Back in 2018, we taught those DevOps concepts and implemented unbreakable pipelines for cloud-native delivery projects. Last week we kicked it off with a three-hour virtual hands-on workshop. The initial plan was to do it onsite in Ohio, but – I guess I don’t have to tell you why – we decided to start virtual first.

Before booting a compiled Linux kernel image on actual hardware, it can save us time and potential headache to do a quick boot in a virtual machine like QEMU.
