Right
for
sure,
I
still
remember
when
I
was
in
Consulting,
you
know,
I
did
a
lot
of
financial
services
work
and
it
was
kind
of
early
days
of
the
cloud
and
even
even
the
later
ones,
but
you
it
was
so
funny
when,
like
having
a
conversation,
you
know
like
sales
or
whatever
like
trying
to
convince
a
financial
services
company
to
go
to
the
cloud
and
and
they'd
be
like
what
about
the
security
and
I'm
like
well.
Why
don't
you
go
and
do
some
sort
of
audit
on
your.
B
A
You
have
some
awareness
of
what
you're
setting
up
again
so
yeah,
so
I've
been
I've,
been
a
big
fan
for
a
long
time.
So,
but
your
real
thing,
as
we
all
know,
is
the
get
Ops
thing.
I
actually
just
referenced.
You
in
my
learning
path
to
say
you
should
go
check
out.
Oh
now,
it's
just
blanked
get
up.
What
was
your
show
I'll.
A
B
A
A
B
So
to
speak,
right
is
I,
always
start
start
with
devops
right
because,
like
devops
really
has
has
been
really
a
movement
right
right
from
like
you
know,
it
I
know
it's
been
years,
but
we're
still
talking
about
it
right
because
it's
you
know,
you
know
it's
a
culture.
It's
it's
it's
it's
it's
a
way
to
do,
work
to
expedite
your
development
process
and
not
a
lot
of
people.
B
A
B
B
There
is
like
okay,
well,
like
I
kind
of
want
to
prevent
drift
at
a
massive
scale
right
right,
I
have
like
all
this
stuff
that
I
want
to
make
sure
it's
all
you
know
all
in
sync,
and
everything
is
how
I,
how
I
want
it
to
be,
and
so
I
think,
as
the
industry
has
progressed
right
like
we
have,
we
saw
this
whole.
You
know
the
whole
past
War
right
between.
B
A
We
were
talking
about,
like
the
you
know,
kind
of
the
history
of
kubernetes
a
little
bit
and,
like
you
know,
he
did
a
really
good
example
of
like
it
was
kind
of
in
the
middle
and-
and
it
was
like
I
can't
remember
his
exact
phrasing,
but
he
said
something
along
the
lines
of
you
know.
Is
it
happy?
Oh,
that
was
it?
Is
it
the
happy
medium
or
you
know
the
nothing
to
no
one
kind
of.
B
B
B
B
One
sres
just
wanting
you
know
to
keep
the
lights
on
right
at
massive
scale
right
and
this
is
and
and
the
the
phrase
get
Ops
was
coined
by
Alexis
Richardson
right
from
weaveworks,
oh
and
do
that
yeah
yeah.
So
it
was
coined
by
Alexis,
Richardson
and
we've
worked,
and
the
story
is
that
the
they
lost
a
whole
region
in.
B
B
Yeah
someone
fat
figure
to
config
right
yeah
and
you
know
the
classic
story
and
they
took
that
a
entire
region
and
they
were
down
for
like
I,
don't
know
20
minutes
and
they
came
back
up
and
which
is
and
I
think
this
is
indicative
of
Alexis
Richardson
he's.
They
said.
The
first
question
he
asked
was:
why
are
we
up
so
soon?
Oh
interesting.
B
Ceo
is
like:
why
are
we
down
right,
he's
like?
Why
did
we
come
up
so
soon
and
they're
kind
of
explaining
the
process
they
had
and-
and
he
goes
oh,
that
kind
of
that's
like
get
Ops.
It's
like
everything,
there's
a
single
source
of
truth
right
for
everything
right,
which
is
where
the
git
comes
from,
get
Ops
right
and
they,
you
know,
developed
internal
tools
and
which
end
up
being
flux,
and
you
know
right
around
the
same
time
into
it,
was
developing
Argo
right.
The
Argo
project
internally
add
into
it.
B
You
know,
there's
there's
two
schools
of
thought.
Right,
like
you
know,
we're
we're
in
a
we're
in
a
Ford
right.
There's
you
know
like
I
say
get
Ops
is
muscle
cars
yeah
and
whether
you
like
Chevy,
is
or
or
Ford.
You
know
like
you
just
like
muscle
cars
right
so
kind
of
like
you,
either
an
Argo
guy
or
a
reflux
guy.
Okay,.
