Skupper + InstructLab: controlling and protecting AI (act 1)

The story behind this solution pattern

Growing demand for AI-driven applications brings a hard problem: how do you deploy and operate AI models securely in environments that need strict data protection, while those models still have to be reachable by public services? That need became clear while building a local AI chatbot meant to handle sensitive and proprietary information — we needed a design that kept the model inside a protected environment.

TCP/IP protocols: a complete introduction

ARPANET and the origins of TCP/IP

The story of TCP/IP starts in the late 1950s, at the height of the Cold War. The U.S. Department of Defense (DoD) wanted a command-and-control network that could survive a nuclear attack. Military communications at the time relied on the public telephone network, which looked fragile: rigid hierarchy, little redundancy.

Early research and Paul Baran’s contributions

Around 1960, the DoD hired the RAND Corporation to look for a solution. Paul Baran proposed a highly fault-tolerant distributed design that used digital packet switching instead of analog signals. Large carriers like AT&T resisted at first, but Baran’s idea laid the groundwork for modern resilient networks.
