Welcome to the Cloud Epoch
Duncan Johnston-‐Watt @duncanjw
Thesis
Cloud is no longer an emerging trend -‐ it is now mainstream. Cloud is transforming the way we think about technology whether we are a consumer or a provider; whether we are tackling a Big Data problem; interested in the Internet of Everything or just want to deliver a better service to our customers.
Promise (Theory)
In this keynote we will look at some of the watershed events that have defined Cloud to date; we will anticipate the gestalt shift in our thinking that is still required to ensure Cloud's continuing and pervasive influence on our lives; and we will explain why this is an epoch.
Epoch
1. a point in time beginning a new or distinctive period: the invention of nuclear weapons marked an epoch in the history of warfare
2. a long period of time marked by some predominant or typical characteristic; era
3. (Astronomy) a precise date to which information, such as coordinates, relating to a celestial body is referred
4. (Palaeontology) a unit of geological time within a period during which a series of rocks is formed: the Pleistocene epoch
5. (General Physics) the displacement of an oscillating or vibrating body at zero time

The Great Rewrite*
Philosophy unravels the knots in our thinking; hence its results must be simple, but its activity is as complicated as the knots that it unravels. !
