Distributions

For Host Machine

RHEL/RPM-based:
```
AlmaLinux, RHEL (Production) > CentOS (Bleeding edge) > Fedora (Development)
```
Package Management: DNF (Old version: YUM)
- AlmaLinux: A free, open-source, community-driven 1:1 binary compatible fork of RHEL. It was created as a stable and supported alternative to CentOS, which shifted its focus to CentOS Stream.
- CentOS: A rolling-release distribution that exists between the upstream development (Fedora) and the downstream stable distribution (RHEL). It provides a preview of what the next version of RHEL will look like.
- Fedora: Sponsored by Red Hat and serves as the upstream source of the RHEL. It's known for its innovation and provides the latest software packages.
- Red Hat Enterprise Linux (RHEL): A commercial distribution targeted at the corporate market. It offers long-term support, strong security, and professional services.

cat /etc/redhat-release

Debian-based:

Debian (Production) > Ubuntu Server (User, Friendly, Bleeding edge)

Independent:
- Alpine: It's known for its small size. Alpine Linux uses musl libc instead of glibc used by most Linux distributions, so if your application depends on glibc, it may not work correctly on Alpine. In general, most C libraries and programs on Linux do depend on glibc as it provides the standard C library functions.
- Arch Linux: Simplicity and user-centric design. However, it's not commonly used in Docker images due to its rolling release nature, which means it may introduce breaking changes that can affect the stability of your Docker containers.
