The book assumes that you know nothing about the topic other than that you presumably have put up some web-pages at one point in your life. You can read the book even if you don't know what IP or DNS stands for. Unfortunately, this is also a huge time-waster for most of the actual audience because people who know the existence of the concept "load balancing" actually *do know* quite a lot of background on the topic.
I could tolerate being explained things from the basic concepts up but what really frustrates me is the chitty-chatty style, including lots of sentences that provide zero information, and lots of unnecessary words in those sentences that actually include information. The book could easily be trimmed down to 30% or at least 50% of its current size with no loss of information. This would more than double its value. The contents of chapter 8, 9 and 10 are 80% identical, explaining how to use the same service but ignoring that an identical explanation has already been provided in the previous chapter. Chapter 6 is a complete waste, I did not buy a book on load balancing in order to be spoon-fed general project management wisdom.
A merit of the book is that it's hands on, many of the chapters provide a step-by-step walk through of configuring the software packages it introduces. Many other books with "load balancing" in their title don't have this part.
-- sqid proxy
-- mention of memcached and what it is good for
-- how DNS based balancing works and disadvantages
-- what a content delivery service is with an example of configuring one
-- a comparison between apache httpd and nginx performance
-- the use of IPVS for load balancing network traffic
-- running MySQL in replication mode
-- high availability via IPVS, ldirectord and heartbeat all with hands-on examples;
-- SSL termination
-- some chit-chat about cloud and IPV6, neither chapter containing enough substance to be really useful.
One big omission from the book is coverage of layer 5-7 load balancing. This should have been much more useful than the boring "jokes" and project management preaches.
I read the electronic version and found no issues with it. For the information of those who have had bad experience with kindle versions of technical books.
The book could make some use of copy editing to reduce the number of typos, of the type where the word is actually present in a dictionary but a different inflected variant would be needed in the sentence, or typos like "as" vs. "is."
My heart is bleeding to give 3.0 for the effort that went into writing the book. My actual rating is 3.5. The -1.5 is for the waste of my time with verbosity and irrelevant contents and for the load balancing topics that are missing.
I still do not regret having read this book but will also need to read the older "Server Load Balancing" and "Load Balancing Servers, Firewalls and Caches," both of which seems to provide more depth (but no hands on).
Will appreciate recommendations for better books on the topic.
