Adding to the already good recommendations on this thread:

- Interconnections: Bridges, Routers, Switches, and Internetworking Protocols (https://www.amazon.com/Interconnections-Bridges-Switches-Int...)

It covers a broader range of topics than some of the other books mentioned here and helps with an understanding of where existing tech comes from and why. Also it covers topics that you don't necessarily need to know if you're only operating in a cloud environment, but that help to understand what is going on in those far off data centers.

After spending a lot of time trying to find resources to get up to speed on this networks domain for work, those are the best resources I've found.

The book that I recommend for Networking, and that has been recommended to me by every fulltime NetEng I've ever asked, has been Interconnections.

Yes, the material is a bit dated. Yes, it won't give you the ins and outs of what you need to know. What it will give you is the why and from there you can figure out everything else you need to know.

Radia Perlman also wrote a great (and fun!) book on networking: https://www.amazon.com/Interconnections-Bridges-Switches-Int...

Digging through my piles of books, it's this one, outdated if you're interested in current stuff.
