The future of data storage isn't on the cloud – it's on the 'edge'

Time travel to the UK in 2025: Harry is a teenager with a smartphone and Pauline is a senior citizen with Alzheimer's who relies on smart glasses for independent living. Harry is frustrated his favourite online game is slow, and Pauline is anxious because her healthcare app is unresponsive. Forbes predicts that by 2025 more than 80 billion devices, from wearables and smartphones, to factory and smart-city sensors, will be connected to the internet. Something like 180 trillion gigabytes of data will be generated that year. Currently almost all data we generate is sent to and processed in distant clouds.
