heroku is a PaaS, it could be running containers internally, you wouldn't know. docker, k8s and the other tools are just building blocks of a PaaS, you are comparing oranges to a full course meal.
Sure, but the point is that by running your own K8S you're running a cloud provider. Which is fine, if your business is being a cloud provider. If not, let someone else do it, they'll be better at it.
Genuinely curious what you were doing. Renting your own racks in a DC, providing reliable networking, paying upfront for all the servers and then hiring staff for just managing all this bare metal is insanely expensive for a startup. How is not using cloud a cheaper option?
We're renting bare metal servers from Hetzner. It's multiple times cheaper than AWS. We have lots of data, and to handle it with no problems our DB server has 512 GB of RAM and 24 cores (AMD EPYC). How much does it cost to have a comparable server on AWS? More than $2k per month, last time I checked.
We bootstrapped the startup and I'm based in a much cheaper area than SF or NY (Eastern Europe, actually). I can hire a decent developer here for $2k per month.
Okay so you're still using Cloud service but with a different layer of abstraction. It's not the same as on-prem Bare metal which usually people refer to as "not using cloud"
This is to me a very scary comment. It says "we have no idea how computers work". Source: run a service on bare metal in a rack in a DC that I haven't entered in a year or more.
What is your scale? How much does it cost? What happens when your rack or DC goes down? All of this is not worth it for small-mid size companies. This is why the cloud took off in the first place. The revenue of AWS, Azure, GCP speaks for itself.
