This is just what I wanted, something that explained me all this amazing world of distributed computing and networking.
If someone could suggest a good book, that'd be interesting too (I've been looking at Unix Network Programming and The TCP/IP Guide for starting with networks).
That depends on what level of book, and what you want to learn from it. On "how real distributed systems are built", there isn't a really good book available in my opinion. I liked The Datacenter as a Computer, but it's scope is fairly narrow and is more focused on global infrastructure issues than software design issues. On the math behind distributed systems, Nancy Lynch's book Distributed Algorithms (http://www.amazon.com/Distributed-Algorithms-Kaufmann-Manage...) is my favorite, but it's getting to be quite out-of-date.
Absent a book, there are a lot of great resources online. High Scalability(http://highscalability.com/) has a good amount of quality links to distributed systems content, and some editorial content of varying quality. In general, it's a good site to follow if you're interested in how distributed systems are being used in industry. I also like to follow Aphyr's blog(http://aphyr.com/), Daniel Abadi's blog(http://dbmsmusings.blogspot.com/), and Henry Robinson's blog(http://the-paper-trail.org/blog/) and Peter Bailis's blog(http://www.bailis.org/).
The Architecture of Open Source Applications books[1], while eclectic, seem pretty good from the chapters I've read. They have a few chapters about distributed systems--HDFS, Riak, and a chapter about "Scalable Web Architecture and Distributed Systems" (haven't read it).
