Techopedia Explains OpenBSD
Uses of OpenBSD are fairly obscure in the tech world, mainly because the use of the licensed operating systems is so prevalent. For example, most consumer systems and even the vast majority of business systems utilize a Windows operating system or some licensed version of a Linux or UNIX system.
However, OpenBSD has been useful in creating a community around the use of an open source product to run disk or container images with a UNIX-like capacity.
