I see, so you are using PaaS and I was talking about IaaS offerings. The term cloud is so vaguely defined that it can mean so many things.

If the PaaS works for your scale and budget then it’s perfectly fine. I just want to mention that it is probably no longer the case for scaled-ups.

You're right, I should have clarified that IaaS is exactly the stuff you want a cloud provider to take care of for you, and that's where many of the benefits come from.

But IaaS has been around for nearly 20 years now, and containers for at least 10 years, so I tend to assume people have got that message by now, especially on HN.

Re scale, you can run pretty high scale on managed Kubernetes clusters. E.g. GKE supports up to 15,000 nodes per cluster, hosting over 3.8 million concurrently running pods. Multi-cluster ingress is also supported if you need to run multiple clusters.
