This post is about Cloud Computing as understood by me, a nonspecialist in technology. A few days ago the CeBit, one of the world’s leading ICT trade fair, was held in Hanover, Germany. During this week, one of the trending topics was Cloud Computing. Then on the TED website, I came across a feature on a company called Akamai, which provides platforms for Cloud Computing. The signs were there, urging me on to write about it. Therefore here I am writing a post about this super-duper what-ever-it-is.
If Cloud Computing conjured an image of a computer in the clouds turning water into food, I have to disappoint you. No, it has nothing to do with resolving world hunger ala “Cloudy with a chance of meatballs”. That would have been pretty cool. However Akamai claims that Cloud Computing would help fight against global warming. How you ask? To find an answer to that we need to define Cloud Computing.
What is Cloud Computing?
There is no single definition of Cloud Computing and so the following explanation is my personal understanding of it. In essence Cloud Computing refers to sharing server capacity by numerous users and/or organisations around the world. A suitable metaphor I can think of is a safe. You can either store your valuables in a safe at home or you can store them in a bank vault or you can use both to satisfy your need to protect your valuables. Storing at a bank has the added advantage, that there is someone looking after your property all the time and they probably have more resources to protect your property than you might have at hand and you don’t have to buy an expensive safe.
However Cloud Computing is not restricted to sharing hardware only. There are services offering licensed software for the users in their clouds. Therefore instead of buying x number of licenses, which at times might be restricted to use in specific devices, you can make use of a software via the Cloud regardless of the device you are using.
How does Cloud Computing support sustainability?
Carbon footprint has become a household term. When you book a flight, you pay a fee to offset your carbon footprint. When you order a package to be delivered to your house, you pay a fee to offset the gases emitted by the delivery van. You cycle to work and walk to the grocery shop. Your conscience is clean. Maybe you should think again. Do you know how much electricity you consume each day? Laptops, iPads & co., mobile phones all need energy to operate. Do you have any idea what your personal carbon footprint in this area is like? I have to admit I don’t but it probably accumulates to a substantial amount in my lifetime.
Companies are all into sustainability nowadays. Cloud Computing helps you be green and at the same time reduce costs. Have you ever been inside the server room of your company? The rooms are usually cool to prevent the hardware from overheating and there are lots of blinking lights, even when no one is in the office working. Therefore there is energy consumption without corresponding productivity or in other words value creation. By joining the Cloud, you are basically outsourcing these servers. You no longer have hardware taking up valuable office space and consuming energy even when they are idle. You store all your information in the Cloud.
Now those offering Cloud Computing platforms do have hardware, with all the associated non-green aspects mentioned earlier. Is the concept really green? The key point is by serving a wider user base, the Cloud can effectively reduce idle time and utilise the server capacity available. Therefore instead of 500 000 thousand servers being used by various organisations, the Cloud only needs about 40 000 servers to do the same amount of work. (These numbers were cited by Akamai in a promotional video.)
How does Cloud Computing impact you?
Chances are you have already had contact with the Cloud in some form. You are simply not aware of it. Akamai alone has some reputable customers and there are so many other providers of Cloud Computing on the market.
Have you ever lost a work laptop? You lose more than the presentation you were working on. There are usually sensitive company data stored in the hard-drive. Data and information equals to money and competitive advantage in today’s world. If you were using the cloud, no data would be stored locally and ergo no data lost and no breach in security to fear.
Security leads me back to the metaphor of bank vaults. It is common knowledge that valuables are stored in bank vaults. Therefore they are often the target of criminals, who want to get rich quick by getting possession of these valuables. Likewise the Cloud might become a target for hackers and if you are unlucky, they might find a way to get hold of your data. By storing data in the Cloud, you are solely dependent on the Cloud to protect it for you.
Every cloud has a silver lining. But clouds could cause floods too. As a private individual, I would probably buy an external hard drive to store my personal data; like photos. As it is Facebook and Google know way too much about me, I don’t need to add the Cloud to that list too. I shiver at the thought of what would happen, if they all joined forces. 🙂 That is my view on Cloud Computing.