A
A
What
kind
of
one
of
the
things
that
you're
kind
of
getting
at
right
is
like
one
of
the
things
that
is
sort
of
like
the
thinking
behind
kubernetes
is
almost
taken
out
of
config
Management
in
this
idea
that,
instead
of
just
you
know,
basically,
you
know
setting
up
a
thing.
We
describe
a
thing
the
way
we
want
it
to
be.
Yes,.
B
A
Yeah
and
then
we
let
the
system
make
it
true,
right
and
I
think
what's
so
compelling
about
like
git
Ops
right
is
that
you
have
you
have
a
way
to
articulate
it
in
a
way
that
everyone
agrees
is
the
is
the
right
one
you
know
so
whether
it
has
bugs
or
whatever
at
least
everybody
knows
where
it's
all
coming
from.
Yes,.
B
Which
is
huge
right,
yeah
exactly
and
you
know,
and
you
you
touch
an
interesting
point,
because
I
was
at
get
UPS
con.
Yesterday,
oh
yeah
and
you
know
listening
to
all
the
talks,
and
you
know
someone
brought
up.
You
know
obviously
kubernetes
right,
because
you
know
we're
at
kubecon
and
you
know
get
Ops
is
that's
the
Cornerstone
right
where
it
came
from
the
you
know,
the
the
idea
of
the
promise
Theory
came
up
because
of
kubernetes
right
kubernetes,
like
you
trust
the
system
it
it.
You
know
it.
B
B
B
B
B
It's
it's
kind
of
like
it
almost
makes
people
work
together
because
there's
a
single
source
of
Truth
yeah,
all
all
groups,
can
look
at
it
and
say:
okay,
that's
how
the
system
looks
like
right
now,
yeah
and
can
agree
on.
You
know
using
git
workflows
right,
agree
on
what's
going
to
be
on
the
system
right
because
you
know
you've
those
that
use
like
get
workflows.
You
know,
there's
you
know
a
series
of
tests
and
a
series
of
of
of
approvals
that
need
to
happen
before
before
something
gets
merged.
Well,.
A
It's
one
of
the
I
mean
one
of
the
things
I
like
about
it.
A
lot,
too
is
like
you
know.
This
is
actually
one
of
the
reasons
I
started
using
vagrant
way
back
in
the
day
was
because
I
know
for
certain
that
all
the
stuff
I
need
to
run
this
application.
Is
there
because
I
build
it
fresh,
every
time,
right
and
I
think
get
Ops?
You
know
kind
of
brings
that
same
promise
right
to.
B
A
The
system-
it's
like
you
know
so
not
only
am
I
sure
that
whatever
I'm
running
in
production
is
what
I
believe
it
to
be
right,
but
then
on
top
of
that
and
kind
of
getting
back
to
supply
chain
stuff
which
we're
going
to
talk
about
in
a
minute.
But
it's
also
the
same
exact
stuff
that
every
other
developer
has
right,
because
I
still
remember,
you
know
being
like
a
Windows
developer.
B
A
Of
software
and-
and
you
know
increasingly
we're
starting
to
get
the
ability
to
ratify
that
we're
increasingly
get
the
ability
to
like
sign
off
that
it
is
literally
true,
not
just
theoretically
true,
which
I
think
is
one
of
the
nice
things
about
software
that
you
can't
get
with
the
real
buildings.
Yeah.
B
Yeah
yeah
exactly
Yeah,
well
yeah
like
a
manual
inspection
or
something
yeah,
exactly
well,
there's
there's
that
aspect
of
it
as
well
right
because
you
got
your
your
s-bombs
where
basically
it's
it's
just
kind
of
like
an
inventory
of
everything,
and
this
is
really
useful
for
security
professionals
yep,
because
it's
you
know
being
secure.
That's
like
it's
I
always
put
it
in
quotes
because
it's
like
it's
not
like
it's
not
like
a
North
Star
right.
A
B
It's
it's!
That's
like
it's
like
it's
like
it's
a
spectrum
right,
it's
like
like
how
many,
how
much
really
security
is?
How
much
risk
are
you
willing
to
Bear
right
and
the
s-bomb
kind
of
tells
you
okay?
We
need
to
update
this
piece
of
software,
but
this
piece
of
software
we
couldn't
stand.
You
know
we
can
mitigate
that
risk.
