DevOps is a huge scam.

Whoever sold companies maintenance-free cloud is God-tier marketer, they would be able to sell fire extinguishers in hell.

First, the platform is constantly moving, keeping up with all the updates for Kubernetes/CNI/Ambassador/Calico/kube-proxy/wtf/foo/bar/etc requires a huge team constantly peddling the boat; and if not updating in time - eventually everything will suddenly break when AWS deprecates old Kubernetes version (1.23 in EKS has just 1 year and 2 months (!!!) of support) or whatever else. At least they don't deprecate services that often.

Second, all other tooling either suck, or expensive as a Boeing. DataDog/Splunk/NewRelic/Grafana? Data centers were built for the monthly prices of these tools not so long time ago. But, capex vs opex, what stupid software engineers knows (though, it's hilarious to be present on a meeting with an agenda "reduce cloud costs").

That's all really.

On the bright side, when the team is solid and really care about the product and build it in a cloud-first manner (with understanding of all the requirements, caveats and limitation) - it can be rock solid, stable and fast platform.

To bad it's incredibly easy to implement some impressively wrong architecture (much more easier than f'up single-server architecture).
