Featured Reviews

Built a reliable cloud foundation that has supported flexible web applications and smooth scaling

Enterprise Cloud Operations Lead at a tech vendor with 10,001+ employees

Docker on Ubuntu can be improved because Ubuntu is not minimalist at all; it comes with a lot of software by default. This has led some individuals, including myself, to try using Alpine, which is more lightweight, allowing the container to run on a more lightweight operating system that potentially uses fewer resources and reduces costs. If Ubuntu were a little more minimalist, that would be good, but it's not really aiming for that since it intends to be the baseline. Also, Ubuntu moves very fast, possibly faster than other operating systems like Debian, which could demand operational heavy upgrades to major versions every couple of years if there are many applications running.

Massimiliano Adamo

Linux architect at European Commission

Has supported seamless migrations and enabled running complex data workloads securely

The best features Rocky Linux offers include clustering and all the packages from Red Hat.Rocky Linux has impacted my organization very positively because we migrated everything from CentOS and Windows servers to Rocky Linux. Everything is clear, with good packaging, and now it's version 9.6, which is very important for us due to security problems since we are in Europe. Rocky Linux is very good for security and other aspects. Since migrating to Rocky Linux, I've seen specific outcomes such as improved security because CentOS stopped the project, and security patches aren't being released. We need to maintain a system similar to Red Hat, which is very stable and has many features such as file system, topology, and containers.
