I weep for Solaris Zones and FreeBSD Jails. Granted I don't really have much experience of them, I do have some experience of containers on Linux via Docker but also in constructing a minimal container runtime in C (not OCI compatible or anything), but my point is there was a lot of work in this area before Docker and especially in the case of Zones, freely available today in illumos distributions, are completely overlooked. I mean I could be completely missing something here, but Joyent for example seem to have made some really good innovations with Manta, i.e. spinning up containers to run UNIX pipeline equivalent jobs directly in the cloud on the data, but as with illumos vs Linux, Zones vs Docker and Joyent vs AWS/GCP/Azure, it seems to me a david vs goliath kind of battle, even if the tech is better.
As do I. Solaris in general and Zones in particular are so much better. There just wasn't an ecosystem around it. Solaris was too late to make the shift to open source. It might not matter; had they done so "in time" it might have killed them anyway!
