This kernel provides the core functionality any OS needs, controlling how data is processed and parcelled out into memory, how the system handles files, how it interacts with devices plugged into the computer and other fundamental tasks. Some focus on simplicity and usability, such as Ubuntu, Linux Mint and Elementary OS; others on security, such as Tails; others on providing powerful tools for technical experts, such as Debian and Gentoo.

Red Hats made a multi-billion dollar business out of supporting open-source software and today owns organizations responsible for everything from integration services for the open-source cloud platform OpenStack through to creating the KVM hypervisor. There is a shift in thinking, however, with 29% turning to open source because it gives them access to the latest innovations - a reference to the crucial role of open-source technologies in supporting microservices and containers in the cloud, or its use in the burgeoning field of machine learning.
