Reliable platform has supported long-term on-prem deployments and predictable OTA updates
If I consider how Debian can be improved, it could be more accessible in making newer software versions available for users who need recent features while still maintaining default stable behavior. While backports help, the workflow could be streamlined. The release cycle can feel slow for rapidly evolving tools, and better guidance around mixing stable, backports, and testing would help. Regarding hardware support, Debian can be improved by supporting multiple BSPs, making it more versatile in the embedded domain. Hardware support for new devices can sometimes lag behind, which is understandable given Debian's focus on stability. Clearer guidance on handling newer hardware or firmware would be beneficial.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best features Debian offers are that it is fast, simple, and long-term supported."
"Debian offers features that are best for my needs, including being open source, which allows for the implementation of many things and the use of a wide variety of open-source tools."
"Debian always provides zero downtime because all that is needed is to run pseudo APT upgrade and it fixes NGINX or the other packages that need to be fixed."
"Debian is the most straightforward and compatible option, which greatly simplifies our engineers' tasks."
"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."
"Debian offers excellent stability and reliability as its best features."
"Debian's best features are that it is very light and very comfortable for even older computers."
"Debian's stability helps me in my daily work because my work relies on stability; I'm trying to deploy production workloads, and Debian offers that stability for me."
"Flatcar's support is good, and the version I am using is stable and allows us to make needed changes."
"Flatcar's support is good. The version I am using is stable and allows us to make needed changes."
 

Cons

"What keeps it from being a perfect score is mainly the slow access to newer software and hardware support, as well as documentation that is somewhat fragmented for advanced use cases."
"Debian currently has some older packages that are not available in the latest version."
"About the features of Debian, of course, it is a slow distribution like many others."
"In terms of scalability, Debian on-premises is not very scalable because it depends on your hardware."
"I wish the company responsible for Debian would send communications about updates and new features to keep people informed and to give Debian the recognition and praise that it deserves."
"Customer support for Debian has been acceptable. We approached the Azure Debian support, and while it seems adequate, they need to improve somewhat."
"The stable kernel because it is going to be older and naturally stable does not always support brand new components such as CPUs or specialized GPUs out of the box, which can make it difficult to use there."
"It seems there should be a more deterministic way to do that. It does seem that you are running a lot of random install scripts to install things or relying on another two or three package management services, so there could be better software installation methods."
"The development teams could sharpen their skills. They should offer applications on the net."
