Ivan on the Server Side

Hello 👋 Ivan's here with a bunch of iximiuz Labs news and a portion of hands-on learning materials on Linux, networking, containers, Kubernetes, and eBPF. But before we jump into the main issue, I want to feature the sponsor of the month - Creem. Over the past few years, I've turned down numerous sponsorship offers, but this time I was glad to make an exception because Creem is the product I actually use and have been very happy with it.

But before we dive into it, I'm obligated to remind you about the ongoing Black Friday sale, and that it is the last (hence best) chance to opt in for the...
