Quick and incomplete summary: In recent years Lidl invested heavily in cyber security and cloud computing, first for their own independent infrastructure, but they’re already selling their security and cloud services to other big companies. The video makes the point that eventually they could become a proper competition for Amazon AWS and other services.
Maybe a bit premature for amazon competitor but definitely an alternative
Couple of big companies like banks are already using their services because they’re hosted in Germany and Austria and comply with GDPR, I think that’s a huge selling point. Question is if they’ll go public and make their services available for everyone, not just big businesses.
