Editing OpenSimulator Internals/ROBUST Services (section)

== Can Be Split and Load-Balanced ==

These services are stateless and can run on separate machines behind a load balancer such as nginx.

{| class="wikitable"
! Service !! Notes
|-
| [[OpenSimulator Internals/AssetService|AssetService]] || Stores and serves asset blobs (textures, meshes, scripts, notecards, etc.). Intentionally dumb -- no referential awareness. Two storage backends: database blob (default) or FSAssets (recommended above 50GB).
|-
| [[OpenSimulator Internals/InventoryService|InventoryService]] || User inventory. Folder tree and item references. Permissions live here, not in the asset table.
|-
| [[OpenSimulator Internals/GridService|GridService]] || Region map. Handles region registration on startup and deregistration on shutdown. Answers queries for region location and coordinates.
|-
| [[OpenSimulator Internals/UserAccountService|UserAccountService]] || User account storage. Name, email, user level, flags.
|-
| [[OpenSimulator Internals/AuthenticationService|AuthenticationService]] || Login authentication. Core implementations are password and webkey.
|-
| [[OpenSimulator Internals/GroupsService|GroupsService]] || Groups. Core groups service is not enabled by default. External XmlRpc/Flotsam groups service is the common alternative.
