Google data center security Video

This video tour of a Google data center highlights the security and data protections that are in place at Google data centers.

Rather than storing each customer’s data on a single machine or set of machines, data from all Google customers (consumers, business, and even Google’s own data) is distributed amongst a shared infrastructure composed of many computers located across Google’s many data centers.

Data is chunked and replicated over multiple systems so that no one system is a single point of failure. Data chunks are given random file names and they’re not stored in clear text, so they’re not humanly readable.
