Facebook uses large data centers to store information shared on its platform. Each data center contains tens of thousands of servers to receive, store, and distribute user data. In 2015, Facebook spent $480 million on operational expenses for its data centers. The servers use a variety of tools and programming languages like Linux, Apache, MySQL, and PHP.

2. What is Data Center Storage?
Data center storage is the collective term used to define the
tools, technologies and processes to design, implement,
manage and monitor storage infrastructure and resources
within a data center.

3. Facebook Data Center
Each data center houses tens of thousands of computer
servers, which are networked together and linked to the
outside world through fiber optic cables. Every time you
share information on Facebook, the servers in these data
centers receive the information and distribute it to your
network of friends.

4. Facebook Spend on Data Center Storage
It owned about $3.63 billion in “network equipment” as of
the end of 2015 — up from $3.02 billion in 2014. In 2015,
Facebook spent $480 million more on operational expenses
related to its data centers and technical infrastructure than it
did in 2014, according to an SEC ( Securities and Exchange Commission)
filing.

5. Facebook Servers:
Facebook uses a variety of services, tools, and
programming languages to make up its core
infrastructure. At the front end, their servers run
a LAMP (Linux, Apache,MySQL, and PHP) stack with
Memcache.

7. 1. Why does Facebook’s data centre specialist
argue that “The Internet is not a cloud?”
 Because it is a real physical thing, the internet
is a physical building interconnected through
miles of fiber-optic cables all throughout the
world sharing data.

8. 2. What are some of the techniques Facebook uses to
cool its data centres?
 Use a natural air conditioning system, cool air is
sucked from outside, filtered and mixed with
warm air to regulate de temperature. A fine mist
distributed by sprinkles controls the humidity.
Any excess of warm air is pushed out by huge
fans.

9. 3. Describe the five methods recommended by Google for
reducing power consumption.
I. Measuring the PUE (Power usage effectiveness )is the first step. If you can’t measure efficiency,
you can’t manage it.
II. Second, manage airflow by isolating cool aisles from hot aisles, and preventing the premature
mixing of hot and cold air.
III. Third, adjust the thermostat up to operate the IT equipment at a maximum of 80 degrees.
IV. Fourth, as much as possible make use of free ambient cooling such as cooler air, or cooler
incoming water.
V. Fifth, optimize power distribution and utilization. In this case, reduce the number of conversions
from AC (alternate current )to DC (direct current) and back again.

10. 4. Based on the Google video, how much of the world’s
global greenhouse gases are the result of computing?
 The entire ICT (information and communication
technologies) infrastructure including data centers
accounts for about 2% of global greenhouse gas
emissions. Of this, about 15% is due to data centers.
Data center power consumption depends in part on the
rate of economic growth both globally and in the
United States
