Epoch

2. 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.

3. 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.

handle.
It
is

30. 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.
