What is the Linux Foundation ?
- Vendor Neutral , non profit organization
- Supports open source through:
- Financing
- Intellectual resources
- Infrastructure services
- Events and Training

There are hundreds of Linux distributions.
In this course we will focus on the below distribution families:
- Red Hat Family Systems (including Centos and Fedora)
- SUSE Family System (including openSUSE) - OpenSuse Leap is what I am currently using
- Debian Family Systems (including Ubuntu and Linux Mint)

The Red Hat Family

• Fedora is an upstream testing platform for RHEL
  NOTE Literally think of upstream and downstream like a waterfall or stream
• Uses dnf, the RPM based package manager used to install, update, and remove packages

• RHEL is widely using in enterprises that host their own systems

  Currently:
  Fedora > Centos Stream > RHEL

  Originally:
  Fedora > RHEL > Centos

The SUSE Family
- SUSE (SUSE Linux Enterprise Server or SLES) and openSUSE has a similar relationship between RHEL, CentOS, and Fedora

• SLES is upstream to openSUSE
  SLES > openSUSE
• Uses Zypper - RPM based package manager
• Includes YAST
• SLES widely used in retail

The Debian Family
- Debian distribution is upstream for many other distributions, including Ubuntu
- Ubuntu is upstream for Linux Mint
- Debian > Ubuntu > Linux Mint
- Debian is pure open source - not owned by any corporation
- Strong focus on stability
- Uses DPKG based APT package manager
