setns.live 005 - xinetd, the first serverless - Kris Nóva & Spencer Krum

Join Kris Nova (Sysdig) and Spencer Krum (IBM) while they investigate the first serverless: xinetd

xinetd is a Linux superserver used back in the 2000 that can launch services on demand to keep the machine resource usage under control. It contains several similarities to current serverless solutions like the popular AWS Lambda.

All the test are performed on a Raspberry Pi running arm64 Manjaro.
