Why is Cloud Computing Green?

The promised IaaS article is currently in progress. I blame the delay on my friend Greg from the Green industry .

Last week, I met up with Greg and gave him my usual cool-aid cloud speech on cloud savings, scalability, built in reliability, disaster recovery and security. He looked at me and said, “that sounds exciting” but looking at his facial expression there did not seem to be much excitement, so to get some life out of him, I said, “of course there is significant energy savings!” Now “Green” Greg sparked to life and for the next two hours all he wanted to hear were details on how cloud saves energy.

When making the decision whether an organization is ready or not for adopting cloud technologies, most people will take into consideration aspects such us financial savings, how well it suits their company, and how much it will simplify the IT processes, etc.

What many decision makers do not take into account happens to be a great benefit of cloud computing: it is green! Cloud computing comes with the great advantage of providing great energy savings, a fact which translates into being environmentally friendly.

Are you aware of how much energy IT systems consume and what impact they have on the environment? Did you know that the simple act of performing a Google search can be quantified in terms of carbon footprints? It is easy to imagine then that the maintenance of complex IT infrastructures consumes a significant amount of energy.

According to Gartner, the IT industry consumes at least 2% of all global energy use. Since IT processes have negative effects in the real world, you might want to consider minimizing those by taking into account the implementation of cloud computing. Yes, another great reason to do so…

Here are just a few motives why cloud computing technologies are more environmentally friendly than other types of IT infrastructures and how they contribute to sustainable living:

In the last years, technology has improved immensely, taking the environment into account and providing a solution for those worrying about carbon footprints and the impact of technology into the environment. And with the booming development of cloud computing technologies, now it is easier to do so.

Achieving energy savings and carbon emissions reduction is possible with the help of technologies such as SaaS, IaaS and PaaS and the on demand allocation of resources in cloud computing.

“Green” Greg now feels much better about the cloud! For those of you who have implemented these technologies, how much did the estimated energy savings impact the decision to do so? Are you interested in knowing how you can calculate energy savings?
