I'm using amazon, and there is docs everywhere to use xfs. Is xfs a software based raid? Is it fast?

XFS is not a RAID implementation. It is a filesystem. It does happen to have some nice tweaking ability. Some of those tweaks increase the performance of the filesystem when used in a RAID array. It is very fast...especially when configured properly. That's probably why Amazon recommends it.

XFS is a high performance file system originally developed by SGI. RAID would have to be done either in hardware or software at a lower level.
