Sure but the context is personal projects or portfolio/small business sites. A VPS on a discount provider such as Hetzner or OVH costs around 3-4 USD/EUR per month. A redundant VPS (two VPS and Ceph) costs 10 EUR on OVH. Not to speak about the complexity of setting up and running k8s. You'll be needing a second k8s development/testing environment for staging as well. So, no, I don't think k8s makes sense economically.
