Eli5 how can google host so much information?



With websites being hosted on server computers how can a website as large as google for example host so much information?

In: Technology

Google uses a distributed architecture spread across many thousands of server computers. This allows them to serve results (and ads) to millions of users at the same time.

Google doesn’t necessarily host those individual websites (although google does offer website hosting via it’s cloud services).

If you are talking about Google search it has just “indexed” those sites, that is to say created a database of the sites that you can search. Although there may be billions of sites the data to search is relatively much smaller than the sites themselves.

The combined data of this, maps, street view, etc. us still a high amount of data though, and Google owns massive data centres to store and serve this information.
