Google Data Centers
Google data center are the large data center facilities Google uses to provide their services, which combine large amounts of digital storage, compute nodes organized in aisles of racks, internal and external networking, environmental controls, and operations software. [1]
Explore over a decade of innovation at Google data centers. [2]
• 2001, Google has been designing their own servers to reduce their energy use since 2001 by using highly efficient power supplies and putting batteries directly on the machines, Google has built some of the most efficient servers in the industry.
• 2003, Google designed portable data centers

This was the main machine for the original Backrub system.
• 2 × 300 MHz dual Pentium II servers donated by Intel, they included 512 MB of RAM and 10 × 9 GB hard drives between the two. It was on these that the main search ran.
• F50 IBM RS/6000 donated by IBM, included 4 processors, 512 MB of memory and 8 × 9 GB hard disk drives.
• Two additional boxes included 3 × 9 GB hard drives and 6 x 4 GB hard disk drives respectively (the original storage for Backrub). These were attached to the Sun Ultra II.
• SDD disk expansion box with another 8 × 9 GB hard disk drives donated by IBM.
• Homemade disk box which contained 10 × 9 GB SCSI hard disk drives.
Production Hardware
Google used as of 2014, a heavily customized version of Debian (GNU/Linux). They migrated from a Red Hat-based system increase in 2013. The total server workload and CPU power consumption may be a major factor. 2009-2010 includes a custom shield system consisting of two processors. The amount of RAM that is spread over 8 DIMM slots and at least two DIMMs. Disk drives connected via standard non-standard ATX memory are server-based on top so servers can load more data into the rack.

They keep user's data safe and secure by using dozens of critical security features. Google has designed their data centers with security in mind. Security is part of our data centers' DNA. They build custom servers exclusively for their data centers, never selling or distributing externally. Google has also designed, so it doesn’t unnecessary hardware or software to reducing the number of potential vulnerabilities. Google also have robust disaster recovery measures in place. For example, in the event of a fire or any other disruption, Google shift data access automatically and seamlessly to another data center so that their users can keep working, uninterrupted. Their emergency backup generators continue to power their data centers even in the event of a power
