The first time I heard about 21unity was when I read the announcement: 21unity Joins OpenPOWER Foundation. I immediately became interested in the company, as it combines two things I am interested in: POWER and open source. Among others 21unity has its own cloud based on the POWER platform and provides Nextcloud as a service. I tried to refresh my German knowledge and read their website, but the more I read the more interesting it got and the more questions I had.
