What Is JeOS (Just Enough Operating System)?

Just enough operating system (abbreviated JeOS) is an operating system development concept that refers to developing customized, stripped-down systems that suit the needs of specific devices or hardware setups.

The “less is more” attitude allows developers to design operating systems that perform faster, more stable, and more secure.

Common JeOS use cases include ATMs, e-book readers, kitchen appliances (refrigerators, coffee makers, etc.)

The JeOS approach is also used for designing operating systems for bare metal servers.
