Question

Lately I have been reading about web crawling, indexing and serving. I have found some information on the Google Web Masters Tool – Google Basics about the process that Google does to crawl the Web and serve the searches.
What I am wondering is how they save all those indexs? I mean, that’s a lot to store right? How do they do it?

Thanks

Answer 1

I’m answering myself because I found some interesting stuff that talks about Google index:

• In Google Webmasters YouTube Channel, Matt Cutts give us some references about the architecture behind Google Index: Google Webmaster YouTube Channel
• One of those references, and from my point of view a worth reading, is this one: The Anatomy of a Large-Scale Hypertextual Web Search Engine

This helped me to understand it better, and I hope it help you too!
