Like Fedora, CentOS is a community developed distribution of Linux, originally based on the commercial OS Red Hat Enterprise Linux. In light of this, the developers behind CentOS 7 have promised to provide full updates for the OS until the end of 2020, with maintenance updates until the end of June 2024 – which should save the trouble of performing a full upgrade on your server in the near future.
You can avoid unnecessary packages by installing the ‘minimal’ ISO from the CentOS website, which at 680MB can fit on a single CD. If you’re eager to get started, the site also offers preconfigured AWS instances and Docker images.
