I just found that there is a product called ArcGIS spatial data server.
And reading about it, found it is very similar to ArcGIS for server (just subset of it).
So, what is the difference between the two?
is it just a subset of the full server, so maybe it is cheaper?

If ArcGIS Server and ArcGIS Spatial Data Server (SDS) actually share any programming code is something only ESRI can tell, so your question of "whether it is a subset of the full server" is unanswerable... ESRI presents them as two separate products.
From a functionality point of view, SDS does not support any of the advanced geodatabase functionality like topologies, network datasets, parcel fabrics etc. So if your goal is to build a geodatabase incorporating any of this, and create a webapplication having some of this advanced functionality, than SDS is NOT the way to go, you will need ArcGIS for Server.
In addition, Spatial Database Server was primarily designed to access and serve editable Feature Service layers from non-Geodatabase repository containing Spatial databases with native spatial types, although you can access and serve Geodatabase layers in a read-only mode - and as Simple Features only - too.
Please note it also is primarily targeted at serving web Feature Services, not Image Services, which it can't even create according to the documentation I saw. IDK, but performance is likely not to be on par with fast cached Image Services of the same data.
