Editing Personal Data Server (PDS) (section)

==== PDS Entryway ====
For large-scale PDS hosting operations, an "Entryway" service provides centralized account distribution, session management, request routing, and OAuth authorization. Users of such services don't need to know which specific PDS hosts their account - they simply interact with the entryway domain. For example, Bluesky's PDS Entryway service (at <code>bsky.social</code>) distributes users across multiple physical PDSes while presenting a single logical service to users and applications.

When a user creates an account through an entryway like <code>bsky.social</code>, the service assigns them to a specific PDS behind the scenes. The entryway then handles routing requests to the appropriate server and manages authentication across the entire service. This architecture allows for efficient scaling while maintaining a simple user experience.
