Green IT: energetic efficiency in Online Social Network Services Data Centers

Abstract Representation of IT Green Book Chapter

Data centers are a centralized hardware and software infrastructure with cost reduction as its main benefit. The relationship between sustainability and data centers has given rise to the movement called Green IT. Among the data centers, the institutions holding Online Social Network Services (OSNS) stand out.

The objective of this article is to verify how the energy consumption of data centers is treated in the scientific literature and in technical documents, to identify the challenges of institutions that hold SRSO. The sample is restricted to information on SRSO data centers.

An exploratory analysis of the available literature and technical documents made available by the institutions was conducted. All institutions present statistical reports on the energy efficiency of their data centers. The analysis indicated ways to encourage greater equipment efficiency.

The article concludes that the growth of these services places the topic of energy efficiency of SRSO data centers in the foreground, and the reports present initiatives to neutralize the carbon footprint of the holding institutions. The main forms of action of the institutions to reduce CO2 emissions are the buying of carbon credits and investments in plants with clean matrixes.
