A few years ago I started to work for NASC which was an Academy Support Center for many vendors like Cisco, Oracle, Red Hat, LPI and more.
The focus of NASC was on improving ICT education. We mainly educated teachers and trained them to certify as CCNA, LPIC-1 etc.
There was a strong demand for IoT focussed education. It became clear that an affordable learning environment had to be created. This is why I started to work on IoT-Kit.nl.
