We are all generators of data. From the smart phones in our pockets to our watching of TV on connected devices, the amount of data we consume and generate is rising fast. The photos and videos uploaded to Facebook and Instagram, messages sent via What’s App and WeChat or movies watched on Netflix lead to one common theme – the data is stored or accessed via a data centre.
Growth in data produced globally shows no sign of slowing. According to the Cisco Global Cloud Index, global data centre traffic was around 1.8ZB (Zettabytes – 1ZB = 1 billion Terabytes) in 2010 and is expected to grow to 15.3ZB by 2020: 2 representing an annual growth rate of more than 30%.
In the past, file sharing accounted for a large proportion of Internet traffic but video, which accounted for 63% of all internet traffic in 2015, is expected to grow to 79% of all traffic by 2020. Netflix has been a driver of the demand for video content, with almost 70,000 hours of video viewed around the world every 60 seconds. The move from standard definition to high and ultra-high definition content is likely to increase the amount of data passing through data centres. Moreover, increasing numbers of people are subscribing to this type of service.
