   >in what way can smaller players federate with ATProto or how the structure allows federation.

   Each of the pieces I've described (PDS, Relay, AppView) implement the protocol specified at https://atproto.com/. The structure allows federation by design — a Relay will index any PDS that asks to be indexed; an AppView will choose the Relay it wants to get the data from or index PDS's directly; anyone can make their own AppView for an existing or a new app.

   Additionally, Bluesky's reference implementations of each piece are open source. So people run them the same way you would usually run software -- by putting it on a computer and exposing it to the internet. To run a custom PDS, you can either use the Docker container provided by Bluesky (https://github.com/bluesky-social/pds) or implement your own (e.g. https://github.com/blacksky-algorithms/rsky). Ditto for other pieces.

   >Reading through it, it just sounds like sharding/scaling for a centralized service that's meant to be owned and provided by a single entity.

   You're right in that the goal is to make it on par with centralized services in terms of UX and performance/scaling. However, it is decentralized.
