It’s just my opinion and I’ll be happy to be wrong (because it means something better will have supplanted it). But I don’t think there’s a significantly-simpler, mature abstraction for doing container orchestration, than K8s. K8s’ main advantage/stickiness factor, is how abstract and modular it is. It’s an opinionated Kernel that gets most things right and has a huge ecosystem of tools built around this kernel. It has a very similar set of stickiness factors to Linux, imo, although the origin story couldn’t be more different of course. I think if anything replaces K8s, it’ll take a Linux-like shape. But K8s gets enough things correct (licensing, api, modularity) that it’ll be hard to replace it wholesale.
