Microsoft’s Linux Strategy

When Microsoft first embraced Docker and containers some years ago, no
doubt people thought it was trying to nab some of that
“virtualization-lite” action for its own Windows platform--at least I
know I did.

But with the release of WSL 2, which includes a full Linux kernel in
Windows, it looks like this strategy has changed
<https://www.theregister.co.uk/2019/06/18/the_future_of_docker_on_windows_is_linux_says_docker/>:

    The Docker news is of no interest to developers using Windows
    Containers, but there are not many of them. At Microsoft's Build
    conference last month, Gabe Monroy, lead program manager for the
    Azure Container Compute team, was asked whether Windows Containers
    are for legacy and Linux Containers for new projects. "I think that
    is a fair description," he said, demonstrating how the company's
    thinking on the subject has shifted.

It seems Microsoft is now pushing the concept of develop on Windows,
deploy on Linux. It is clearly hoping that those Linux deployments will
happen on its Azure cloud, and so it still profits that way.

Also, WSL 2 actually makes for worse Linux-Windows integration compared
to WSL 1, which emulated the Linux APIs on top of Windows:

    Similarly, WSL 2 makes life better for developing Linux
    applications on Windows, but there are downsides. Running Linux in
    a VM as opposed to redirecting system calls is better for
    compatibility but inherently worse for integration. One aspect of
    this is that in WSL 2 I/O performance to files within the Linux VM
    is much faster, but I/O performance between Linux and the host is
    worse. Another is that WSL 2 has no access to serial or USB ports.

Seems to me the obvious way to fix this, at least partially, is to flip
things round, so instead of virtualizing Linux on top of Windows, you
virtualize Windows on top of Linux. Then both your development and
deployment platforms become fundamentally Linux-based. How long before
that happens?
