Any Plan for distributed dedicated server

While developing FPS game of big open world (e.g 64km * 64km, even the boundless world), the Dedicated Server is a huge bottleneck because it’s very hard to handle such a big scale physical simulations, real-time computing and networking on a single machine!. In order to solve this problem completely, Can spread the burden of dedicate server to lots of machines?, like many of the cloud applications such as google spanner which can dynamically expand and shrink! I want to known the Unreal Develop team have any plan for this feature?

SpatialOS I know, it need lots of engine modification and It’s difficult to integrated to original UE4,

You don’t really need to do any engine modification by yourself, just build the one Improbable provides:
