Cloud computing saves energy?!

Our future will be shaped by four major trends in IT investment: cloud computing, data security, big data and mobility, according to Hewlett-Packard CEO Meg Whitman.
When you take a closer look at the IT market, you could not agree more.


Cloud computing has great potential. “Data centers consume about two percent of the world’s electricity. If the cloud were an independent country, it would rate number five in energy use. China is number one, the US is number two, Russia is number three, India is number four and the cloud is number five, and Japan is sixth,” said Whitman.

So how can it be energy saving? Giving up a traditional model of computer in favor of cloud computing shows great potential.

“Total spending on public IT cloud services will grow from $16.5 billion in 2009 to more than $55 billion in 2014,” says IDC main analyst Frank Gens.

The research conducted by IDC also shows that cloud computing includes such benefits like: cost optimization, short implementation time and flexibility.

“Virtualization technologies are used to enhance the application load on server systems and allow a more efficient use of those servers. Cloud computing magnifies this effect. The resources are brought together and then dynamically distributed where needed, which guarantees their efficient use and makes them eco-friendly,” says Microsoft Polska Product Manager Bartłomiej Machnik.

Companies which choose to move their resources into the cloud quickly notice its positive effects on cost reduction and environment. Electricity consumption is lower, and what is more important and often forgotten about, there is no need for hardware utilization.

The situation is slightly different in the case of cloud data centers as e.g. Google computers’ annual electricity consumption is about 3 billion kWh, which is more or less the consumption of a large city.

However, it is worth emphasizing that “in a company which has moved all its hardware and applications into the cloud you will not find complicated server rooms with cooling systems or emergency power generators. Its electricity consumption connected with data center management will be lower and as a result the CO2 emission will also decrease. On the employees’ desks traditional PCs or laptops will be replaced by energy-saving terminals directly connected to IT resources in the cloud,” says Tomasz Jangas of Hitachi Data Systems. “If such organization were implemented in thousands of companies and public institutions, enormous potential of cloud computing as a service which helps protect environment would be easily noticeable.”

Undoubtedly, it is a legitimate statement which not only emphasizes the whole point of cloud computing but supports concrete financial and environmental arguments for using the cloud service such as ComZetta.

It is worth noting that cloud users may increase their computing power whenever they need it. It is possible to carry out complicated operations, which usually require a high-quality processor and a lot of RAM, using such devices like a tablet, Smartphone or an older PC. The whole processing is possible thanks to ComZetta – your cloud computer. You gain “zetta power”, save energy, cut costs and you’re green!