B
Somehow
right,
we
need
this
particular
library
for
whatever
reason
right
and
it
may
have
a
vulnerability,
but
we
mitigate
it
in
other
ways
right,
so
you
can
make
a
better
decision
based
on
the
s-bomb
and
it
just
kind
of
just
tells
you
where,
where
it
is
and
another
aspect
of
it
is
to
sign
particular
things
right
right.
So,
like
there's
like
a
you
know,
the
whole
trust
by
verify
sort
of
thing.
B
A
B
A
A
A
Right
and
with
I
think
one
of
the
things
that
people
also
like
I
said
often
don't
realize
right
is
with
the
containerization
of
the
world
or
whatever
we're
getting
a
lot
less,
there's
a
lot
more
models
of
like
software
delivery.
Now
that
are
a
lot
more
kind
of
open-ended
and
so
making
sure
that
we
have
kind
of
generic
tools
like
the
s-bomb
kind
of
push
to
verify.
We
know
exactly
what
is
in
there
and
provable
is
really
really
useful,
because
we
don't.
B
A
A
B
A
A
Wait
what
you
know
you
know
I,
always
like
I'm,
always
kind
of
unhappy
with
red
hat
for
the
amount
of
money
they
actually
put
into
like
python,
for
example,
yeah
yeah,
you
know
it's
like
it's,
so
much
of
lytics
relies
on
python
yeah,
you
know
and
yeah
and
it's
like,
and
but
it's
kind
of
like
in
the
background
round
and
so
you're
always
like
it'll
be
fine,
and
then
you
find
out.
You
know
like
the
over
the
stage
you're
like
nope,
nope
nope.
It
wasn't
fine,
we'll
pause
for
the
goose.
B
A
It's
actually
really
funny
at
Boston
University,
there's
the
like
Student
Union,
like
where
you
know
where
all
the
food
is
and
all
that
stuff
or
one
of
the
many
places
so
Boston.
Like
most
of
you
know,
the
north
of
the
US
has
periodically
a
lot
of
geese.
So
so
there's
all
these
flocks
of
geese
that'll
randomly
wander
around,
but
we
also
have-
and
this
is
in
the
middle
of
downtown
Boston
right,
yeah,
turkeys,
wild
turkeys
and
wild
turkeys
are
also
not
particularly
nice,
yeah
and
yeah.
A
B
A
So
going
going
back
to
get
offs
a
little
bit,
the
one
of
the
things
that
I
think
is
really
interesting
about.
It
is
like
you
know,
trying
to
you
know
kind
of
like
kubernetes
does,
is
you're
trying
to
model
these
things
in
terms
of
you
know
what
you
want
the
state
to
be,
and
that's
a
that's,
a
really
different
way
of
thinking
and
I.
Think
it's
hard
for.
You
know
people
to
wrap
their
head
around.
What
what
do
you
kind
of
recommend,
or
how
do
you
tell?
A
B
A
B
B
Yeah,
even
with
the
cultural
shift
right
a
lot,
a
lot
of
a
lot
of
the
times
get
up
starts
at
the
operation
level,
whereas
you
know
now,
you
have
like
a
ton
of
you
know
before
you
know
in
the
world,
you'd
have
like
a
bunch
of
kubernetes,
sorry,
a
bunch
of
VMS
everywhere.
Right
right,
you
have
VMS
sprawl
everywhere,.
A
B
Have
that
that
massive
sprawl
and
it
starts
with
with
administrators,
really
wanting
to
be
able
to
manage
clusters
at
scale,
and
you
know
again,
you
know
making
sure
they're
all
consistent,
making
sure
everything's
in
the
in
the
way
that
you
want
it
to.
Similarly
to
what
we
had
like
with,
you
know:
puppet
ansible
right
that
sort
of
thing,
but.
A
I
think
what
people
often
don't
realize
right
is
like
we
get
much
higher
like
utilization
rates.
Out
of
you
know
any
particular
piece
of
Hardware
using
something
like
containers,
yes,
rather
than
using
VMS.
The
thing
is:
is
that
what
we
also
end
up
with
is
a
lot
more
of
them
just
like
in
count,
and
so
as
a
result,
you
know
at
scale
now
you
know
it's
it's
possible
right
for
a
single
like
admin
to
manage.
A
B
Know
and
try
and
trying
to
manage
something
right
right,
they're
trying
to
you
know
the
you
know,
organizations
are
constantly
and
I
guess
now,
especially
nowadays
trying
to
do
more
with
less
right
right,
the
the
you
want
to
grow,
but
you
know
they
can't.
