Welcome  to  the  Cloud  Epoch

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

• Cloud  computing  is  just  the  latest  crank  of  the  distributed  computing  handle.  It  is  nothing  more  that  the  natural  evolution  of  grid  and  utility  computing1

• Cloud  computing  is  going  to  transform  has  transformed  the  way  we  consume  IT

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.  !
