latest version of Ubuntu Linux.
I'm not using the system in a production environment, so its scalability is not something I care about.
I have not contacted technical support for Ubuntu Linux. I fix any issues myself, e.g. I go to their website and find the answers online.
I can certainly recommend Ubuntu Linux to other people who may want to start using it.
I'm rating Ubuntu Linux an eight out of ten.