You
can't
just
like
hire
your
way
out
of
it
a
lot
of
times
either
right
like
there's
that
that
aspect
of
it
there's
the
you
know
the
I'm
gonna
butcher
this.
This
quote
as
well:
I'm.
A
B
B
A
B
You
and
you
know,
that's
the
organizations
are
demanding
these
things
and
you
know
the
necessities
and
mother
interventions.
So
that's
why,
like
all
these
tools,
things
like
Argo
things
like
flux,
right
things
like
kubernetes
came
out
because
it's
like
okay.
Well,
we
need
to
start
utilizing
our
resources
better
starting,
you
know,
manage
these
resources
better
and
starting
to
do,
you
know,
try
to
grow
with
what
we
already
have
right.
A
A
A
B
B
A
A
B
B
A
A
A
A
A
B
A
B
B
Just
yeah,
it's
all
organic.
What
it's
kind
of
interesting,
how
like
Microsoft
Office,
like
really
Excel,
became
the
king,
where
everyone
thought
it
was
going
to
be
like
like
a
Word
document
right,
but
now
like
now.
Well
now
we
have
like
Google
Sheets
right
and
it's,
but
like
it's
same
idea
right,
like
everyone
lives
in
a
spreadsheet
nowadays,.
A
A
B
B
A
B
They
ate
Badfish
yeah,
and
you
know
you
have
to
you-
know
you're
in
the
cockpit
a
manual
for
the
cockpit,
is
absolutely
useless
to
you
right
because
there's
nothing
in
there.
It
tells
you
what
every
little
Gadget
does.
There's
nothing
in
there.
That
tells
you
how
to
land
the
plane
right
right.
So
my
analogy
is:
is
I
actually
bought
a
Vitamix?
Oh.
B
A
A
That's
cool,
that's
yeah!
That's
one
of
the
things
that
I
always
have
struggled
with
with
development
teams
is
like
when
I
you
know,
had
a
development
team
I've
even
been
doing
it
with
my
students,
when
they're
working
on
projects
is
like.
Okay,
I
want
you
to
describe
how
the
thing
works,
but
I
also
want
a
document
that
tells
that
tells
someone
how
to
add
the
next
feature
you
know
because
like
where
does
it
go?
You
know.
B
A
If
you
wanted,
you
know
you
have
all
these
ideas
for
what
the
project
could
be
in
the
future.
You
know
how?
Where
would
you
put
those
you
know
or
where
would
you
start
to
think
about
putting
those
because
you,
you
have
an
idea
when
you
think
of
this
about
what?
How
you
would
do
it
so
explain
that
in
the
documentation,
because
that
is
as
useful
to
the
next
team,
it
has
like
how
the
thing
currently
Works
yeah
so
but
that's
I,
like
I,
said
zero
to
Smoothie.
That's
really
good.
A
Just
yeah
I
have
one
of
the
like
old
school
ones
and
what
the
one
thing
I'm
really
looking
for,
though,
is-
and
maybe
yours
has
this,
but
I
wanna,
another
I,
don't
know
what
you
call
them
but,
like
you
know,
the
part
that
holds
all
the
stuff
but
I
want
wanna
like
I
want
another
attachment
for
it
that
I
could
actually
make
a
smaller
amount.
You
know
so
like.
A
B
A
A
B
Yeah
to
the
and
actually
to
to
the
point
of
of
of
documentation
right,
yeah
you're
talking
about
that's,
that's
something
I
think
with
like
fast
moving
software.
That's
something
that,
like
I,
think
we
could
all
use
a
lot
of
help
on,
especially
like
I'm
I'm.
The
type
of
person
where,
like
I,
need
to
see
it
work
first
right
in
order
to
intelligently
navigate
the
documentation.
B
B
B
A
B
A
You're
kind
of
saying,
but
the
you
know,
kind
of
that
interactive
documentation,
I
think
is
much
more
useful
to
me.
I,
don't
know
it's
interesting,
I,
don't
know
if
it's
the
type
of
people
who
are
attracted
to
working
in
Tech,
you
know
as
software
Engineers
or
admins
or
whatever
yeah,
but
like
consistently
I've
found
that
most
of
them
learn
better
by
doing
something.
Hands-On
and
I.
Don't
know
if
it's
like
the
particular
brain
type
that
is
attracted
to
working
in
Tech
is
also
the
brain
type.
