What is the difference between itunes match and using itunes icloud music library

[iMore Question]

They seem rather redundant.
Fundamentally I have lots of music (100,000 tracks) and want to listen to them wherever I am. That sounds more like itunes match (once they lift the limit to 100K with IOS9) than itunes cloud music library, where I would guess my music would take up lots of space and cost me lots of money?
