Well, Just as research was propelling me out of the closet, to proclaim that embedded (linux) systems are to become the backbone of the new clouds and clusters, somebody beat me to the punchline.
Linaro, which is pretty much the largest collection of deep pocketed folks in the embedded (arm64) game, has just announced debian and centos versions of embedded Linaro for the cloud [1]. They have a large cache of ported codes including but not limited to cephfs. That makes sense why docker, currently the commercial leader in containers, has subsumed Alpine Linux and it's OpenRC + Eudev platform for speed of deployment and HPC performance advantages. [2] Also, systemd issues abound in the cloud/cluster world. OpenRC's pathway to codes interfaced directly to cgroups is proving to be quite the performance advantage, particularly for specifically tuned clusters. Still, since gentoo supports both OpenRC and Systemd, I'm just not sure why somebody is not promoting gentoo as the best distro reference system for the cloud-of-Things and Hi-Performance-Clusters. Since I have been digging deeply into these and other related issues, Gentoo is everywhere, but just not getting the public recognition it deserves as a distro and cloud/cluster enabler. Perhaps all commercial vendors are actually scared of the power of the Gentoo? Some have projected that if you run your clouds and clusters directly on gentoo, you do not need vendors.... but more technical (gentoo) experts. Methinks so! enjoy!
