Sorry if this is a copyediting item but the end of this section says " [...] know about these in order to design a system that will degrade gracefull [sp] in the event of some catastrophe (like that earthquake we mentioned)." There is no prior mention of an earthquake or natural disasters in the text. There are some future mentions a few pages later in the text.

I'd to add the datacenters locations (3.1) seems outdated. According google https://cloud.google.com/about/locations/#regions-tab they have added two new regions in Singapore and Australia. Also the number of cities does not match.

According this,


also AWS and Azure info should be updated.
