I really worry about cost in this future of leaning on something like ACI/Fargate to actually run the containers. An m5.large instance (2vcpu/8gb) costs $70/mo on-demand ($44/mo with a 1 year reservation). A similar Fargate runtime costs $146/mo. A b2ms Azure instance (2vcpu/8gb) costs $60/mo on-demand ($39/mo 1 year reservation). Azure Container Instances at a similar provisioning level costs $176/mo by my calculations. That's not a small difference. That's, like, 3x. Point being, I love virtual-kublet from the perspective of a scale-up just trying to get a product out the door. But for established companies, I still think the core idea of a container on a VM you control is going to rule. Fortunately Kubernetes allows amazingly easy flexibility to switch, and that's a reason why it might be the most important technology created in recent history.
