True decentralized architecture?

[shapirus]

I read https://github.com/admiraltyio/admiralty/blob/master/proposals/decentralized.md and was wondering if anything considered in this document has ever been implemented.

It would be very nice if we could achieve true decentralization without a single central master scheduler and thus a SPOF-free system, which would not only improve reliability, but also simplify management, as multiple equivalent clusters could be launched using the same configuration template (think terraform etc.).

Do we still have the star (one master - multiple slaves) topology as the only option?
