I've been thoroughly enjoying "Designing Data-Intensive Applications" by Martin Kleppmann. It primarily deals with the current state of storing data (databases, etc) starting with storing data on one machine and expanding to distributed architectures...but most importantly it goes over the trade-offs between the various approaches. It is at a high level because of the amount of ground it covers, but it contains a ton of references to dig in deeper if you want to know more about a specific topic.
