I think the key message here is that knowing when to use a given technology (e.g: Kubernetes) is good - but it's more important to recognize when not to use it.

Don't get me wrong, I love Kubernetes, but I agree w/ Kelsey here - if you're running Kuberenetes on top of an orchestrated hypervisor and not using it to the fullest, you're just losing on performance. I think we generally forget how bare metal (and scaling vertically) can sometimes be the right approach, like illustrated in this Let's Encrypt blog post: https://letsencrypt.org/2021/01/21/next-gen-database-servers https://letsencrypt.org/2021/01/21/next-gen-database-servers
