is it really NIH if they made no attempts to build anything resembling a k8s clone themselves? They decided container orchestration is just not a major problem for them. Its a completely different model, they're embracing immutable infrastructure principles instead of the k8s model (container versions in their stack are bound to the lifetime of the ec2 instance they're on). This reads as simply a choice to have less complexity in their stack, which I think is admirable.
