It feels like Ms Frazelle's essay ends abruptly. I was looking forward to the other use cases of non-Linux containers. I think most people are considering these OS-level virtualization systems for the same or or very similar use cases: familiar, scalable, performant and maintainable general purpose computing. Linux containers win because Linux won. Linux didn't have to be designed for OS virt. People have been patient as long as they've continued to see progress -- and be able to rely on hardware virt. Containers are a great example of where even with all of the diverse stakeholders of Linux, the community continues to be adaptive and create a better and better system at a consistent pace in and around the kernel. That my $job - 2, Joyent, re-booted Lx-branded zones to make Linux applications run on illumos (descendent of OpenSolaris) is more than a "can't beat them join them strategy" as it allows their Triton (OSS) users full access, not only to Linux API and toolchains, but to the Docker APIs and image ecosystem and has been an environment for their own continued participation in micro services evolution. Although Joyent adds an additional flavor, it targets the same scalable, performant and maintainable cloud/IaaS/PaaS-ish use case. In hindsight, it's crazy that I worked at three companies in a row in this space, Piston Cloud, Joyent, Apcera, and each time I didn't think I'd be competing against my former company, but each time the business models as a result of the ecosystems shifted. Thankfully with $job I'm now a consumer of all of the awesome innovations in this space.
