I run workloads on Kubernetes and I would not choose it for most of the projects I am asked about.

What you are signing up for

An ingress controller, certificate automation, a secrets story, autoscaling configuration, resource requests nobody sets correctly the first time, cluster upgrades on the provider’s schedule, and a networking model that will produce at least one outage nobody understands for a day. All of that is learnable and none of it is your product.

When it is the right answer

• Many teams needing self-service deployment without a platform team as a bottleneck.
• Genuinely variable load where bin-packing saves real money.
• Workloads that need scheduling primitives, like batch jobs with resource affinity.

If none of those apply, a managed container runtime will do the job with a fraction of the surface area, and you can migrate later when one of them becomes true.
