Big data has become a major issue in today’s world. Put in place by web giants such as Google, Yahoo and Facebook, the idea is to access and analyse huge amounts of data. I am going to succinctly present to you the basic principles, as well as the key figures, and some of the technology used for Big Data. It is in essence taken from the website.
It should be known that approximately every two years, there exists as much data as there did at the beginning of time. You can therefore see that it is extremely important to analyse this mass data. Big data is characterised by the 3Vs:
Volume: is the total weight of the collected data.
Velocity: is knowing the speed at which the data is simultaneously processed.
Variety: is the origin of the data that arrives in a non-structured form.
We therefore need to know how to best exploit this data with maximum efficiency. Conferences are organised on this vast subject. This is why, if the subject interests you, I can heartily advise you to watch the program Big Data Paris.
The figures are significant and we can see that:
- Current market of almost US$ 12,4 Billion
- Market forecast for 2016 of US$ 25 Billion
- Average annual growth rate of 32%
- Approximately 118 Billion emails are sent each day
- Facebook processes nearly 50 billion photos
- Twitter generates nearly 7 terabytes of data per day
You can see that the stakes are colossal and it is only the beginning. It has thus become essentialfor businesses to both understand and use this data.
