There Are Two Bets Being Placed – Kubernetes vs. Other Schedulers (Nomad, Mesos, others)

There Are Two Bets Being Placed – Kubernetes vs. Other Schedulers (Nomad, Mesos, others)

Background Are you both impressed with and intimidated by Kubernetes? It’s understandable. Kubernetes is moving fast, it’s super powerful, sophisticated, has a large upstream community, and tons of vendor interest, a huge user base, and is moving at the speed of light. This can make it intimidating. In short, it looks a lot like Linux

Testing With Podman – Complete Uninstall/Reinstall

Testing With Podman – Complete Uninstall/Reinstall

Background Sometimes it’s necessary to uninstall completely, and reinstall when testing software. This is something I have been doing with podman on RHEL 7.6 since about 6AM today 🙂 I figured it was worth capturing the instructions I have developed while testing user namespaces and rootless containers. This could make your life easier too. Complete

Learning Container Engines by Demo

Learning Container Engines by Demo

Background So, this morning I had a call with some customers who are using Podman in RHEL 7.6 Beta. We got into a pretty good discussion about what a container engine does. Many people have tackled this subject before – Liz Rice has a great talk where she builds a container engine from scratch. I loved

Hardware 1.0 vs. Hardware 2.0

Hardware 1.0 vs. Hardware 2.0

I’ve seen a lot negative reactions to the terms multi cloud and hybrid cloud. I would argue, that’s because we are framing it wrong. It’s really Hardware 1.0 and Hardware 2.0. In Hardware 1.0 Dell, IBM and HP all tried to sell us fairly similar servers. We typically bought these servers, but we could finance
