Thanks for the kind words. Even if you are not building a cloud service, I think it is good to understand how the underlying layer works and what are the knobs and the limits of the platform. I could see a use case where two or more processes need to run on one VM or a container, maybe for cost-saving reasons or specific architecture/security reasons, but need to be guaranteed a certain amount of resources and a certain isolation from each other.
