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.

Good compatibility and improvement needed in migration process
For long-term support, it has been good because in most enterprise environments, people still use Ubuntu Linux sixteen, which is quite obsolete now. Other enterprise versions do not support obsolete systems, so supportability is good in terms of Ubuntu Linux. For sustainability, it's quite a significant point of view for every organization. For us, Ubuntu Linux is the preferable way. For others, it might not be, so that is quite a subjective matter itself. The pinpoint of the problem is that they take time because they need specific information. We need to go to AWS first, and then they'll contact the Ubuntu Linux support team itself. This creates a two-way hop for us, which is why it's not that great. It's not really Ubuntu Linux's problem but rather the way we are accessing Ubuntu Linux. The migration part when migrating an application or one version of Ubuntu Linux to another is quite hectic. During the process, one or many applications might crash. That is something they could handle themselves, but I don't think that's something Ubuntu Linux will look into. During a migration project that I was handling, Ubuntu Linux was not completely compatible for the migration process from one application to another. This is an area they could improve in migrating from minor versions to major versions.
