For a "survey" of Galois theory of commutative rings, there is one book:
The Separable Galois Theory Commutative Rings by Andy R. Magid (1974).
which has a nice section summarizing the state of the development up to 1974.
There is also a more general book aiming at a topo-theory topos-theory style general Galois theory (although I haven't read it)it) including also a nice survey:
Galois Theories by Francis Borceux and George Janelidze (2001).
