text: , AltArch releases of CentOS 7 are available for the ARMv7hl and AArch64 variants of the ARM architecture, and plans exist for supporting other variants of the ARM architecture. ARM support is a community effort coordinated through the AltArch SIG. AltArch releases of CentOS 7 are also available for the IA-32 architecture and Power ISA (POWER7 and POWER8 chips).
  A Live CD version of CentOS is available at mirror.centos.org. A bootable Live USB image of CentOS can be created manually or with UNetbootin.
  CentOS images are also available on Amazon's EC2 cloud, in form of prebuilt and already published Amazon Machine Images (AMIs).
  Repositories
  There are three primary CentOS repositories (also known as channels), containing software packages that make up the main CentOS distribution:
  base : contains packages that form CentOS point releases, and gets updated when the actual point release is formally made available in form of ISO images.
  updates : contains packages that serve as security, bugfix or enhancement updates, issued between the regular update sets for point releases. Bugfix and enhancement updates released this way are only those unsuitable to be released through the CentOS-Fasttrack repository described below.
  addons : provides packages required for building the packages that make up the main CentOS distribution, but are not provided by the upstream.
