Episode notes
Kubernetes Is The Cloud Traffic Controller
- Kubernetes acts as the traffic controller for containerized apps, scaling resources with demand to keep services running smoothly.
- CAST AI sits on top of Kubernetes to automatically optimize resource allocation and reduce waste while preserving performance.
Early Passion For Coding And Entrepreneurship
- Leon Kuperman shared he loved coding from a young age and wrote a letter in grade school saying he hoped people would buy his software.
- His early passion led to years of hands-on experience before founding companies like ZenEdge and CAST AI.
Learning ML Via Coursera Led To Exit
- Leon described using Coursera's Andrew Ng course to self-teach machine learning around 2014–15 and applying it at ZenEdge.
- That work used ML to detect malicious web traffic without hard-coded rules and ultimately led to an acquisition by Oracle.
