Cloud is the most scoring buzzword in technology and business spaces. Everyone is talking about the business benefits of cloud - benefits like cost, affordability, storage, etc. It is known to all of us.

Cloud has a flip side also. While there is no problem with data storage, but retrieving and uploading them is a problem. The problem is because of limited bandwidth. But, the way everything is now becoming connected – from jet engines in airplanes to mobile devices in your hands, we cannot reject data connectivity. It is not possible either – because predictive analytics has gained prominence where real time data serves as input and the analytics tools are located remotely. Third and fourth generation cellular networks are simply not fast enough to stream data to and fro. When there is a problem, there must be a solution to it. Experts are saying to stop concentrate on cloud and look at an alternative approach. Christened as ‘fog computing’ by Cisco, it has some edges over cloud computing. In cloud computing, where devices are distant and remote, in fog computing, it is just the reverse. Things are done near to the devices that are not so much powerful, but can make decisions.

So, the next time you go for cloud computing, give a thought over fog computing. Know more about it at: http://online.wsj.com/news/articles/SB10001424052702304908304579566662320279406?mg=reno64-wsj&url=http%3A%2F%2Fonline.wsj.com%2Farticle%2FSB10001424052702304908304579566662320279406 .
