Software Engineer's fallacy: if all you have is software/programming skills you start to look for an open source linux based solution to holding wooden boards in place, one that doesn't vendor lock you into the iron ore.

With Windows vs Linux the premise was you install absolutely free software on a computer you already own and you end up with a superior computing and programming environment.

With k8s - you switched to it, now what? You have to buy server hardware, rent or build a room, run wires for electricity and broadband, build cooling, physical security, etc etc etc. You will stop paying hourly rate to Amazon, but all the upfront and recurring costs will chew into that saving and you'll question whether it was worth the drill. Foremost, it will all take days and weeks, but with AWS it takes intolerable 20 minutes to spin up the k8s control plane (did I remember the term right?)

Even if you do all of that and blog about your great success, what's your plan for when it goes viral and visitors flow in to leave accolades on your visionary move?

With AWS, you could just spin up more servers to deal with extra traffic. With your own datacenter, you'd have to order new servers, perhaps from Amazon's same day delivery...

But many companies and workloads don't "go viral" because they aren't VC funded social networks. They're big, stable companies in mature markets where competition means everyone is always looking for cost savings.

If your workloads are predictable and you care about cost savings, AWS/Azure/GCP aren't great deals. They're expensive; why do you think these firms love them so much. AWS made Amazon profitable for the first time ever. These are the new big platform plays but many firms don't need them. Modern hardware is reliable and if you don't need thousands of machines or really complex proprietary services (AI accelerators etc) the overhead of renting a bunch of dedicated machines in a cheap provider isn't that high.

I'm not sure that's the choice. You can run kubernetes in the cloud, can't you? e.g. EKS on Amazon.

So you also agree that there's no standoff between AWS and K8s, unlike an article titled "'AWS vs. K8s' Is the New 'Win vs Linux'" would suggest?

It also talks about building a personal data center quite a few times (at least that's how I read it).

K8s is likely to replace EC2, ECS, and all other unusable amazon bloat to become the default AWS API. But it's not going to damage AWS, it's going to enhance it and become part of it.

Running k8s in AWS (and gcp, and on-prem) is exactly what we do and we're really happy with it and have avoided lock-in. We recently moved a bunch of k8s-in-AWS hosted stuff to gcp and it was seamless.
