Cloud Ops Lead at a tech vendor with 10,001+ employees
Lightweight platform has reduced cloud costs and has kept long‑running web apps reliable
In my opinion, the best features Debian offers include its stability. The stable branch really is stable because once it is configured, I understand you can run it for a very long period of time without needing to reboot or update any of the components. That is really good when you want an application to be extremely stable and not go down, and you are happy using slightly older components. I also value the fact that Debian is open source, so it is free. That is very useful, and it has a big development community that builds it. I understand there are tens of thousands of software libraries which work with Debian from the apt package manager, APT, and also it is very lightweight, which I find to be good as well because that helps with cost savings. Debian's lightweight design benefits my organization because it does not come with bloatware, minimizing RAM usage. Because of that, we can choose cheaper EC2 instances. You do not have to have as powerful RAM, which makes things cheaper, and also because it does not come with all this bloatware, it also makes it faster. So it is very efficient. Debian positively impacts my organization by allowing us to utilize a much more lightweight operating system with Amazon EC2 instances, which greatly reduces costs because we can use EC2 instances with lower RAM. Cost savings are good. Debian is very well known across the industry, so different engineers from different teams know how to use it. Using the APT package manager is a common skill for cloud professionals, which makes it good, especially if you are hiring individuals into the company, because at least you would expect they have some type of background using Debian. I do not know exact measurements, but I would expect we could save at least 10% of costs with EC2 instances just because our memory and CPU requirements would be lower because Debian is lightweight. So it would save cost to some degree.

Long-term server platform has supported secure banking operations and simplified virtualization
Oracle Solaris is a very good operating system. Most of the time, we do not need to change or replace any configuration. If at any point in time we need to change something, it is really simple and a user-friendly environment. Although it is a CLI, Oracle introduced a GUI environment with Solaris 11.5. Currently, 11.5 has the operating system GUI as well as the CLI. The technical persons working on the operating system most of the time prefer to work on the CLI. It is actually really good and easy to use. As it is a server-level operating system, most of the time you do not need any extra features in the operating system because you are not using the operating system on home machines, desktops, or laptop machines. The extra features are not needed if we are talking about the enterprise level or an official operating system.
