The article does a great job of explaining the challenges they ran into with Kubernetes, and some of the things they tried... but I feel like it drops the ball at the end by not telling us at least a little what they chose instead. The article mentions they call their new solution "Gitpod Flex" but there is nothing about what Gitpod Flex is. They said they tried microVMs and decided against them, and of course Kubernetes, the focus of the article. So is GitpodFlex based on full VM's? Docker? Some other container runtime??

Perhaps a followup article will go into detail about their replacement.
