For consumer applications, you are limited by the ecosystems, such Android or iOS or Windows, so you can't choose kernel anyway.

For cloud applications, what is more important is the system architecture, not the kernel. If we assume docker is the preferred way to deploy an app. We only need very limited features from kernel:

- If I specify the CPU and RAM requirements, the kernel simply allocates them to the container. There is no need for complicated dynamic scheduling and balance.

- Network within the same data center has much lower latency than hard disk (<<1ms vs 10ms). We will be much better of using network storage or database.

- If we assign network address to each container, the kernel can deliver network packets to container, and the container uses its own CPU and RAM to process the network traffic. This will avoid the situation that kernel spend a lot of CPU/RAM to process network traffic for all containers and find the correct way to charge the cost.

If we do all above, there is not much kernel features are needed by cloud applications, as such features will be replaced by cloud services like cloud storage/database. It will make develop and deploy cloud services easier and more productive.
