All Things Open 2025 Day 1

All Things Open is a conference in downtown Raleigh. Celebrating their 13th year, I've attended a couple over the years. Before covid, the last one I attended was standing room only. The conference kept going through covid and seems to be in full swing.

Here's the Monday schedule. I didn't make it out Sunday, though hope to next year.

Before the keynotes, did a run through of vendors. Discovered a local keyboard maker, Keebio. While I'm content with the mac chiclets, I'm keyboard curious.

The keynotes were decent. The one on going into the third decade of open source, brought back the memories of working before open source was more accepted. While working for different companies, I've always worked with some open source, early days of sendmail and apache. Microsoft and open source is natural these days. At one time, not so much. Of course, AI was a topic of a few.

The sessions started off a bit rough. Settled into a room and the presenter didn't make it. Things happen. Accelerating Incident Response with OpenTelemetry and MCP: Building Agentic Observability System I took advantage of the quiet room to catch up on things.

Next session I was looking forward to. I spent some time over the weekend reviewing karmada documentation. I've questioned the need for multi-cluster deployments, however, coming around to some value in being able to do such. The session is actually two topics in one time slot.
Deploy Once, Run Anywhere: Simplifying Multi-Cloud Kubernetes with Karmada
The presenter talked through the documentation, for the most part, tossing in their experience along the way. I could attend sessions like this one all day. Good stuff.
Forget Everything You Know About Building Software
The presenters told a story of packaging software, leading to nix as the answer and they were a company that provides support.

Sessions notes:
A Tug-of-War: Performance vs Security Tradeoff in Containers — security of the containers
lmbench — test container performance 

Use of kata containers, architecture of kata containers
kata container OCI compliant
Testing was done on cilium and calico. Used iperf for the tests. Cilium tested better with virtualization.
Kata container limitations, more memory and more time for start up
VM template to speed up boot times

Beyond the Mesh: Custom North-South Traffic Control with Envoy
2 guys from Fidelity and how they moved from paid gateway to Envoy
Lots of words about a good gateway replacement.

At the end of the day, I did a lap through the R!OT demo setups. They were setting up for a long evening. Didn't stay for the show.
