Keynote: Declaring Complexity - Emily Freeman, Amazon
Broadly speaking, GitOps is a way of declaring the desired state of a system. But more than that, it's a way of capturing complexity in a way that the human brain can conceptualize. This talk focuses on the importance of tech developing ways of obfuscating convolution while not exaggerating simplicity.
A
Hi,
I'm
emily
freeman,
I'm
the
author
of
devops
for
dummies
and
a
co-curator
of
97
things.
Every
cloud
engineer
should
know,
I
think
about
all
things:
devops
at
aws,
broadly
speaking,
git
ops
is
a
way
of
declaring
the
desired
state
of
a
system,
but
more
than
that,
it's
a
way
of
capturing
complexity
so
that
the
human
brain
can
keep
up.
A
Our
brains
are
capable
of
incredible
memory,
storage
and
recall,
but
there
are
limits
and
the
truth
is
our
systems
have
long
exceeded
our
ability
for
our
brains
to
keep
track
like
the
machines
we
work
on,
our
brains
are
pretty
efficient.
The
first
and
most
important
step
is
whether
a
piece
of
information
even
gets
stored
in
long-term
memory.
A
You
can
likely
recall
what
you
ate
last,
because
it's
in
short-term
memory,
but
you
probably
can't
tell
me
what
you
ate
for
breakfast
six
days
ago,
because
your
brain
threw
it
in
the
garbage
so
to
speak.
It
wasn't
important
enough
to
remember,
because
your
brain
knows
that
you
don't
need
to
know
what
you
ate
in
number
of
days
ago.
It's
not
important
for
long-term
memory.
A
A
You
remember
a
memory
based
on
a
smell
or
no
a
solution
based
on
a
familiar
pattern.
I
have
a
fantasia
which
sounds
more
serious
than
it
is.
It
basically
means
that
when
I
close
my
eyes,
I
don't
see
anything
just
dark
gray
and
an
aws
logo,
I'm
kidding,
if
I
think,
of
an
apple
or
a
beach
or
my
mother's
face.
I
can't
picture
it
in
my
mind,
there's
just
gray,
but
I
want
you
to
close
your
eyes
and
picture
a
quarter
or
a
penny
or
some
other
kind
of
common
coin.
You're
familiar
with
now.
A
I'm
confident
that
you
know
what
color
it
is
approximately
how
big
it
is
whose
face
is
on
the
coin,
but
what's
on
the
writing
at
the
top
or
what's
depicted
on
the
back?
Where
is
the
year?
It
was
made
printed,
I'm
guessing
you
don't
know.
I
didn't.
I
had
to
go.
Look
it
up
now.
I
thought
I
had
a
pretty
good
idea
of
what
a
quarter
looked
like,
but
I
would
have
struggled
to
draw
it
with
any
real
accuracy.
A
A
We
talk
a
lot
about
abstractions
as
engineers.
Now,
what
we
usually
mean
is
that
we're
obfuscating
logic
or
creating
a
separation
of
concerns
by
removing
overhead
from
an
engineer-
and
this
is
because
computer
scientists
have
long
used
the
word
to
be
removing
certain
details
to
focus
on
broader
concepts,
especially
over
the
last
few
years,
with
the
surge
of
cloud
adoption.
Abstraction
has
become
one
of
those
tech
buzzwords
that
we
all
use
ad
nauseum,
but
never
clearly
define
in
visual
art.
A
A
His
series
of
11
lithographs
called
le
taro
or
the
bull,
convey
a
step-by-step
reduction
of
an
image
from
a
realistic
bull
to
a
sketch
of
roughly
10
lines
illustrating
the
most
basic
form
of
a
bull,
a
true
master
picasso
stripped
the
bull
of
every
unnecessary
detail
while
retaining
the
spirit
or
essence
of
the
animal.
I
think
it
is
one
of
the
most
stunning
visual
representations
of
abstraction
in
the
world.
A
Abstractions
exist
outside
of
art,
museums
too,
on
the
very
streets
we
walk.
The
reason
we
no
longer
build
buildings
like
versailles
is
well
one.
It
was
so
expensive.
A
few
people
lost
their
heads,
but
also
because
something
called
the
modernist
movement
in
the
late
19th
and
early
20th
centuries,
architects
began
to
buck
traditional
aesthetics.
A
You
can
see
the
same
focus
on
shape
and
form
in
the
guggenheim
museum,
also
architected
by
right,
but
here's
the
important
part.
While
these
structures
are
abstractions
of
the
more
traditional,
more
ornate
forms,
they
are
still
very
clearly
buildings
and
picasso's
bowl
was
still
very
much
a
bull.
The
abstraction
didn't
change
the
object
it
simplified
it,
so
it
could
be
observed
and
consumed
in
a
different
way.
In
this
distilled
form,
it
is
more
purely
itself
and
somehow
I
think
in
that
clean
simplicity,
it
more
boldly
declares
itself.
A
Abstractions
are
useful,
not
because
they
distract
or
ignore
data,
but
instead
hone
in
on
the
important
bits,
git,
ops
and
other
abstractions
are
our
modernist
movement.
We've
developed
ways
to
better
see
the
essence
of
our
socio-technical
systems,
but
more
than
that,
we've
created
a
way
to
declare
our
vision
for
what
our
system
should
be.
Not
just
observe
and
react
to
what
it
is
out
of.
The
modernist
movement
came
this
manifesto
of
futurism
and
in
it
a
poet
described
futurism
as
a
rejection
of
the
past
and
a
celebration
of
speed
and
industry.
A
I
am
fascinated
by
the
fact
that
speed,
futurism
machinery,
revolution
and
abstractions
were
tied
together
long
before
a
computer
was
a
thing
for
me.
There
are
two
rules
of
abstraction.
The
first
is
that
it
must
be
reversible,
abstractions
purposefully
detail,
but
it
doesn't
mean
that
the
detail
isn't
important,
and
this
is
where
git
ops
infrastructure
is
code.
Sometimes
even
good
old
source
control
becomes
critical.
A
If
we
strip
the
photograph
of
all
its
color,
we
can
more
clearly
visualize
the
way
that
light
creates
her
shadow
and
lines,
and
if
you
sketch
over
it,
you
can
highlight
the
strongest
lines
of
the
original
photograph.
You
can
still
see
the
stairs
in
a
sort
of
balcony
on
the
left.
You
can
imagine
a
window
above
the
negative
space
on
the
right,
but
I
want
to
go
even
further
and
abstract
this
to
its
most
basic
lines
and
shapes.
A
Now,
when
I
made
the
image
partially
transparent
and
really
squinted
my
eyes
to
see
only
the
most
prominent
features,
I
ended
up
with
this
now
outside
of
being
clearly
the
next
modern
masterpiece.
This
is
an
example
of
abstraction.
Going
too
far,
the
only
reason
you
have
any
clue
what
it
represents
is
because
you
have
the
knowledge
bias
of
seeing
the
original.
